Transcript:
7:00 p.m..Scott Roberts: Welcome and Intro
was there last uh just before no no no no yeah i was i left there many years ago
7:05 p.m..David Levy
we lost the lead i think you pressed the wrong uh the wrong choice
yeah there was a yeah it just went live so we'll we'll we'll get him back yeah he'll be back yeah he'll be back yeah
7:15 p.m..David J. Eicher
david uh in one of our reach out and touch space panels we got to have one of your uh associate editors uh join us on
astro radio in the uk who who was uh with you um i'm trying to
remember her name it's uh allison oh she's she's involved in curating the
7:35 p.m..Maynard Pittendreigh Astronomical League Door Prizes
uh the space and beyond packages um it might be allison i'm trying to
7:45 p.m..Sybella Burlingame
find i'm trying to find the name because i have it in my notes i just can't find an allison or or caitlyn or hayden it was
katelyn caitlin yeah well good i'm glad to hear that we had a blast we were chatting all
7:55 p.m..Adrian Bradley
about uh kind of the state of the of uh periodicals and astronomy magazines
these days yeah well i mean so much that was terrible
you know happened last year of course but you know as we've talked about here before
8:15 p.m..Molly Wakeling- Astronomolly's Universe
it exploded the the hobby you know i think after people cycled through netflix for a couple of months
you know they were basically stuck at home there was quite a boom you know in amateur astronomy which normally you
only see with a terrifically bright comet you know so or or like last summer
8:30 p.m..Karim Jaffer
exception the the the one exception to that in the last 40 years has been the
the impact of shoemaker leaving ukraine into jupiter also had that effect but but last year we had a the hobby was
8:45 p.m..Ten Minute Break
enriched with a huge influx of new interests so so things are going very very well
i will be plugging your space and beyond box with the moon flash cards today
8:55 p.m..Jerry Hubbell
well thank you very much i love these because uh we've been doing crater sketching up here in montreal a lot and
9:05 p.m..John Briggs
i print out high resolution images and everything but just having the flash cards and being able to put them in little frames at people's tables when
they're sketching it's so useful well i'm really glad to hear that they seem to be popular
9:20 p.m..Deepti Gautam
and i think there are many more sets of those coming on down the road excellent
cameron what i was trying to say before i was thrown off of the web here is that i'm sorry i didn't see you when
9:30 p.m..Maxi Falieres – Astrophotography in Argentina
i was in at the uh aurora 360 thing just before the covert thing yeah maybe next time oh
yeah no that's no that that's right actually david um i hadn't been back to yellowknife for
9:45 p.m..Cesar Brollo
many many years i i uh i was um it was back in the 70s
when i went when i was last there so it was yeah exactly so it was uh many many years ago but i i
10:00 p.m..Steve Mallia
do remember as a child uh looking up uh even probably i was maybe five years
old or so and looking up and looking outside the car window and seeing the aurora burials
10:10 p.m..Cameron Gillis - Camstronomy
right overhead like super bright and and casting shadows uh there was some very impressionable
northern lights uh views up in yellowknife when i was a child well where are you living now
10:25 p.m..Ten Minute Break - After Party
i live in seattle yep so i went did did i went to went to was in
toronto for a couple years um and then vancouver dallas and then
10:35 p.m..Pekka Hautala - Connections with the Universe
bay area and now seattle it turns out that on my way to yellow one night
in 2019 i went through seattle was the last time i was in seattle
yes yes from time to time oh cool well i have to have to see i i
was in arizona actually uh a year and a half ago i went to uh a conference just
before covet hit and uh and and uh and that's that's when they that was my
last travel actually before would uh shut down a lot of the traveling i was there in
january 2020 so i was in your neck of the woods and uh but yeah i would uh
would love to see you sometime in person yeah me too yeah
and i think we're going to get there with this uh you know i think we're you know now they're doing
boosters and stuff but i think we'll get through this covid um
you know it's uh kind of learning the ropes and uh you know other countries are coming if they are are trying to figure it out of
course for themselves but i think that it's going to run its course and we're probably going to live with different variants of covet for a while but
i think we're getting the pros procedures down to to make it so that you know with masking
and vaccination i think we can we can function again and see each other again
yes cameron you know it's uh up near yellowknife it for a long long time it was in
western australia but now more recently in the last few years it's up near yellowknife where some of the oldest
rocks on earth that are exposed of course have been discovered up in that region
where you're where you're from there actually david david um you were right on in fact you know the
name yellowknife where that come from is because of the tribe up there is you know the yellow there's gold on the
surface uh and and there is every type of mine up there in fact uh that's what
bringing everyone up there geologists i mean they have uh copper silver gold diamond uh you know every type of uh
mineral and of course they from yellowknife is kind of a hub for the geologist going up to the to the arctic
um to to look for um you know oil and all that stuff so so it's a major um
yeah you're right it's a geologist's dream that that area really
and i really enjoyed being there and seeing the northern lights right at sunspot minimum
you're not supposed to be northern lights and you're saying i'm very sorry but i have to give you a display anyway
yes as a kid that would they had this uh other um one um other chris uh
crystal they call it fool's gold um up there there was a lot of that right
yeah yeah that's very very very common stuff yeah yeah yeah that's that's all
over the place as kids we would always play with that and pretend it was gold well looks it looks very much like gold
thus thus the nickname uh but it's an iron sulfide yeah
yeah yeah it tends to go in veins right you have
like veins of it going through yeah and part of the confusion for the old miners
in the old days is that just like gold it forms very frequently in veins of
quartz that run along you know subsurface so it forms in a lot of the same places
as actual gold does as well just to make things extra confusing
yes yes yeah it's it's really neat and of course all the
different chemical processes to separate all those ores right for extraction yeah
really fascinating actually yeah david i'm i'm curious uh
what role does anaerobic bacteria play uh
with um you know the various oxides and stuff that
exists today well he uh their microorganisms of a whole variety of
sorts played a huge role and in fact you can look up there's there's an event about 2.6 billion years
ago that was called the great oxygenation event um or the great oxygen event
um which which was the point on earth's you know for for a long long time for
more than a billion years all the life on earth was just microbial of course and by the time
oxygen producing microbes produced a critical amount of oxygen such that
there was a lot of free oxygen in the atmosphere that transformed life on earth
and also tripled the number of mineral species
from about 1500 to about 5 000 or so that are known now because oxygen of
course which is good for us as living beings and for everything of course is extremely highly reactive you know so it
likes to react with other elements so that made a huge number of more of more
oxides and other kinds of minerals as well as uh pushing life forward
in addition so so the goe as it's called was a major important point in the history of earth
that is really ties together with dr barth uh had a session on on monday uh about about that about the changing
of the chemical composition of the atmosphere from the microbial life and affecting you know actually the oxygen
is toxic to uh to that certain microbe yes
yes but if not for the if not for the microbes producing a huge amount of free
oxygen you know we wouldn't be here among other events that happened so exactly
it's fascinating yeah i love that
well i'm busy sharing um to various groups uh
i'm gonna i'm going to share it to the dogs and cats of space and astronomy which is
i just love the name it's not a huge group but quality people it belonged to this group so i start a little while ago
when when we were talking about other things that sebella had had a cat of astronomy there yes she did that's right
that's right so mammals other than humans are represented on the broadcast here there
we go here is mr cat oh there you go
yeah we we can see it yeah
is this the 58th uh gsp tonight is number 58 yes sir thank you that's
p.m, 03:45 Nicolas Arias
what i thought we're 58 can you believe that we have done 58 global star parties
that's awesome when i look back on it in the you know the
some of the marathon ones that we did you know uh in particular the great conjunction you
know oh yeah that was uh that was something [Laughter]
actually that's how that's how he found you guys he really i mean he was he hung in there for the duration of the whole
thing so i was like wow it's nice steve is on
tonight is that your astro cat sabella
yes she's stolen my chair will she be giving the presentation
tonight i don't know she might help she might help okay all right
her name's maddie maddie nice cat that's cute
like how she phases in and out of the universe
so karim i forgot uh you you were um you're you work at the university right
at ceja it's basically the equivalent to uh last year high school first year
university that's one it's a transitionary college it's uh only in quebec they have these
so you must be you know now it's getting to the next uh next year so we start on monday
we start on monday yeah and uh they just announced last monday that we'll be in person so we're
switching all of our first four to six weeks of activities that were planned online now into in person again
all right that's gonna be i think uh yeah we're kinda my daughter
is going to her her senior year and uh she had the he she had a virtual year and junior year
and now senior year she's going back and uh i think they're going to be ready i think they'll be
we are putting a lot of effort in all of us to to be ready i know i've talked to several teachers at different schools
and everybody's really trying hard you know it's it's it's a lot to change
but it's i think we all feel it's a needed change so yep yeah it's important it's about
something kareem uh the technology of of doing of teaching um you know online will that
carry over or will it stop you know uh that's the big question i actually was just talking to one of my colleagues
who's a couple of hours away who does he used to be doing in-person visits to my class every fall
and we were chatting because it's it's a lot for him to find somebody to take his classes leave
his research behind for a day or day or two sometimes and just be able to come spend time with the students and go back
and it's hard when we can't line up multiple classes for him to visit so
i'm gonna find a way for him to do just a zoom call into the class this time around sure and see if it has but it doesn't
have the same impact all the time right so one neat thing is you can have experts
from anywhere call in and be your zoom visitors or your zoom experts to come in
and talk about certain things so i'm gonna take advantage of that and i'm gonna have mentors set up for some of my
project teams from even overseas mm-hmm excellent
actually one neat thing that i can talk about i guess now is i've gotten acceptance to be part of the fox
telescope project for my outreach and teaching so i now have access to southern hemisphere
telescopes through the lco well that's wonderful congratulations
thank you now i just got to figure out how to fit everything in
so many fun projects remember what bart bach used to say
all the good stuff's in the southern hemisphere it really seems like
it wasn't too much of an exaggeration
yep [Music]
astronomers using archival data from nasa's hubble space telescope found evidence of water vapor in the thin
atmosphere of jupiter's moon ganymede ganymede is the largest moon in our
solar system larger than mercury and pluto and three-quarters the size of mars
it's an ice-covered world that may hold more water than all of earth's oceans combined
but unlike earth ganymede's oceans are below its 100 mile thick icy crust
ultraviolet images taken in 1998 and 2010 using hubble's space telescope
including spectrograph revealed bands of charged particles at ganymede similar to
earth's polar auroral ovals the regions that give us our northern and southern lights but the two observations revealed
differences in ganymede's auroral bands over time the researchers thought these differences were due to the presence of
atomic oxygen or single oxygen atoms in ganymede's atmosphere atomic oxygen
affects one of the wavelengths of ultraviolet light the scientists were looking for in 2018 researchers used hubble's cosmic
origin spectrograph to measure the amount of atomic oxygen in ganymede's atmosphere they compared the 1998 2010
and 2018 data to their surprise the 2018 data revealed hardly any atomic oxygen
in ganymede's atmosphere there had to be another explanation for the differences in the aurora images ganymede's surface
temperature varies widely throughout the day and around noon near its equator it may get warm enough for surface ice to
release water molecules instead of melting and forming liquid water the icy
surface warms and changes from a solid directly to a gas a process called
sublimation looking back at the original images the team discovered the differences they
observed in ganymede's auroral bands are related to where water vapor would be expected in the moon's atmosphere
understanding the jovian system and unraveling its history from its origins to the possible emergence of habitable
environments will provide us with a better understanding of how gas giant planets and their satellites form and
evolve along with learning more about jupiter and its mysterious moon ganymede this
exciting new discovery has brought us closer to understanding our own place in the universe
[Music]
well hello everybody this is scott roberts from the explore alliance and explore scientific
and welcome to the 58th global star party our theme is moons and moonlits but uh you know that
theme can take us anywhere in the solar system or for that matter anywhere in the universe
um the uh you know when when we look back in the history of uh astronomical
observations of moons uh you know of course there's much lore and and
and much fascination with earth's moon but uh you know it was i believe january
beginning of january 1910 that galileo observed moons going around
um jupiter and it took him about a week to sort of figure it out but uh this was
this uh uh this realization and this discovery you know changed the entire face of
astronomy and um really i think launched the modern era of astronomy with uh
you know telescopic instruments so um it's uh
i think it's an apropos um topic and uh
uh theme for for this particular star party uh you know we've had uh
um you know jupiter is coming to opposition we've got um you
know saturn just past opposition and if you watching either one of those planets you've been also watching its moons in
in their orbits and so um i uh
you know i've always been fascinated by the moon uh a story i will tell you is on one
particular night at palomar observatory they had a 60 inch they still have a 60
inch telescope up there and um i was with an astronomy club and
we were in line to look at different astronomical objects the
telescope operator first turned it on the moon and there was like
it looked like a spotlight of like hitting the floor of the observatory through the eyepiece okay
and all these you know pretty much died in the wool amateur astronomers you know
avoided looking at the moon uh because they just got you know the light's too strong i don't know if they thought
their eyesight would be hurt but you know i knew that it's just reflected sunlight so couldn't hurt any more than
looking at mountains during the daytime and indeed when i looked through the 60-inch uh without any filtration on
you know it was just amazing seeing gentle rolling hills uh you know thousands and thousands and probably
tens of thousands of craters in an eyepiece field of view at the same time so that that's had an effect on me uh my
entire uh amateur astronomy life and so
i'm sure all of us have various stories and impressions about uh about the moons uh our in our solar
system of which i think there's over 200 have been discovered is that is that right david
yep something something in that neighborhood i think we'll still discover more you know they are finding
also moons around exoplanets and of course there are the moonlits uh that uh are you know in our solar system
and eventually they'll find them in exoplanets as well i'm sure but uh
for now i will turn this uh star party over to david levy uh david
is uh um we were all talking earlier maybe you've heard some of the conversation but we're all talking about
us getting out to star parties and uh which we all want to do um but also the challenges of this
pandemic and uh so um you know uh as you as you start to
venture out uh star parties and stuff you know be safe that's what we'd like for you to do
and um uh you know we we all hope to see you out under the stars sometime in person
david i'll turn this over to you my friend and uh thank you for coming yet to another
uh global star party well thank you scotty and david and everybody and it's
good to be back and welcome back scotty thank you um i think we should all know that the
astronomical league has its annual convention thursday friday and saturday and this
online you need to register but it's free
and i hope all of you right now as soon as even now instead of my talk just go and
register for it and be there it starts at three o'clock eastern time every
on thursday friday and saturday and um
i've been given a 35 minute window to give a presentation that i'm going to
give and i'm going to give you you know let you in a little bit of that presentation today and so
with my apologies today's weekly poetical reading will be a little
longer than usual i was in the habit of calling my dear
friend carolyn shoemaker every monday uh you know i hadn't been in touch with
her in a while and then during one of our adirondack astronomy retreats i'm not observing
with the telescope excuse me
excuse me sorry anyway i was out with one of the telescopes the phone rang and it was
carolyn and uh i was looking we had a wonderful
conversation i was looking for a way to be in touch with her when wendy said you know you call your
brother richard every week why don't you call heroin as well and i started to do that so for about a
year or a little more i had been calling carolyn every monday
until this monday when it went directly to our voicemail
i called her repeatedly left her an email left her messages
and then on uh what she was on wednesday night her daughter called me linda called me
to say that carolyn had suffered a minor fall and she had been taken to the hospital
and uh but it looked the news could have been much much worse
so we were in a way relieved that she seemed to be getting okay however the following night
linda sent a message that carolyn had gone into respiratory arrest and um
on friday august the 13th at 10 40 carolyn died
and uh we have lost carolyn shoemaker
the talk that i'm going to be giving at the astronomical league this weekend at some point
is titled this did carolyn shoemaker have a sense of humor
i'm not going to answer that right now except that i am um they're i'm going to share two of
those little stories uh we started observing together in august of 1989.
i was doing he carolyn taught me how to load
the films and the procedures for loading the films into the camera
which seemed to be pretty conv convoluted but i got the hang of it pretty quickly and by the second night i
was i was loading him up pretty quickly and carolyn said you know
uh as fast as you're going we may run out of film
and about 10 minutes later i came up and i said well that's it carolyn that's the
last film and she said what and i said well you were right we've
been out of film but i have a plan i have 35 millimeter strips of film with
me and what i've decided to do is take the film and lay them out into the film holder
one one slide after another until we get the whole thing
and then we held them together with scotch tape and carolyn looks at me and
she says i don't think that's going to work david and i said oh sure it will
you just take the scotch tape and put it together and stomp on it a little bit and it'll hold the
strips of film together and she's thinking to herself how do i tell this apparently very nice
who i thought was an intelligent young man he's a total idiot
and finally she looked at me and said
you know if i didn't if i didn't know you any better i would think i i get the strange
feeling that i've been had and then i looked at her and i said carolyn i think that's because you've
been mad anyway that started things
and the other story is in 1994
gene was spending a lot of time away so it was carolyn and me doing a lot of the observing but in the march
observing rung we had peter jediki join us and carolyn would be just doing the
scanning and peter and i would be handling most of the observing and peter is also pretty quick
but peter and i were also a little nutty and we decided not to use the traditional
little timer that would ring every eight minutes to remind us of the end of the exposure
and instead we had a little song that we would do and about about 10 seconds before the end of the
exposure peter and i would take a deep breath and we'd go be kind to your web-footed friends
for a duck may be somebody's mother they live in a hole in the swamp where
the weather's cold and dump well if you think that this is the end
well it is and clap we closed the shutter at that point and uh then i loaded the film into the
unloaded the film from the telescope and brought it downstairs and i opened the door and carolyn was
doubled over over the stereo microscope i said carolyn are you okay and she slowly lifted her head off of
the serial microscope her eyes were red as anything and she was trying to
struggle for breath and she said sorry david i have never enjoyed observing as much
as i am this night i am having an absolute blast
and uh we just laughed and left and it was so much fun
and i carolyn has said many times if the observing we did wasn't fun
it wasn't the hell worth doing and you're here and uh that's sort of
the beginning of the talk that i will give at the league convention on saturday and with that i give it back to
you dr scotty roberts thank you for the honorary title
[Laughter] oh thank you well our next speaker uh is none other
than david eicher from astronomy magazine uh he is uh he's taken us to
the depths of space he's described galaxies to us he has uh
uh given us the uh the the inner workings of of much of the
you know the construct of the universe and uh you know i love i love hearing his uh
his his uh insights and um you know the current science of what's going on um
and uh today uh david uh joins us after uh he would have been here last week but
you know i wasn't here last week so we're kind of all of us are sort of
joined at the hip this kind of thing but uh um it's uh it's my pleasure to um
reintroduce if you have not uh seen david eicher talk before you'll
enjoy this um so david i'm going to turn it over to you thank you scott and and thank you david
for that uh great remembrance of carolyn we've lost a giant here and and for many
of us who were young you know in the 1980s hanging around people um she was sort of a mother figure in in
a way and david i met her through you of course hanging around you and brian skiff and and flagstaff and and
it's a it's a tremendous loss to to the community as it was of course when we lost
gene um [Music] yes yes indeed she had a good long life
and what a brilliant and funny person she was yeah and looking forward to your talk on
on the weekend david david may i share my screens scotty let me try
absolutely if this works i will share a powerpoint it will cost you that
i'm sorry dave david oh just saying it's going to cost you the share of the screen
okay put me down scott i hope my credit is okay i'm sending a card that you you know as card
swiper machine so that you can just do that anytime i call you so gotcha
thank you very much can can you see this title slide yes it's beautiful look at that what oh
good that's a beautiful mineral well i'm going to talk a little bit again about minerals and about atoms and
about as another friend of ours dear departed friend of ours carl sagan used to call cosmochemistry and and how the
universe makes planets a little bit tonight and and i've was infected with this interest
which is really planetary geology many years ago by my father who was interested in all kinds
of things and was a chemist himself and so i've got a collection of mineral
specimens which is really how the universe makes matter in an organized way
i've got about 1500 minerals i think i'll show about 10 tonight so scott i have
sort of bad news we can only do this 150 more times 151 yeah
i'm i'm all for it man we'll have to get get some new ones but this is a this is a tanzanite crystal
here which is a variety it's a silicate mineral called zoocite and of course this was
named this gemmy blue purple uh variety of that mineral silicate was
called tanzanite in the 1960s basically as a as a commercial marketing move uh
because the great gemmy crystals of this come from tanzania but it's it's a beautiful way to start off and just to
to sort of you know start talking let's talk a little bit about elements tonight these are the basic uh chemical
substances that are made out of atoms as we've talked a little bit before the average person
uh has seven octillion atoms uh in them that's seven billion billion billion
atoms in your body that make you up um and they were created literally in in
stars in in dying low mass stars and exploding supernovae
in very dense neutron stars that collided with each other uh the lightest elements in the early history of the
universe so you're literally as we've talked about made of star stuff and this is how the universe
makes the simplest substances it wants to put together in an organized way
there are 118 known elements 94 of those occur naturally in nature
and and the rest have been assembled in laboratories temporarily if
you will um and of course they tell us a lot about how the universe likes to put things
together as i say because this is not an accident however the
universe makes things whether it be planets or stars or galaxies or trees or cats or
dogs or people or minerals the the
atoms that come together to make up substances are electrochemically attracted in a specific way to each
other so for example to take a really simple example of halite uh the simple
mineralism table salt um you know if you eat a couple of potato chips you're you're consuming a
whole lot of these crystals um and these are just made in an organized way of sodium and and chlorine atoms that are
structured and attracted to each other in what what mineralogists
call a crystal lattice that makes up the framework that makes up these basic
mineral substances and then of course more complicated things uh happen
to assemble in molecules and in what chemists call compounds
which you know we'll talk about another time but in a simple way this is the way the universe makes planets it assembles
them in in a very orderly uh not an accidental but an organized way
because they're attracted to each other in specific ways electrochemically
so rather than trying to show things microscopically as we've done a little bit or or
hold them up to the screen i do have them here the ones i'm going to show which i can hold up if you if you'd like
to or asked to but i'm showing a few slides uh tonight and i'd like to talk a
little bit about some of the basic kinds of minerals they're about 5 000
mineral species types of minerals on earth and we have a lot of them as we were
talking as the show was warming up because more than 2 billion years ago
earth its atmosphere uh if you will reached a tipping point of a tremendous amount of
free oxygen in our earth's atmosphere that were being produced by science by very
primitive life forms that were around for more than a billion years called cyanobacteria
and others and as soon as there became a a huge amount of free oxygen
suddenly in our atmosphere not only did that make more uh complex life
um possible and evolution uh could go in different and more complex paths but it
tripled the number of mineral species on earth from about 1500 to about 5 000 so
a place that doesn't have a lot of oxygen like mercury or the moon for example can't have very many mineral
species compared to what we have well this is gold here this is from the eagles nest mine in placer county
california and this is simply a native element of course sitting a little bit of crystallized gold sitting on a quartz
matrix here uh which is mostly quartz well another oh let me see if i can i
can't um oh dear let me see if this works no no
okay there we go there's a button i have to press sharing the screen here this is another native element here and this is
a large specimen here i don't know if you can see me and also the but this is
a pretty good hand-sized specimen of silver this is a native silver leaf
crystallized silver another native element a very simple on the
periodic table if you will it's from morocco where there's a very
rich region of silver of course in the american west there's a great long tradition in the 19th century
especially of gold and silver mining this is from morocco up high in the mountains and you can see that silver
sometimes crystallizes in this leaf habit if you will
so that is another well-known native element
then one of the most common types of minerals on planet earth is called
quartz so if anybody tells you on ebay or anywhere else that they have an
extremely rare courts they want to sell you you know you have a problem with them uh
because it's very very abundant but there are some unusual kinds of courts this is what's called boulder opal
uh from australia where a lot of this uh occurs it's fairly rare as quartz goes
and you can see these kind of iridescent colors in the crystallized quartz and this is because opal
is not just ordinary quartz which is silicon dioxide
but it is a silicon dioxide hydrate so it has
water um that is in there locked in the mineral crystals with it and that allows
this diffraction effect we look at light uh going into opals and
they diffract the light through these crystals and and create this play of all
sorts of colors and so that makes it an interesting and and treasured kind of
quartz for jewelry and for other things like that but it's basically a pretty pretty
simple mineral overall then we get to some slightly more complicated kinds of minerals this is a
of the car so-called carbonate family of of minerals this is manganese carbonate
uh uh its common name is rhodochrosite this is a stalactite of of rhodochrosite
uh that's that's in part name because it's rose-colored and has been sliced here to show the inside of the
selectite this is a common occurrence in argentina in a region of argentina where
this is from um and it's the uh impurities often in minerals that the
the little uh occasional manganese atoms that that are in this particular sample
that give it its color but there are a variety of causes of colors in different minerals this is a
pretty one rhodochrosite and it's a little bit soft for jewelry but it's one that's often
loved by mineral collectors because of the color this is a very common one as well it's
called fluorite here and this is a south african specimen of fluoride it's calcium fluoride
caf2 very simple mineral it's extremely abundant it's it comes in all the colors
of the rainbow if you will um including white and black um so mineral collectors love fluorite
because it it comes in not only some different crystallizations some octahedrons and just plain old cubes and
other shapes but you can get it in basically any color it it's very similar
to to the compounds that are added to our toothpaste to help protect our teeth
yes this is another one that is uh popular with mineral collectors you can
see some of them are oriented toward the camera a little bit here on this
specimen i don't know if you can see me also but i can hold this up and change the
the angle this is wolfinite which is a lead mineral and lead
get those minerals very rich colors of red and orange and yellow and
this is from a famous mine called the red cloud mine in arizona
this is wolfonite is lead molybdate so lead and molybdenum
together produce these tabular very richly colored crystals and you can see it's on a
matrix rock with a little bit of quartz running through there the rock and the so-called matrix that holds the minerals
uh the crystals of various kinds of minerals is often just called by geologists country rock the kind of host
rock that that the mineral specimens are embedded within
this is another one that i don't know you may be able to see the actual specimen here is a fairly good size this
is another one that has been cut and polished and this is a favorite of mine for a couple of reasons i love this very
strong yellow color comes from this is a variety of a mineral called smithsonite which is
another carbonate it's a zinc carbonate and it's thought that the strong yellow
color of this mineral comes from cadmium atoms which are in
there as an impurity if you will this one has been cut and sliced and polished
as well this is from an italian location in sardinia it's a fairly rare color and
type of this mineral but it's been cut and polished to show this kind of banding that happens within the
mineral specimens here so you would call that smithsonite which is named after
the fellow the english fellow who never made it to the united states but he gave his fortune in the early 19th century to
the american government to form the smithsonian institution james smithson named after him and and
this is a particularly beautiful kind of it i think this italian
type that is a very strongly yellow colored then here's another kind of mineral that
uh that often is used for jewelry this is in its native rock here you can see
the image and here's the pretty good size hand size specimen this is a called grassular but it's one
of the half dozen or more types of from the garnet family which is a
whole family of closely related minerals you can see the crystals here in the rock
called garnets this particular one called grossular and it's from a mexican
locality uh it's often called raspberry grasular
as a nickname because of the strong color of these uh these garnet uh or gracular crystals
and they're often of course used in jewelry as well well you often get a lot of minerals
with a strong blue as well and this is a somewhat more complex
mineral many mineral compounds are quite complex and involve lots of elements
this is called linerite that's l-i-n-a-r-i-t-e the strong blue stuff
and it's from a a famous region well a mine called the grand reef mine a
famous region in arizona and it's lead copper sulfate hydroxide
so the strong blue is really coming from the copper content in this
mineral of which there are many many many copper minerals of course
and as a final one i'll show uh um here's a this is actually from school kill
township pennsylvania is an old specimen from the 19th century
this is a mineral called pyromorphite and you can see maybe on the they're
tiny crystals but they're tiny little barrel shaped crystals that are aimed up
toward the camera this is a lead chlorophosphate so it has lead and chlorine and and
and a couple of other little impurities in it as well and is an old old specimen and again
lead gives us often rich colors in the mineral specimens although you certainly
don't want to grind it up and put it on your cereal and eat it of course so it's a somewhat dangerous
uh element as many chemicals and minerals are but but they're beautiful things to look at and
as i've said before we know through spectroscopy of course that the chemistry in the universe is
uniform temperatures pressures other conditions change of course all over depending even
in our solar system but the chemistry in the universe we know is is very similar
everywhere in the is the same everywhere in the universe as far as we know so it's likely that on planets in many
many other localities throughout our galaxy and other galaxies you would probably have minerals that are pretty
similar to these on our own earth so those are the ones that i had to
share tonight and then only through shamelessness shamelessness eggnog by
scotty egged on by we talked earlier today
so i'll show my wreaths and stuff that i've been working on the book galaxies is out these are a
couple of my more recent books i'll be talking thursday evening into the astronomical league meeting if you log
on to it about galaxies and about all the things we've learned in the last generation about which is a lot about
the nature of galaxies uh this other book that i've done fairly recently with my pal brian may is a 3d book with
simulations with our good uh friend finnish friend jp mate mezzavinio this
great astro imager has produced these simulations in 3d what you can look at
with glasses of nebulae of the the clouds in which stars are born
and then of course astronomy magazine keeps me busy part of the time as well um and that is of course the largest
publication about our field in in the world and we're doing all sorts of things
going we had our first day back in the office together our staff in a year and a half
kind of setting things up and we have many many exciting surprises to come with astronomy magazine and
astronomy.com coming over the next year so stay tuned for that
that's another little jaunt into the world of minerals and and how the universe likes to make substances and
planets thank you scotty i will stop sharing my screen thank you
and back to you yeah i want to thank um i want to thank both
both uh you and and david levy for uh comments about uh you know our dear
friend carolyn shoemaker um i had you know i too had the privilege
to meet her and to know her and uh um i
one of the things that really struck me about carolyn was just how uh grounded she was but also how humble
she was you know she was at one time uh she held the world record for comet
discoveries uh she has hundreds of uh asteroid discoveries uh
attributed to her um yet um if if you met her and talked to her you
know she was not one to sit around and brag about her discoveries or any of that but she did
love the search and the hunt for comets um and uh
and and she loved uh uh doing astronomy i guess
from people that knew her worked with her david levy would certainly know this but she loved analog
work with the telescope she she liked looking at plates of film uh through her
stereoscopic uh blink comparator which would blink from one image to the other
allowing her to see uh you know tiny movements and the thing i think that was really remarkable about
carolyn was uh her sensitivity to you know you're just looking at a plate
that has thousands of dots on it and and uh to notice that something was out
of place or something was moving uh not really that easy especially you know
i mean if it was a really gross movement of course you would see that but it was the small stuff that uh really put her
in such a remarkable pace of discovery and um uh so you know we
uh i know that she lived for uh you know a long life 92 years um
you know but uh uh somehow i i still feel uh
i don't feel the loss as much as i feel the inspiration of carolyn shoemaker you know at this time she was always very
very inspiring to to all of us and of course so was gene gene was an incredible guy as well who
basically pioneered the field of impact geology he trained the apollo astronauts
he was basically the master of meteor crater who who figured out the science of what
impact geology was all about in in a refined way and and i can remember the
first time i met them i'd lost my mother in the early 1980s i was a pretty young new editor then and i remember the first
time i met jean and carolyn standing in the parking lot at lowell observatory
with david and with brian skiff there and they were immediately
you know as i said carolyn was very they were very warm very friendly you know i just got to know that you know they were
very much like sort of a substitute parents you know they were
very warm and friendly and helpful and i thought wow you know this is really what
great scientists are all about yeah these two it was really remarkable
oh goodness well i um you know i hope that uh uh that we learn
more about carolyn shoemaker in the days to come so because she was special to everybody
that that she came in contact with up next is
maynard pittendre from the astronomical league we've been talking also about the
virtual alcon event that's going to be happening this week starts uh on the 19th uh and uh
some of the speakers are with us tonight uh with uh david eicher and david levy um
but uh this is an event i know that uh the organizers are very excited about and um
uh as they put together this event it was cool because you know the astronomical league is the world's
largest federation of astronomy clubs they have they're climbing up on 20 000 members
and more members joining every day and it is uh
a remarkable organization as they're celebrating their 75 75th year
they have uh observing programs out the wazoo you know you can you can learn how to
uh just get started in astronomy through their observing programs and you can delve into specific programs to help you
learn more about the various objects in space and various techniques of observing uh the objects in space and
and they have an amazing uh uh
award program okay awards program uh of which uh the uh explore scientific is
now the underwriter of three of them uh so we we are the underwriter of the
national young astronomers award and the leslie peltier award and uh and there is
a new astrophotography award that we're getting involved in underwriting as well
so it's it's been a real privilege to be involved in all of that um i've been on
you know uh helping out where i am for the last i don't know 20 years or something so it's
it's been great and the astronomical league also is largely a volunteer group
you know so this is these people do it from the love of it and um so it's uh it's really great and uh you
know maynard is a an exemplary example of uh of the kind of people that are in
charge and running the organization um if you join the astronomical league you
won't be disappointed so i'm going to turn this over to you maynard ah thank you scott i appreciate it and thank you
for those kind words yes we have observing programs coming out of our yazoo
i've gotten uh 118 certificates some of many of which have
pins to go with them and uh and my goodness as fast as i can do them we
keep putting new ones out that are challenging and uh i just so appreciative of of you
that the new one that's uh you mentioned uh the wilhelmina fleming
uh award um what a what a great program uh that is and uh
if you know anything about the history of wilhelmina uh then you know why
uh her name is with that imaging award and if you don't know that name look it
up google it it's an interesting history uh i'm going to share my uh
screen and
there we go okay there was a little bit of delay there that caused me a little bit of concern there but it's good to
see it um and let me also say to to david
uh i appreciate so much the work of the astronomy magazine uh i was um uh
one of the original subscribers and uh my dad
uh trans we both subscribed after i went to college and he made sure we swapped
subscriptions so that i would have that continuing presence i hate to say it but uh cost factors
from time to time i used the issues in the library and i didn't honor my dad's desire to keep
that subscription going but what a great magazine uh and thank you uh david levy levi for
uh uh mentioning the the alcon uh that's uh coming up on uh august 19th
20 and 21 you said a lot about it i won't say anything more about it but uh if you
there's a lot of information on this screen so you might want to do a screen capture
of this but it is free and what could be better than that but you do need to register
and if you simply go to uh the astronomical league's webpage
astroleague.org you'll find uh you know out how to uh
uh um register for that uh we've got grand prizes uh explore
scientific is very gracious uh we've got a lot of other gracious things i can't believe
door prizes currently over 8 500. last time i looked it was a mere 7
000. now it was the point i was uh i was trying to make a little bit earlier is
how how the club came together to donate all those door prizes yeah certainly explore scientific did their part and
and and you guys have been very gracious in giving us that exposure but wow uh i it's the first time i've seen
astronomy clubs really come out and open the treasure chest like they have in this particular event so
yeah i tell you there's only one bad thing about these door prizes
as an officer [Laughter]
it's going to be a fun alcon and let me tell you i i'm retired but i've gone back to work
because of covid i i felt like i could be of use and so i've gone back to work but i'm on
vacation this week because i don't want to miss a thing of this uh alcon
and uh so it's gonna be a great experience one thing we always do with the astronomical league we give this
warning do not look at the sun through binoculars or through telescopes
if you are new to observing the sun do a screen capture of this page as well
because there's a lot of information on it but basically uh preserve your eyesight
and i've been observing the the sun for um 60 years now i started when i was uh
seven years old and uh and one of the questions i always ask my doctor do you see any damage from
observing the sun and no no not at all because i'm careful so we
want everybody to be careful okay let's get to the answers from uh global star party uh 57 on august 3rd
and uh question number one was how long does it take for jupiter to orbit the sun and
the answer is 11.86 years i would like to measure my age
by the planet jupiter my jupiter years yes what is the most common solid
in the cosmos and the answer to that is particles of dust
and why are saturn's rings so bright right now and boy it's a great time to look at
saturn and jupiter right now and the answer is opposition uh opposition is when the sun
earth planet angle is at its maximum for planets beyond earth uh when the planet
is on the opposite to the position of the sun so you got uh the sun and the
earth and then the saturn so it's it's close together basically so it's a
great time to observe this planet and if you've been around as long as i have you see those rings uh go through a
cycle of a little over a decade and flatten out almost uh
disappear sometimes they do disappear i think and uh now is a good time to start taking
pictures of of saturn every year to keep track of that now we had some correct answers
from uh star party 57 their names are listed here and uh so we congratulate them these
names will be added to the door prize list and now uh let's get to the questions
for global star party number 58 august 17th please send your answers to
secretary astro league dot org so um i usually get a drum roll from
some volunteer here bingo
okay question number one
how many of earth's robotic landers have landed or crashed
on extraterrestrial bodies in our solar system uh this list by the way give you a clue
we'll include gas giants moons comets asteroids any anybody in the uh uh solar system uh
answer number a apar letter a is 8 b
10 c 14 d 23
so send that answer by way of email to our secretary right now
question number two the moon has about one-sixth of the earth's gravity what is the gravity of
mars when compared to earth a 50 b 38
c 84 d 99
i'll tell you right now i'm living on the wrong planet whenever the doctor asked me about my weight
the astronomical league as uh scotland was saying we've got a lot of observing
programs and and they're absolutely great i i was going out for a while and
observing and just looking at the same stuff night after night after night
and the observing programs have gotten me out of the box and it's it's just opened a world of information but one of
our observing programs that's brand new is in our celebration of the 75th anniversary
this year and it challenges observers to make 75
observations of jupiter and different kinds of observations you can't just make 75 observations but all this is on
the astro league.org webpage you can find this uh new program and it's a lot of fun
i've been doing it and it's such a good challenge but here's your question
what are the four brightest moons of jupiter which are often called galilean boots now i'm not going to give you any
choices this time no abcd uh you're on your own but the only four
come up with these four and send your correct answers to uh secretary
astro league dot org and uh astronomical league
live number nine we'll be back on september 17th at 7 00 pm
and uh we invite you to that we'll have a guest from uh astronomical adaptive
optics and uh and and again don't forget about al time
uh if you've never been to an alkyne this is a great time to go to your very first one
we have great speakers scott i appreciate the opportunity to be
here with you and uh we always appreciate your support and it's great to be with these august
people i'm i'm always humbled by the fact that i'm with uh folks like the rest of the team here
you are uh you know i i wish that uh i had met you uh
and observed with you years ago mandar you are uh definitely um uh a great
person in this community so you know thank you very much for uh being on our program tonight thank you scott and
thanks you know for the support of the astronauts back up with told david uh about observing i have fun wherever i
go and that certainly includes where i go with my telescope well man one thing that i wanted to add
just before we get into the next uh speaker is that when i
and i'm certainly not going to uh because if i give too much detail in this little story i'll give away the
answer to your question so i'm not going to do that the first thing i ever looked at through a telescope
was on september the 1st 1960 and it was of jupiter and those four
mysterious moons and all i can say is galileo himself could have felt no
greater thrill than i did that night to actually be able to look at jupiter
and eventually to discover that there were those moons going around jupiter maynard thank you
so much and i thought that david's talk was very very good i really enjoyed it
i'm looking forward to the rest of them me too me too
okay well great okay so up next is um sabella burlingame
sabella is um attending uh elementary school she is uh
11 years old and um i i believe you're 11 years old maybe maybe you're 10 years old but i i uh
maybe i've got that wrong sabella um but you get you you give a wonderful
presentation uh and we look forward to your presentation tonight
okay can you guys hear me all right yep okay good
and i am 11. of that background thank you okay let me share my screen
okay i need a way too
ah okay um [Music]
i go back to what you had and then you can um
let's see i think yeah that's big present button up in the upper right
yeah i'm presenting but um oh is it just showing on the other screen
uh there we go i just had to it was still showing you guys so i had to move you guys out of the way ah
yeah okay there we go so do you want to see us guys
okay so you don't want to see these guys just kidding
um so my topic tonight is the wright brothers um as i hope all of you guys
know they invented the first airplane
and flew it so is it gonna go
so um wilbur and orville wright the wright brothers they flew the very first
airplane um actually orville did and his brother stayed on the ground in case if
anything happened the first flight lasted 12 seconds and covered 120 feet that's almost half of a
football field so that's pretty large distance for the first flight
and wilbur was born on april 16 1876 and died at age 45 in 1912.
orville was born on august 19 1871 and died at age 77 in 1948. they both
grew up in ohio even though orville was born in indiana
so something something i would like to just kind of interrupt here a little bit uh
i am i was also made aware that you are related to one of the wright brothers is
that uh um is that uh you're you're like a
uh a sixth cousin or something is that correct yes um
so my great-grandmother uh jane wright was uh related to them they didn't have
the wright brothers weren't married so they never had any like direct descendants after them so
cousins yes wonderful okay that makes this uh this presentation all
the more special thank you yeah and um if i go back here um
yeah orville's birthday is um august 19th which is coming up in a few days so
that's another reason why i chose to do it right okay so what inspired them to fly
in 1878 their father milton wright brought home a rubber band toy powered
helicopter that's this picture right here um this is one of the main things that
inspired them to fly they were also fascinated by birds and bats the wright brothers flew the first plane and
designed it too during the winter of 1901 to 1902 wilbur
and orville built a wind tunnel and conducted experiments to determine the best wing shape for an airplane
they said they wanted to fly for fun and use the funds and use the funds for even more
scientific research little did they know that they would change the world forever
it's kind of interesting because their real intention wasn't to actually like fly and change
the world forever they were just have fun
yeah oh that runway there we go the designs the plane was double layered
and was controlled by using a hip cradle which the pilot controlled by sliding his hips from side to side the cradle
was connected to the plane's wingtips with wires the cradle was also connected to the rudder which controlled the
plane's yaw rotation around a vertical axis it took them an entire four years
to build the right flyer long time
so why did they choose kitty hawk the brothers began their experiment in flight in 19 or excuse me in 1896
at the bicycle shop in dayton ohio they selected the beach at kitty hawk as their proving ground because of the
constant wind that added lift to their craft in 1902 they came to the beach
with their glider and made more than 700 successful flights
who else was there there were only five witnesses on the beach during their first flight and by
the way all of them died before um we landed on the moon sadly
in fact most people in the us didn't believe in the wright brothers but when they went to england they got a lot more
intent they got a lot more attention and many more believe believed in them too
i did some research and found out some famous people that were alive during the first flight and the first moon landing
these include colonel sanders the creator of kfc kentucky fried chicken uh
charlie chaplin famous silent film actor and agatha christie famous
famous british author he's in space
most of you know that a rover called perseverance recently landed on mars and
has a helicopter on it nasa has been running tests to see how long the helicopter ingenuity could stay
in flight for but what most people don't know is that nasa actually put a small piece of one of the right flyer wings
onto ingenuity it's located under the solar panel nasa also named the first
martian takeoff and landing area for the 2021 ingenuity helicopter wright
brothers field there was also a similar similar artifact that is on the moon that was
brought there on apollo 11. so they were both from the wings of the
wright flyer the effect it had on the world wilbur
and orville had no idea at the time that 70 years later humans would be flying into space and even landing on the moon
and even landing on the moon their designs changed the world forever and now we can travel across seas without
any boats needed even though the planes evolved over time and look totally different
if you are ever flying anywhere just remember that just remember that it was made possible by two brothers
yay that was a great presentation sabella
thank you very much thank you very much the uh of course i think all of us that
are inspired by flight and space flight in general are you know are
find the wright brothers story inspiring and when i heard about that you were related
i was just the excitement that ran through me was uh was quite intense so i'm i'm i'm
really happy that you decided to give that presentation tonight uh that's that's wonderful
isabella could i could i uh mention a quick story
about her talk sure is that okay that was a great talk and
thank you for giving that and it's an honor to meet a cousin of the wright brothers and bear with me i want to tell
you a quick story if i can here because my father john eicher who got me
into this chemistry and mineralogy while i was interested in the stars some of you knew him david you you knew
him well um he grew up in dayton ohio which was our ancestral home since the 1850s
until i came along and lived on ruskin road and two houses
down on ruskin road from him lived a a woman who this was when my father was
young in the 19 late 1920s and 30s she lived there her name was ivanette wright miller and she
was the niece of the wright brothers two houses away from my father
and so she knew my dad well when he was a young kid your age and up until his
college years and every once in a while this was wilbur was long gone by this time of
course but every once in a while orville wright a black uh a big black ford would
pull up there in the neighborhood with acetylene lights on the front of it
and it was orville right and and my father would talk to him so here my
father died uh five years ago at age 95
so he knew orville wright someone who lived up to your time
and his favorite story about orville who talked about lots of things in flight
he he had all sorts of correspondence and his niece ivanette uh had in her attic
all sorts of the correspondence which had been given to her and that house is still there in dayton
um and my father in those days was a stamp collector something that is not so much of a thing anymore
but um she ushered him up to her attic and and said pick out a really
good envelope you'd like to have for your collection and i have that envelope upstairs i'm not going to run get it now
but i have that upstairs in my house here and it was an envelope addressed uh to
orville wright from jimmy doolittle the great general in the second world war
who led a raid over tokyo and so on and
being super conscientious always regretted this telling this story
he pulled out the letter and handed it back to mrs miller and just took the
cover but can you imagine what orville wright in in 1932 would have been
writing what jimmy doolittle would have been writing orville wright about you know my
god in the early 1930s so that letter remained in the right family but i have
the cover in my collection now and there's someone who was up through
nearly our time here who knew orville wright so you think of these things as
impossibly long ago but it was just one human lifetime ago here that he was around
your cousin there so i thought i'd interject that story oh it's wonderful
yeah yeah it is amazing what was accomplished in really such a
short amount of time one thing i would like to add sabella is
that you have mastered one of the things that very few of us have even the us older people
and that is you've mastered the art of making a presentation that had everything in it and kept it short
and uh it didn't go on and on and on and it was beautiful and well done congratulations
good work sabella thank you
it's it's good to be something as uh as a i'm a southerner and not only a uh
uh an astronomer i'm also a presbyterian pastor and a southern storyteller and
and david's right i can go on and on and on you were fantastic i tell you perfect perfect
presentation nice and brief there and everything included and boy i'm impressed by uh david once
again before my presentation and now uh i tell you
none of my ancestors knew anybody
you might be surprised maynard so oh that's that's wonderful that's great
uh i'm really uh you know this is a very special global star party so and sabella
you really contributed to that um as well so thank you thank you
um up next is adrian bradley uh adrian has
uh has wowed us with his landscape photography his night sky photography um
uh you know we're very pleased very happy that he enjoys being on global star party and contributing as he does
um and uh you know he he warned me he didn't have a lot of
of uh imagery uh uh regarding the moon but um
i think he probably has something uh that uh will fit into this global star party anyway so
adrian i'm gonna turn it over to you man all right so i am kind of like uh
cameron today i'm in two places at once um and after that wonderful
presentation by sabella i'm under pressure to keep this uh short and moving along so thanks a lot
for that sabella thank you um but at any rate so i do have an image i
recently took a moon image but unfortunately did not upload it um attempting to discuss the
lunar x and v which is for a photography um fanatic that's something that you try
to shoot at on our own moon it's a it's a feature that's caused the lunar x uh is a part
of the werner crater and there is a amare that has
a mountain ridge that consists of lunar v um
but i do have some other things and i will share my screen from the presentation layer which i'm calling
my other entry into the uh zoom meeting and here they are
i went out and saw perseids um for those of us that got a chance to see anything
in the skies that you were in um there you there were perseids this year
i went to a darker site and i was very impressed at um i shouldn't say impressed because the
sky always impresses no matter whether it's clear cloudy but um
i was awed at the number of perseids i was able to see i was with a good friend
of mine uh dr brian adam who's also a fabulous astrophotographer before i show
you some of those images which you're seeing some of those i wanted to share
as far as moons go and end theme with um
the uh presentation this was when jupiter and saturn were were at the position where they were
both in the same field of view and one of the challenges was to actually show the light
of their brightest moons as well as the planets themselves this was my feeble attempt to do so
plenty of really good astrophotographers nailed this i used the telescope and this was as good as i can get one of
these is actually a star i believe it's this um this has a long license plate of a
name the rest were actually uh jupiter's moons we were joking for a
while jupiter had five bright moons but in fact it was a fourth and that
there just happened to be a star that lined up um with the uh plane of the other moons
so one of the places yeah the five moon so one of the places i
went was alcona it's a county park it's a beautiful place and these are some previous images
that i took of um of alcona park it's quite peaceful and
it gets dark enough i'd say a bortle three and um the milky way shines really well
here well we just got out of smoke a smoke-filled um
sky so i went back and took some more images and this is
this is one of the images that i took with a regular stock camera that shows you there's a lot of stuff in here the
double cluster peeking through clouds oh yeah and you see some meteors here
the perseids were all over and um i actually had to process this image to
get these but you can see these faint some of these meteors you wouldn't see unless you went to a dark sky some of
you may not be able to see them on your screen but in my big computer screen i can see them
um there's andromeda there's m33 the light from m33 your double cluster and
your heart and soul nebulas are here there's plenty of things in this wing but not a lot of
milky way imagers shoot at this part of the milky way at least to my knowledge most of what you see
with the milky way shooter is toward the core and there's bright i i believe it to be
a bright perseid because it's coming in the exact opposite way that we were just facing and it's streaking through the skies you
know meteors can come from anywhere um some of the uh meteors were talking
about um the moons and moonlits um
as far as far as asteroids go and then of course the perseids being the um
remains of a comet i believe comet tuttle and all of these fragments can come you know they come to earth almost
every day but during the during the perseids they stream in a lot more um a lot more particle stream
in earth and you can see them the darker the sight the more meteors you can see and just about every picture i took i
had a meteor in it somewhere so i'll quickly share some of these
sometimes you get something like parallel there's a faint meteor here and then there's the bright one
this tree does grow like that it's a very interesting tree so it made for a very interesting foreground
um in a lot of these shots here's a portrait view where i had more meteors almost every
shot it's what you want when you're when you're doing some imaging
and the goal is to catch meteors now you may ask why didn't i just do a time lapse and you know i'd had hundreds of
uh meteors if i had to just let the camera go to one spot um i'm gonna work on that so
it's uh i generally like doing stills but i am going to get into
um just letting the camera you know taking a bunch of images stacking them together
as it is i've been doing hdr um stacking lately so it's been something i've
enjoyed doing um there's another another meteor coming through there's jupiter
and there's saturn the stacking process wasn't too kind to put a hole through jupiter
so we'll be working on that the overall image the milky way look nice but um
working on overall images it's always a work in process then you pick up the camera that's
uh fully modded and then you get all of the detail from
the aha regions that are here so you see the heart and soul you can kind of see their shape
all of this stuff is in the milky way and it makes milky way
photography come out a lot more there's a lot more to see when you can
use a camera that has all of the filters off stock cameras are good but um
cameras that are made to shoot to allow hydrogen alpha to come through will allow
more light from that spectrum to show up in your images and there's m33 again there's the
andromeda galaxy m31 cassiopeia is in here somewhere i dare
you to find it and so is perseus which is the uh where the perseids the radius of the perseids is from one bright first
he had photobombed my image here but nothing wrong with that and i think even this last one
the cygnus region where we've got the north american nebula here the seder region
vega and a faint little perseid at least we believe it to be a perseid i
i would ask david levy at this point because i do believe the aquarids are also active at the same time and so
those meteors would streak in a different direction and this one appears to be doing so it's it's more
horizontal than it is vertical which i would expect for perseid so
i wonder if this is actually an aquarid that um that we're seeing here so
so that's it just a few few images of the mini that i took
um i'm always happy to get out into the uh night sky and image
one of the things that i prefer to do is just look up i before
even setting up any equipment whether i bring them small or i try and go all out with
larger equipment i usually like to just sit there in the stillness of the night and just look up
and that's where i get some of the ideas for what i you know what i want to shoot at or
what i'm seeing and i compose it in my head before i actually
set up the camera and um it's like phone call so it's someone telling him
to tell me the presentation's over so i will in there thank you all for
um watching and um keep looking up there's always something
there whether it's meteors or anything else the night sky has to offer
that's right adrian there was a there was a question on how how
are you getting your images you know uh you're really wowing the audience with
your milky way shots and and your captures of the perseids is that do you use basically the same
exposure are you using different exposures i use i've started using different exposures and combining them i
use lightroom photoshop [Music] and so i guess the long story short is the
process is to take successive images i have a tracker so the image is at least
30 seconds and it's moving at a speed that's half the speed that the sky rotates and what
that does is your stars and you know molly's uh nodding your head your stars
are he does this stuff too has some amazing images um
the uh stars will steam around your foreground doesn't blur out as much as
much i said yeah the darker the sky you instead of having to take
two images and merge those together you can take a single image but what i do is i take three or more
at different exposures so like i'll take the iso down iso on a camera um
you know similar to the uh gain um on the on an astro camera so three
different so like one that's it's a little darker fact i may be able to show you
how one of those pictures came together i'll quickly share a screen again as soon as i find that button
share screen one so here's here's an image i just put together
um i'll look for the image that i loved the most was this um
there's another one over here yeah this image i
love this image putting it together was a matter of
putting together three different images at once so
let's see so here like this is a single image right here there's a single image
and if i'm lucky i so i took a couple of those
and if i'm lucky i'll find the image that had the meteor in it there it goes this is the single image
that had the meteor in it we both saw this meteor and we were going oh wow that's great
and so what i did is i continued on taking more images there's the low there's the darker
even darker and i think i even went yeah so i went even darker than that i combined a couple of those images
and ended up with this compo it's like a composite but it's more of a stack
there's the meteor and there's the combined three images and what you get is more
range so i've got a little bit of the foreground visible and it's a lot brighter
then i take it through photoshop to run a couple of routines to bring out the milky way and that's how i end up with
this sort of image so it's a bit of a process um but it's a i've i embrace it i love
doing it it's it's how i'm doing my landscape images to make them brighter
and get them uh get them coming out you know where where they're visible
not only on a big computer screen but you can take your smartphone and you can still see the details of the image on
your smartphone so hopefully they would like to have questions if i could adrian yeah you
were asking about other showers and the delta quadrants are still active but they're more active
before the persian maximum than they are now there's also the kappa cygnids which
really were active around the just before the maximum i saw a few of them
and then the night before last last time we had a clear night here i got two meteors from the alpha
capricorn shower which should be active earlier but uh they were late and so they're
active now and so i'm very sorry about that but um we'll have to send them a parking ticket
or something but anyway yeah good talk thanks sage thank you
adrian i have to tell you that uh my first astrophotography uh effort was comet to kia segi which i
think was 1965 and um so my my dad taught me how to uh
use his dark room and and this photograph does somehow show up on the internet from time to time and if
you look carefully you can see my fingerprints on the negative and and i i thought that i had improved
somewhat when i went when i look at your artwork i think i haven't gotten any better since 1965
you are amazing adrian this those are just fantastic pictures
well thank you i really appreciate that it comes out of a well one there's a passion for just capturing the sky the
way i see it and then the other passion is i come from an astronomy background
and um the the starry night is not just there to be a pretty picture
to you know to highlight a foreground and i do like shooting over water
um the the night sky it's is there itself and a lot of times it's it's part
of the subject so my approach to it is treat the night sky as
the main attraction and earth is its frame and that that's how i approach it so
they so the images you know they come out they're not there you know you don't you don't have i try not to
blurt out as much you know i try to make sure my focus is really sharp uh when i start and i take a few test
shots there because it the sharper your the sharper your uh shots the more
detail of the night sky you can pull out and there's still a lot for me to work on and learn too i've got some artifacts
in there that you know it clean up and and i've got a lot of great astrophotographers that um
have helped me along the way too so uh it is a community thing so what you see represents those
that have done the work you know you know folks that have uh encouraged me as it go
along so i definitely uh appreciate the kind compliments that i'm
getting um and uh my goal is to just continue doing it
and uh continue just trying to share what i see out there ain't that what i see usually
makes the images pale in comparison to you know what uh you know when i'm looking around
and um the goal is just to try and share that in the best way possible so thank you
great right now we have a comment here that somebody would buy a book of adrian's images that came from american
meteorite fans so uh you might consider doing that that's great i am going i am working on that
i'm going to officially take images that i love and um also looking at putting up another
website too because i know some people are interested in prints i'm actually going to have a large print available
um of one of the milky way shots that i've taken over the years and um so that'll that'll
become available and yes i am i have been asked about putting together a book and
i will uh i will try and curate one another that's great
get right on that yep okay well up next is uh is molly wakeling uh
she conducts when she appears on our program she conducts something called
astronomy's universe and uh molly's combination of you know her
blend of science and uh the beauty of her astrophotography
uh just really makes for i think just an unforgettable experience and
um molly is also someone that's you know full of enthusiasm and always helpful to uh you know people
who are just learning or you know people are quite advanced you know she she knows quite a bit of about image
processing image capturing uh you know almost every aspect of uh of what an
astrophotographer goes through uh but uh she dies in deeper gives us the
nuts and bolts of how the uh you know the these objects work uh
that she's photographing and so we always love having her and uh molly will
be on i think saturday uh with the uh uh alcon virtual event as well so
you know if you're if you love what you see tonight you're definitely going to want to tune in on saturday and watch your program so
molly i'll turn it over to you thanks scott um i'm not presenting at alcon i'm getting an award so that's
that's what you're getting an award yeah actually never parties
i said forget it they've already sent it to you but uh
what are these years old you are getting you are getting one of the astrophotography awards that's yeah
that's great wonderful wonderful well an early congratulations
thank you but i'll be there with you since we're broadcasting the event so awesome yeah yeah i'd like to give a
talk at alcon some year and that'd be cool i'm sure you'll be asked at one point so
all right all right well i'll go ahead and get my
slides rolling here there we go you should be able to see
those all right um so uh thanks again scott and i love
coming on here when i can phd schoolness keeps me pretty busy but
i try to get on here like every other week or so um so glad to found here again tonight i
know the theme for tonight is moons and moonlets but the only moon i've taken an appreciable number of photos of is our
own moon and um i think we we know a lot about that and
probably talked about a lot today tonight so i decided to take a completely unrelated object
of by messier 31 the andromeda galaxy and uh what i like to do for these
presentations is all the pictures in them are my pictures with the exception of the one on the on the first slide
here uh well the not this slide but like the first presentation slide the next slide where i usually grab a nice hubble
image of it um because it's nice to have humble images and talks because they're gorgeous and
awesome and yeah okay so uh yeah message 31 they dominate galaxy
much loved by astronomers and people who love astronomy all over the world
so what is the andromeda galaxy it is a barred spiral galaxy it is known as mestier 31 on part of
charles messier's catalog of things that are not comets although they'll be a pretty large
comment if it were one also in the new general catalog as number 224
it is the closest major galaxy to the milky way i say that because the magellanic clouds are considered
galaxies but they're considered to be dwarf galaxies and um when we talk about
galaxies that are closest to the milky way we tend to talk about like galaxy galaxies not like the baby galaxies that
the dwarf at the um magellanic clouds are so where can you find the andromeda
galaxy if you've never looked for it before it's not too hard to find especially you've got a pair of binoculars and you can just kind of rove
around this part of the sky but if you look for the familiar w of cassiopeia
and also look for um oh no i think it's square of pegasus is
that the right one i'm really bad at constellations guys it says yes it is
there's a couple of squares up there and this particular one is this pegasus uh there's a really bright a well
relatively bright star in the corner of pegasus known as alpherat and i usually just kind of look between
alpharets and the bottom kind of right star of the cassiopeia w
and draw a line between them but go below it a little bit there's a better way of
course which is star hop a bit from uh from afarats out to a couple of other stars in what appears to be either the
wings or the legs of pegasus uh and then hop up to the andromeda galaxy from there
but uh for the casual observer i just kind of like go partway between uh the star of cassiopeia and now
ferrets and then kind of hunt around until i stop that's exactly what i do
and you will stumble across it yeah or if you're in a portal through sky or better you can just see it yeah
you can see it naked eye and that's really cool to do or even if you're under light pollution you can
usually see it with binoculars unless maybe you're in downtown chicago or something like that but it is quite
bright so that's where it's at from our perspective here on earth where is it in
relation to our galaxy i'm not sure if any of this text is coming through very
well but um the red label here is our galaxy and over here on the bottom left we have
the small and large magellanic clouds and some of the other dwarf galaxies that kind of surround the
milky way and off over here to the right with the
yellow arrow is the andromeda galaxy and it's got two other messier galaxies
beside it m110 and 32 and um then over here is the triangulum
galaxy m33 so you can see it actually kind of forms a triangle in that way with i just noticed
between the three of these and some other galaxies kind of in our our local group
here but um from a uh kind of a larger universe perspective
this is kind of the layout of our little local neighborhood so some fast facts about the andromeda
galaxy it's in the constellation andromeda would never have guessed
it's about two and a half million light years away which is a long distance but is
very close on the intergalactic terms it's the again the closest major galaxy
2s fall closely behind by m33 at about 3 million light years
um usually for a lot of these objects they can they've been discovered
was actually discovered by somebody looking through a telescope because a lot of a lot of astronomical objects
aren't visible to the naked eye for anybody who didn't have a telescope but in this case andromeda was probably
known to into antiquity because of its brightness and how large it is on the sky but it
was first described it was first written down in 964 by a persian astronomer
probably not going to do this quite right but al-sufi along those lines
and and subsequently re-observed by many others thereafter
and again probably into antiquity has an apparent magnitude of 3.4 which is very bright among astronomical
objects although it is rather large on the sky it's about the the area of six full
moons even though when you see it in a pair of binoculars or with the naked eye it appears a lot smaller than that that's
because we're mainly seeing the core of it when you look at it with uh with the even with a telescope most of the
time has a diameter about 220 000 light years which is about twice that of the milky
way from recalling correctly and it has something on the order of a trillion stars which is about i think about 10
times more than the milky way has so it is considered to be the largest galaxy in the local group although
there's been some new measurements recently suggesting it's actually physically smaller than
we've or no has sure stars one of the two uh that is less massive than we thought originally but i think it still
kind of takes the cake in our in our it's the big the big guy in the neighborhood if you will
yes so uh the andromeda galaxy is one of my one of my favorite
astronomical objects from a historical perspective because it is responsible for widening humanity's view of the size
of the universe originally when it was being uh observed and catalogued by
kind of the foundational astronomers of the 17 18 and 1900s it was considered to be a a spiral
nebula within our own galaxy people could kind of see some of these dust lanes and some of that spiral structure
but uh there were many such spiral nebulae observed and this one was just a particularly
large one it's estimated to be about 2 000 times the distance to sirius or about 18 000
light years initially in 1912 vesta sliffer used spectroscopy
to measure its radial velocity and came up with a value of 300 kilometers per second which was the largest value yet
measured of anything that had been measured in our in our own galaxy uh so it's kind of the first clue that
something might be up with with this particular this peculiar andromeda nebula as it was called
in 1917 astronomer pepper curtis found that there were several he saw a nova
which was actually a supernova but it appeared very dim so they called it a nova and he spotted several others on
that are very faint on photographic plates and based on when we see nova in our own
galaxy and they're so much brighter than the ones that we were seeing in this andromeda nebula yesterday there was
actually much farther away that it was a lot farther away than the other objects in our galaxy
and was it became a big proponent of the island universe hypothesis where um it's
kind of the size of of the whole universe to humanity's mind uh was uh
once we started kind of looking out towards space was that the milky way was pretty much all there was um
but in the early 1900s people started realizing that maybe there's some other
things out there we don't really know what they are in relation to us then in in 1920 there was the great
debate between curtis and harlow shapley about the size of the universe was
this spiral nebula inside of our galaxy or this island universe
and the debate was finally settled in 1925 when edwin hubble observed cepheid variables in andromeda
on photographic plates and cepheid variables are a very interesting type of variable star where
the internal dynamics of the star are what's causing its change in brightness and
the the period of the change of change of brightness over
hours or days or weeks is is very closely coupled to the in the
absolute brightness of the star so um i don't know the exact relationship but uh brighter stars have
like a star with with you know such an absolute magnitude has a period
and every cepheid variable that is of that brightness has about the same period and looking at the cepheid variables
that are in the andromeda galaxy they were far dimmer even though they had the
same periods as much brighter cepheid variables here in our galaxy so that was
really the the nail on the coffin on this being a nebula in our galaxy and it
actually being another galaxy that is quite far away further away than anything else that had
ever been measured i'm sorry if you can hear my cat in the background he uh
singing the song of his people
so i wonder if i talk about andromeda at star parties especially when there's kids around
i love bringing up the fact that the milky way and the andromeda galaxy are
eventually going to collide m31 is moving toward us at a speed of about 68 miles per second which is like really
fast in human terms maybe not quite that fast in astronomical terms but it is moving toward us it is blue
shifted and has very little sideways velocity so it is coming almost directly toward us
uh or you know probably in reality a combination of us moving together but since there's no
uh there's no absolute reference frame in space you know you can put it whatever terms you want
um so uh when the two galaxies do collide they'll likely merge to form an enormous
elliptical galaxy because uh it's gonna take a long time for that structure to kind of settle back down after this
crazy uh gravitational chaos that happens as a result of the two and when two galaxies
collide there's no there's not usually almost so i think there's pretty much not any
real collisions like there's no stars that are slamming into each other or planets colliding and that's entirely
because space is big like really big like the distance between stars is enormous
so i there's extremely little chance of any any actual two stars uh clouding
with each other or even really getting appreciably close to each other a little bit a lot of gravitational interactions but no actual collisions
uh of course now the the the black holes at the center of our galaxy and the center of the andromeda galaxy will
likely merge at some point as they um they're then when they're strong gravity kind of pull toward each other um but
even that's kind of uncertain and there is a small chance that the solar system in all of this gravitational chaos will
be ejected from the system so i like from the new
milky way andromeda hybrid so we could just be flung off into uh intergalactic
space of course by the time this all happens uh humans will probably be long dead or evolved or maybe we've
discovered the mass effect generators and can travel to other galaxies
yeah it's fun to imagine so i'd like to show what
a lot of these objects look like in other wavelengths besides optical besides what we can see with our eyes
and with sort of normal human vision style cameras
and i happen to find this nice graphic showing the andromeda galaxy at the same
angle in each one of these in several different wavelengths so starting with radio radio tends to be pretty low
resolution because of its very long wavelength so you kind of see these blobs and smudges and kind of the
but some still some of that ring structure which is really cool a lot of the emission in radio coming from
andromeda is owned from any galaxy really is from hydrogen gas
it has a strong radio emission on the 21 centimeter line uh and some others as well
uh so we have you know you can see the microwave and the infrared ultraviolet and an x-ray x-ray tends to
be just a lot of point sources like um uh pulsars or the core with its i think
just actually i think i was just reading that there's actually several black holes in the core of andromeda which is
super cool and also a compact very compact star cluster or something along
those lines um i started reading a paper about the the radio a new radio image that came
out literally i think just like last month but it was a 33 page paper it was quite exhaustive and i decided not to
include a lot of those details in here although it was quite interesting
um yeah so this is what it looks like in different ways let's have their own and in pretty much everything except for
optical you can really kind of cut through the gas and dust that surround a lot of
the stars and just a lot of the space in the andromeda galaxy and see more of that spiral structure and kind of what's
going on in the interior so finally uh observing the andromeda galaxy the best time of year to observe
it when it's up in the sky is in august and february and uh of course when you get more into
the winter it's up earlier in the evening if you really don't like staying up too late waiting until later in the
winter to see it is good but then of course you're cold so it's kind of a balance between how that you want to stay up versus how cold you want to be
it's pretty far north so a lot of southern observers may not be able to see it or it'll just be above the
horizon depending on where you're at it's visible as mentioned earlier as visible naked eye in uh even even
locations that are not that dark you can often spot it if you know where you're looking and when it's dark don't
just kind of stumble across it in telescopes and binoculars it appears as a fuzzy blob
if you have a larger aperture telescope or go out to darker skies you can make out some of the dust lanes
around the core and uh recommend using your lowest powered eyepiece because again it is
enormous the size of uh the area of of six full moons so it's
enormous on the photographic side uh you need a pretty large field of view to capture
the whole thing or else you need to mosaic it so camera lenses are really good here or short focal length
refractors for forgetting the andromeda galaxy it's actually deceptively difficult to
image to start being such a popular object to look at and being so bright that's because the core is a lot
brighter than the edges so you have to take you should take multiple exposure times in order to get
both the core and the outer edges similar to how one would image the orion nebula
and i've taken 19 uh iterations of like sets of images of
it and i've never been really satisfied with any of them so just despite it basic divide object it's
it's very difficult to image it's best done in wide band color so red green blue
and but you can add some hydrogen alpha data to it as well because there are uh like most galaxies some star forming
regions in there that can add some nice detail and depth to the image
so this is image number 19 the latest i've taken back in uh in the fall of 2020
um i am so not this is my favorite of the ones i've done but still not totally
happy with it i got some weird color gradients but it kind of makes for a cool artistic image so i brought those out a little bit
took this in my backyard in berkeley california so under under some pretty decent light pollution
uh with my zwo 294 color camera and a light pollution filter which is
essential if you live anywhere near a city this is all my selection avx this is right before i got my ioptron
mount and it's a little under eight hours of data about an hour's worth of minute
long exposures for the core and then um the rest being five minute exposures to
get the rest and i didn't i didn't uh layer these like high dynamic range i
just stacked all of them together and then uh applied hdr multi-scale transform in pixel sight so i was able
to kind of keep the core from blowing out in that way um but yeah that's what i got
excellent yeah uh celtic raven uh says wicked image with
the stars being consumed by a black hole when you think about it you know to me when i was looking at this image molly
it looked very three-dimensional you know so great job wonderful thank you
all right well thank you and thanks for again coming on to global star party molly i know that you have a very heavy
schedule with your school and and all the things that you do so and i i
personally want to thank you for all the great outreach that you do you're a great ambassador
in our community of uh public education and astronomy so thank you thanks a lot i may not have
put that presentation together like two hours ago
be impressive very good it was a great presentation i just whipped that thing out
it looks like you follow it looks like you follow a really good template as far as how you do your
presentation so i see how you could you could easily get that um with doubt
yeah i've kind of kind of developed the template over these first couple of shows and it does it does make the
creation of it go a little bit quicker yeah yeah well that's that's a great way to do it
mine's basic find some images and talk about them so so i could stand to use a template like yours uh as i keep doing
these sort of things so excellent work as always thank you keep going free for him adrian
it's more fun
you're allowed to do that on global star party you know so exactly that's what i do so
that's what i do all right well up next is kareem professor kareem jeff jaffer from john
abbott college uh he is also an outreach ambassador
he is working with the royal astronomical society of canada's uh montreal
it's the montreal uh montreal century yep center that's right c-e-n-t-r-e okay
which sounds so cool uh the santre
that's right that's right um and uh uh
kareem's presentations are always uh very interesting uh you can see his
uh presentation style is uh really quite polished but also very it makes you feel at ease
which is i think really part of the secret of a great teacher because he makes
it makes the students feel at ease which uh allows you to dive into the subject
matter you know and so it's uh and yeah i've mentioned this before even the pitch of
your voice um uh guides you into the subject matter as well and uh that's a real talent and uh
so i'm glad that you bring that on to the global star party uh green thanks scott as long as i'm not putting you to
sleep because that's gonna be no you're not putting me to sleep not at all not at all and you are giving a presentation
right uh yeah the astronomical league conference okay so i have on friday i'm going to be talking about two-eyed
seeing which is uh bringing ancient and indigenous astronomy together with modern astronomy and looking at objects
with both sets i'm hoping i'm hoping i still have to
put it together you know i'm i'm on molly's side i just finished this one two hours ago you go on and then put it
together it's the best way to do it because then everything is not only fresh in your
mind but it's also all current and up-to-date and that's one of the things i try to do with teaching right you gotta if
something happens in astronomy you wanna bring it into your class you don't wanna have everything finalized a week before that's right that's right you don't want
some major discovery to blow away all your uh your information so exactly so tonight a
texas star party in 2018 i was giving a talk on nucleosynthesis
and a new discovery had like just come out the month prior about uh
how some elements get out of neutron stars so it was really funny
oh no wonderful all right so tonight i wanted to chat with you about sketching the
moon and i'm going to talk about this both in terms of an outreach tool but also in terms of something for amateur
astronomers or professional astronomers to do when you're at the telescope so i'm going to talk to you about both
sides of it but before i do you know we've got our weekly check in with the rasc
so the rasc national has just recently restarted the insider's guide to the galaxy show you can find it on their
youtube channel and today was actually about the giant planets which is a lot of fun and then since we're talking the moon
tonight i want to remind people that there are observer certificates at the rasc as well and adrian has just
recently joined and i hope he's going to be getting a bunch of these certificates it's time for me to work on those yeah
we had one of our members uh just yesterday talking about the fact that he's a few
a few uh messier objects away from the whole messier certificate and it's been a while since somebody in the montreal
center has gotten that so we cannot wait till he finishes so thomas if you're listening we're all behind you 100
and then our sky news magazine it's uh our canadian popular astronomy magazine
and the most recent issue july august i'm proud to say two of my students are
published in here talking about their their journey into citizen science so
you talk a little bit about learning a bit about xenoverse and diving into a couple of those projects on page 33 and
34 if you do have your own copy of sky news but for our local montreal center our
big news is this past weekend we got to be under the stars with people it's been
a long long time so we were very careful we all
had masks every station only shared their view using screens and that was something we
were very careful about but the upshot of it is it means that we actually have the images that we were
showing the public with us so we have on the left here we've got from david schuman one of our exec he took pictures
of jupiter with the moons he took pictures of saturn's rings and he took picture of the moon and shared that in
live time with the audience in beaconsfield we had another member quatran who some
of you will remember from the international astronomy day program he did wonderful star trails at the beacons
field skyline and then in the bottom right there you can see a bunch of us sitting on the lawn and i'm relaxing in my lawn chair
while i'm using the ev scope and we were able to pull up multi-minute stacking of some of these
nebulae in light polluted skies to share with the students and explain to them
what gives the nebulae their colors their lanes their shape etc it was it really was a powerful outreach tool
the other big thing we have going on in the montreal center is our annual keynote lecture and david has been our
lecturer in the past several times for the townsend keynote this year it's going to be elizabeth howell and
elizabeth howell participated in the mars society two-week mars simulation and so she's going to be talking about
the art of isolation during a mars mission and because we're still being very careful with lectures and with
public events we're going to keep this one by zoom so anybody can attend so it's bit.lee townsend 2021 so if you
want to register please do we'd love to see you as part of this our keynote event of the year really is
one of our top attended public events i'm also part of the astro radio reach
out and touch space panel and i was talking to david eicher about it earlier today uh in our recent show we actually
highlighted the big world record attempt happening in mid-september in the uk where mark
thompson is going to try to go 140 straight hours lecturing astronomy and
not only that he's going to be monitored for sleep deprivation as part of a study
on the effectiveness of the human brain and the body during sleep deprivation
periods so this is just fascinating i cannot wait to find out how this goes but i'm going to be teaching for like
more than half of it which is really frustrating but i'm really hoping every week yeah exactly scott this is scott's
normal oh you'll have to come on at the very
end of the global star party if he comes on exactly so the other thing that's happening is solar sphere now solar
sphere happens on the last day of alpine so i was hesitant about whether to share it or not except
that solar sphere is on uk time so the first music show happens at 6 a.m eastern daylight time and the whole
program goes through the day i'm actually talking right before alcan starts for us here in uh on in north
america so if you're interested go to solarsphere.events it's a fun and really
just engaging show combining astronomy and music and what i really want to talk to you
about today is the moon and how we can capture the moon and we're really lucky right now at this point in time because
we have the satellite the lunar reconnaissance orbiter that is constantly orbiting the moon and giving
us these beautiful clear pictures of the entire surface of the moon we get to see
everything in incredible detail and that's fantastic for knowledge and for understanding what the
moon looks like but let's face it for us here on earth that's not what we see what we see is the phases of the moon as
it moves through the lunar month we see from the waxing crescent to the
first quarter waxing gibbous full moon waning gibbous third quarter or last
quarter waning crescent and then the new moon and the new moon of course we can't really see it unless there's an eclipse
in which case yeah we get to see really fun stuff so when we go out and we try to look at
the moon we're trying to capture the part of the moon that we can see now i've sent my students out to do this and
i even shared this i believe in mid-may at one of our global star parties where i have them go out and try to sketch a
few objects and identify what they are from two phases of the moon i want to
make sure that they can at least identify when the phases are changing and it really is an amazing
activity for them to just get them out under this night sky looking up at an object that's been with
us for our entire human history and well before that but for our entire
human history the moon has impacted pop culture it's impacted religion has impacted all aspects of our life
right i do become a werewolf every full moon i i've been told it by my family i go completely nuts and of course very
very hairy that part doesn't seem to go away though so when i get the students out and i get
them sketching the entire moon it's one type of sketching it's really either
naked eye binocular small telescope or even your dslr camera but it's trying to
capture everything all at once there's a different side to it when you actually move this
into outreach so one thing i do in outreach sometimes they'll put up the current phase of the moon and i'll
invite people i'll give them a little box with a bunch of golf pencils and index cards and i'll invite them to draw
what they see at the 2018 general assembly in ottawa i
believe it was or 2017 or 2018 they actually set up with a picture of the
moon a large sheet of paper and a camera and invited people throughout the day to sketch part of that moon and then they
had a time lapse of the moon taking shape with multiple artists multiple authors and that was just amazing to see
what we do in outreach when it comes to a full moon is we actually go to the moon and the moonlits and we look at all
the moons of the solar system and we give them posters to inspire them to try to create their own moon or their own
planet even and so we give them a set of supplies we give them styrofoam balls we give them markers we give them pipe
cleaners we give them anything that can really just draw in their creativity and especially for youth
we just let them go wild and they will make the moon that they think that they will see around the planet whether it's
one in our solar system or a moonlet that we haven't quite discovered yet one that already exists or something that
might be around an exo star a stellar system somewhere out there in space and
an exoplanet with its exomoons so we really encourage their creativity
with the build and moon project but once we were starting to do that and we saw that a lot of people were really
entranced by the craters and the seas of our own moon
so we decided to start working on a project with one of our local artists who's a former president of ours the
china forge some of you may recognize the name because she's actually the program director for artist in residence
at seti and what bettina does is she does crater sketching with a purpose
she did what's called women with impact she's she sketched every single crater named after a woman and there's only 30
of them out of the thousand plus craters that have been identified and named on the moon in order to bring light to the to
the point that the women are not represented on the moon and in this another thing
that came out is a lot of the original uh astronomers in both the greek times
and the roman times are recognized but a lot of the muslim ones aren't so we worked with the agakon
museum in toronto to take the lunar reconnaissance orbiter pictures of the
craters that are identified with muslim scientist names and let people sketch them and learn a
little bit about those specific scientists so the way we did this is bettina did a
training session for my students and a few of our rasc volunteers where she walked us through a process for crater
sketching we then set up a booth outside of the agakon museum at the cosmodome in
montreal at the planetarium in montreal and we encourage people to try their best to draw the moon and to capture as
many details of a crater that they found of interest that they could i'm going to walk you through this
process a little bit what i call crater sketching 101 and the very first thing you need to do is have pencils
now you can just do this with one ordinary pencil and just change the amount of
push that you put on the pencil change how sharp you make the pencil but it's better to do it with artist pencils
where you have different levels of softness and hardness to the lead and you can change not just the way in which
you draw it in terms of shading versus actually drawing in lines
but you can also use erasers or your finger or a q-tip to then blend in the
colors once you've played with the grays an optional
step is to actually frame your targets when you have an entire crater
sorry let me just turn off my background here you can see this
when you have a full crater there are a lot of ridges and a lot of dynamite valleys and mountains around that crater
due to that impact not being on its own and sometimes due to that impact being incredibly forceful so what often helps
is to take a small circle and actually frame just a small part of that crater the part that
you find of interest that you wish to sketch so framing the target allows you to
focus a little bit more and the other thing you can do as you can see here on this target is you can actually put little
artist pointers and those pointers allow you to cut up your picture yourself into
quadrants once you've done this your next step is to outline the larger areas so not just
the shades the risen areas the additional craters inside of a larger
crater but even any area that you find of interest simply outline it outline it
lightly in case you decide that you want to change it or you decide that you need to erase part of it
but then the shadows get filled in and here's where our moon gives us a little bit of a bonus because if you're using the
pictures from the lro most of them are head-on which makes it very difficult to get any shadows but if
you get ones with shadows because there's no atmosphere on the moon those shadows are completely black so you can
take your darkest color gray and just fill it in completely and that now gives you a reference area
for the rest of your drawing now you color in the grays and you start with the darker ones then you go lighter
or you start with lighter and go to darker depending on what pops for you personally i make lots of mistakes so i
always start with the lightest ones because if they turn out they need to be darker then i can just darken those
areas uh it's a little bit harder to just go erasing again and again and again
finally you draw in the details when you draw in the details the crater's shape
really starts to pop archimedes is one of my favorite targets as you could see behind me earlier with
my uh virtual background that i had what i really love about archimedes is the
crater with the shadow speaks to different people different ways and so i've got
for you two different pictures here drawn during the same event from the same original picture
one of which really captures the coloring and the other really captures the height of the crater walls
and it's a simple difference in terms of what popped from that picture for that
particular student our zach one of the ones that we used at
the agakon museum and at other places this is one that people really seem to love to draw because there's so many
intricate features inside the crater as well as around the crater this is one
that's used with the targeting circle and they tried to remove most of their targeting marks from around it so that
they had a final product that they could actually walk away with now one of our center members nicole
laporte who's remembers liaison she does this sort of thing right at the telescope now observational astronomers people who
look at the moon with binoculars you know that that terminator line moves really fast when you're looking at the
shadows on the craters those change incredibly quickly so she has a setup
with a small set of cards that she uses directly at her small refractor and she's able to capture some of these
craters incredibly quickly and what she does is kind of the same thing what patina was suggesting is she grabs the
larger parts of the actual features and then colors and shades in later once
she has those larger parts that way even if the terminator moves she's already
sketched out the size of those features one of my friends in astroradio rachel
wood she does pastels on black art paper and oh my word do those pastels pop
and she has yet to frame these but i really think she should because these are just breathtaking
now speaking of breathtaking mary mcintyre who was our speaker on july 31st for our rask montreal center
event she does pastels but she also does time
lapses of her entire process so if you're interested in learning more about
how to do crater sketching i find her to be one of the best references that i have so i put her website here for you
mary mcintyreastronomy.co.uk she does not just
craters but she does everything that she does observationally or that she captures in astrophotography she also
sketches and just recently she finished a 60-day sketching challenge a different sketch every day for 60 days and she
captured all of that in a youtube video so you can also visit her youtube channel
now if you decide that you want to do a little bit of this crater sketching yourself for outreach there's a few
different things you can do i went to the lro website as well as to a couple of textbooks that i work with
and i took really good resolution images of many different craters and i just had them
laminated so that i can put them on the table along with sets
of these artists pencils and a whole stack of paper so that they can go ahead
and sketch their craters as they wish we also often put lots of these little targeting circles that we even just cut
out as people are sitting there but the other thing that i really suggest and i talked to david eicher
about this earlier is astronomy magazine put out moon flash cards for the moon flash cards you have
32 craters ridges or seeds and all of these cards have on the back
all of the information about the crater that that individual is sketching so now
you're not just allowing them to express themselves artistically and to see some of these features they're learning about
the craters that they found interesting and so these you take them and you put them in those protective photo sheets or
in actually sports card sheets that you can get at hobby shops and that way they're
protected and you can use them again and again and again this is a fantastic outreach activity
scott that's all i wanted to share tonight i hope that was enjoyable and i hope people got some ideas on what you want to do yourself at the telescope or
as an outreach activity at your club i think people are getting out pencils right now
so one thing i want to say sorry um i don't draw
i have never been confident in my drawing ability i go out of my way not
to draw i did as a kid in school i did all my life i sat down to try to draw a crater and i
was amazed with how much detail i could capture i cannot stress this enough it doesn't
matter what your drawing ability is you can work your way forward if you find this of interest but just trying to
draw some of these details teaches you about these craters it teaches you about this process that has
transformed our earth our moon the entire solar system and so really
no matter what your skill level is no matter what your confidence level is in your drawing
take a pencil in hand play with some grays start looking at one thing that you find
of interest and start trying to sketch it out and you'll you'll surprise yourself i guarantee you
yeah and if you're doing it at the eyepiece it makes you a better observer too because you notice things tiny
details that um at you know first glance even a long glance uh
you'll miss but as you start to assemble your drawing as you're looking more and
more you'll start to see greater and greater detail and this not only works for things like
craters but nebula galaxies that kind of thing you'll be really blown away by how
much you actually see that's exactly it i couldn't draw and nebulae i couldn't get my head around it and then i saw
that nicole does it on black paper with colored pencils and it just makes sense i can't believe i hadn't thought of it
myself earlier that's great that's great kareem uh uh i
promised that i would write down that bitly link can you go show that to us one more time sure um that's for the townsend
yeah yeah one sec
sorry about that nope there we go
okay so https bit.ly
townsend 2021 and honestly i i've had a few
opportunities now to chat with elizabeth uh in person or on phone as well as by email and
her communication i mean she is i i'm incredibly impressed and so she's one of
the writers for our sky news magazine and she's been doing a bunch of public talks she's also an author she's written
books with both david williams the astronaut as well as a book for the
search for life on mars that she co-wrote and then her own books that she's written on the possibility of time
travel and it's just it's amazing work wonderful wonderful
yeah definitely something you guys will want to sign up for um and uh if i can make it i'll be there
too so fantastic thank you thank you kareem thank you so much we are going to take a 10 minute break now um so it's
time to stretch your legs maybe get a coffee grab a sandwich whatever and we'll be right back after 10.
this is scott's 10 minute power nap so that it's not 140 hours straight
that's right right i put myself into a short coma you know
that's right that was a a great great presentation on kareem
congratulations thank you nicholas yeah excellent work kareem so the bar is
set extremely high in rask so i've got a whole lot of work
ahead of me but i embrace it because i'm here now so i showed a couple of your pictures to
some of my rask friends the other night when you sent them to me and their jaws dropped they're loving your work
well i appreciate that if any of them end up on sky news it will be a severe
honor but you have to submit to their photograph of the week i mean i even got my solar
my solography one on there so they'll definitely i mean yours puts mine to shame
i gotta look that so i just have to look up that website then and figure that out because i'll send you the link i'll send
you the link and i'll yeah i'll be happy to submit a few images um
what am i saying steve will send you the link he's a he's a rask center president i'm just a lowly public events
coordinator yeah either
that doesn't sound as modest as you think it does pleasure meeting you steve hello adrian
how are you where uh where are you located i am located um near detroit michigan
we'll we'll go there i'm in i'm in um uh southwest half of michigan i keep
wanting to put my hand up and show you where i don't know yep so near
not far from sarnia i'm kinda i could have joined the windsor um
the windsor group or the windsor center probably is easily maybe even a little
shorter distance but i find myself going toward the direction of sarnia more than
i do um towards windsor so i decided to just join that and i've in
anticipation of being able to get there in person one day uh crossing the blue water bridge so
that's the uh that's the path that i usually take to go get my images i end up heading up north in the thumb where
the skies begin to get darker as uh near lake uh huron so
that's one of the typical places that i go um to image uh
after being on a couple of shows here um i was convinced i need to go ahead and
join the rask so kareem did a wonderful recruitment job and
voted uh david levy and now i'm in the rest fantastic well glad to have you
yeah and i i used to be i used to be president of the mississauga center um
uh i can't say i did anything glamorous other than help rewrite the bylaws so that that's about it but um
i i went in for a term did what i wanted to to do move things forward and then i stepped back just uh because of other
commitments that i'm involved in so yeah and we have a uh group great lakes
association of astronomy clubs and i'm a member of a few of the clubs i'm also the president of that
organization um it's interesting to see how you all did the
the astronomy night with people and using screens yeah
we came to the conclusion that we were just going to do live views like we like we do
through this stuff the star party here um there we wanted to have an in-person event but we don't have as many club
members that are as savvy with uh sharing their screens as opposed to the
eyepiece so the big interesting thing was was that we used the next y-zed for
three of the telescopes so three of the telescopes we just put our smartphone right on top of the eyepiece and that's
how we did it yeah yeah the simple solutions to
um yeah those sort of that that may have worked um
so yeah we we discussed it and we said well this is the safest way we could do it here in
michigan we were getting a resurgence of cases so yeah that yeah that concerned a few people so that
uh i mean at this point we did we did this past weekend with one city and very
controlled environment uh with a gate at the park and
controlled entrance everybody signed up we had a contact list all of that just in case anybody comes down with it
we can do contact tracing so i'm still sitting here with the list for another week and a half waiting just in case
yeah and that's that's kind of the limitation and so that's why we don't have another one scheduled at the moment
our hope is observe the moon night in october that we can do one more this year
and then if things work out well then december for the geminids we can do another one
yeah it sounds like um we did a lot of good present uh preparation for it so that's yeah that's
something that we we would have to do more preparation
and account for those like you've got the uh you have that uh gated entrance which
really helped we have to account for those of those that come along that struggle with the idea of the masking
um we we deal with it but i know that in the astronomy community um
safety is much you know safety is very important you know as as important as um just
getting out there and viewing the night sky so we're we're hoping things move along because
we do miss sharing the night sky with the general public part of the reason i do my imaging
is well here's what you can see if you go out in the night sky this is what it's like and um
it's kind of me observing it for the masses who
you know we can't observe in mass or we we don't want to observe in mass because
of the risks um i go out there and enjoy it it's
understandable risk it really is and what we've been doing with the global star parties and with live streams on
facebook and sharing images it really does fill the void to some degree
and one of the big things is is there's a lot we can do online that we can't do in person which really does benefit
people the difference unfortunately is that when you're not in
person the follow-up questions you can't always see the people who
don't have a voice but have the question you know what i mean when we're in person even covered with
masks looking at people's eyes you can see the little kid whose eye is popping
and he wants to say something but he doesn't have a voice yet because there's too many other people talking
and so i just i would send a student close to that person and their parent and say find out what that question is
and then they would answer the question and those are the things you can't do online especially for the youth because a lot
of the youth don't really like they're zoomed out from classes last year they're not
they're not attending as much no i i would agree
and um yeah so it has changed our the way that we share the night sky and share
astronomy topics with people but it also using archival data from now i think it also has made us better presenters
evidence of water vapor in the thin atmosphere of jupiter's moon ganymede
ganymede is the largest moon in our solar system larger than mercury and pluto and three-quarters the size of
mars it's an ice-covered world that may hold more water than all of earth's oceans
combined but unlike earth ganymede's oceans are below its 100 mile thick icy crust
ultraviolet images taken in 1998 and 2010 using hubble's space telescope
imaging spectrograph revealed bands of charged particles at ganymede similar to
earth's polar auroral ovals the regions that give us our northern and southern lights but the two observations revealed
differences in ganymede's auroral bands over time the researchers thought these differences were due to the presence of
atomic oxygen or single oxygen atoms in ganymede's atmosphere atomic oxygen
affects one of the wavelengths of ultraviolet light the scientists were looking at in 2018 researchers used hubble's cosmic
origin spectrograph to measure the amount of atomic oxygen in ganymede's atmosphere they compared the 1998 2010
and 2018 data to their surprise the 2018 data revealed hardly any atomic oxygen
in ganymede's atmosphere there had to be another explanation for the differences in the aurora images ganymede's surface
temperature varies widely throughout the day and around noon near its equator it may get warm enough for surface ice to
release water molecules instead of melting and forming liquid water the icy surface warms and changes
from a solid directly to a gas a process called sublimation
looking back at the original images the team discovered the differences they observed in ganymede's auroral bands are
related to where water vapor would be expected in the moon's atmosphere understanding the jovian system and
unraveling its history from its origins to the possible emergence of habitable environments will provide us with a
better understanding of how gas giant planets and their satellites form and evolve
along with learning more about jupiter and its mysterious moon ganymede this exciting new discovery has brought us
closer to understanding our own place in the universe
[Music]
well we're back um i i hope you uh had a a good 10-minute stretch there and uh we
are back i think that we were supposed to have jerry hubbell on but i don't see him and
so up next is john briggs uh john has um has a powerpoint presentation he'd like
to show and uh we're proud to have him back on global star party it's been a little while
how are things been john hi there just fine
and um i'm glad to be back and i have another uh historical
presentation and i i pre-recorded uh the thing and i'm sharing it from
the vulnerable internet of rural new mexico and um if it if it if it doesn't work um please
button and let me know and i'm not that experienced with uh screen sharing when
you when you share it john on the left-hand corner it says uh share
computer sound or something like that it's a little check box yeah you want to check that yes it says
optimize screen sharing for video clip what about that um yeah why not
okay
and uh
i don't see i think i'd go back and
un-share and then um you know click on the powerpoint
um application itself you'll see when you do it
we all had to go through this yeah sorry sorry folks no it's cool
yeah uh unshare your screen and then um
and then you can uh let's see
stop share okay there you go sorry about that all right now go back into the sharing feed button the green share
screen button and then before you commit you're going to see your
powerpoint application and you want to click on that and you'll
it'll draw a green box around it and you'll know that it's highlighted okay
sorry i'm moronic at this share screen
oh there we go yep wow
well now i guess i just go slide show yeah we're beginning
thank you for your patience no problem
hi everybody this is john briggs speaking for magdalena new mexico
and when i heard our theme this time was moons and moonlets i wondered what kind
of show-and-tell have i got at the astronomical lyseum that would relate somehow to moons and
moonlets well i thought of a few things
well we have a lot of books in the collection at the astronomical lyceum and when i think of
the history of moons in the solar system i always think of how barnard discovered
the fifth moon of jupiter the first one discovered after galileo
found the first four so it was quite a big deal when barter did that but barnard wasn't the only
american who discovered uh early satellites in the solar system
and we recently spoke about bardet in one of these presentations because
edward barnard is so famous for his uh photographic atlas of the milky way
we can review that very briefly here's the two volume atlas
and only about 800 or so copies of it were produced in the 1920s
after barnard's death but it was revolutionary at the time because
no one had seen wide-angle photography of the milky way the way barnard
started recording it back around the turn of the century so it made a big impression
here's the title page of this famous photographic alice
and here's what it's like inside this alice when you open it to a random place
beautiful black and white photography of the milky way wide angle photography
and many of the pictures record nebulosity as well
and many of the images recorded what came to be known as dark
nebulosity and these were particularly interesting and mysterious to astronomers
but that's of course another story we spoke a little bit about it before how did it come to pass
that barnard had the circumstances to create this famous star atlas well
part of it had to do with his history as an amateur astronomer
being wonderfully successful discovering comets with his own five-inch refractor
that led to barnard getting a job at lick observatory when it was very new
lick was dedicated in 1888 but within just a handful of years
at lick uh barnard discovered the following thing
he discovered amalthea in 1892. but he didn't see it like this it was
just the ever so faint object very very near jupiter inside closer to
jupiter than the galilean moons but he recognized it as a moon
but this was really uh [Music] well publicized uh news
back then and barnard became wonderfully famous
because of this discovery nobody discovered a moon around jupiter since galileo after all
and barnard uh relocated he got a new job at brand new yerkes observatory of
the university of chicago with a 40-inch refractor now the observing conditions were not so good
at yerkes observatory as they had been at the lick observatory in california
with a 36 inch refractor but barnard had good resources to do new
things at yerkes and that's what led to the photographic
star alice but amylthea wasn't the first moon
discovered by an american astronomer there were others like phobos who was
discovered by asaph hall at the united states naval observatory
with a 26-inch refractor in 1887 august of 1887
as well as another one halt also discovered deimos phobos and
deimos the the moons of mars meaning fear and terror
the companions of mars is the god of war
and even long before that in 1848 hyperion was discovered as a moon of
saturn by william and george bond at harvard
college observatory with the brand new 15-inch refractor imported from germany
uh that was referred to as the great refractor there were
really none larger in the world at that time when the 15-inch was dedicated in 1847.
here's what the 15-inch at harvard college observatory looks like today
is very much uh as it was when the father and son team of the
bonds used it for hyperion
here's what the 26 inch looked like when hall used it for the discovery of
phobos and demos telescope is still in use at washington dc
you doing speckle interferometry of close double stars
but it's been remounted so it doesn't really look quite like this anymore
and here of course is what the mighty lick 36-inch refractor
looked like when it was new and it hasn't changed much since its dedication in 1888
this is what barnard was so happy to finally get his hands on
uh as as one of the junior astronomers at lake and whereupon in on very short order he
made the monumental discovery of jupiter's fifth satellite
now i think you could make history of astronomy especially interesting if you can
personally connect with it somehow for example with the discovery of the
moons in the solar system we can aspire to see them ourselves
um it's a challenge to see most of these little moons but certainly possible with
the equipment we have access to nowadays another thing you can do is you have
access to an interesting astronomical library is look up some of the early
publications that related to these discoveries it's simply
neat to be able to do that
when squirrel observatory of swarthmore college in pennsylvania shut down a handful of years back
um the college very generously gave me
most all of the observatory's astronomical library because i simply
had a place to put it and preserve it and among those things
included a really wonderful run of us naval observatory publications
now i had seen a paper among those publications
when i when i shelved this stuff a few years ago relating to the discovery of
phobos and deimos by all so i thought why don't i just get that out and share
it with folks because it's pretty neat i had some trouble finding it oh there are many many volumes in the
run they look something like this
okay so i opened some up uh trying to find it and i found this
orbits of phobos and deimos but wait this isn't right these are from
observations in 1907 way after the discovery by by hall
i had trouble finding this paper i remembered seeing the discovery paper by
hall i thought it would be fun to share that with you
well since we just happen to have this paper open it's kind of interesting to see what these early united states naval
observatory publications are like they're printed with fairly big text
they're easy to read they can be interesting things are better getting explained here
the astronomers talking about how he used the file or micrometer eyepiece to make the measurements and all that it's
interesting by the second page of this paper though
uh the text is getting pretty darn mathematical that's interesting too
um but it's it's that's not what we're looking for
so i had a little trouble finding what i was looking for but fortunately i had this
basically an index list of publications issued by us naval observatory 1845 to
1908 and i looked in there i was directed to this
thick tome
astronomical and meteorological observations made during the year 1877.
and buried in there in a section observations made with the 26 inch
equatorial 1877. by the way look at the top of the page
and look how they're using roman numerals for the aperture of the telescope you really review your roman
numerals using an old book like this there's a table results of observations
for the satellites of mars and there's a table for phobos
the first observation being in august 17th and down at the bottom there's the
beginning of a table to continue to the second page for deimos august 11th it
starts the thing is there had never been before
observations like this with measuring the position of phobos
and deimos but i knew there was a publication with a little bit more fanfare related to the
discovery than just these tables
it took me some trouble to find it but i did find it it's actually an unbound
paper but interestingly it's autographed by daniel kirkwood
september 23rd 1878 kirkwood is for whom university of
illinois named their observatory and if you study the distribution of asteroids
in the solar system you'll hear something about the kirkwood gap
having to do with the lack of asteroids in the main belt because of gravitational effects
kirkwood was a was a a well-known astronomer specialist in celestial mechanics but anyway what's the paper
observations and orbits of the satellites of mars with data for ephemerides in 1879 by
asif hall this is it this is really the the more
lengthy scientific publication celebrating the discovery
of the moons of mars so the satellites of mars it reads and
it begins in the spring of 1877 the approaching favorable opposition of the planet mars attracted my intention and
the idea occurred to me of making a careful search with our large clark
refractor for a satellite of this planet and of course the narrative goes on and
if this is still a relatively formal account
of what hall did it's not exactly what maybe mainstream
media would do today celebrating a discovery like this but it was big news and of course it was
reported in uh newspapers of the time and all that but in terms of astronomers reporting it
to one another well this is a classic from united states naval observatory and it's a lot
of fun reading through something like this
so i found what i'd remembered shelving a few years ago about the discovery of the moons of mars
but turns out also from swarthmore our library here got a huge collection
of publications of lick observatory volume 1 volume 2 volume 3. it goes on and on
as barnard made his discovery in 1892 i thought it would be discussed
in these early volumes but it wasn't i'm going to have to dig deeper to see
how lick and barnard formally publish the discovery it was certainly world news at the time
i also tried looking through barnard's published papers but even among those looking today i
have not found his discovery publication
but while i was looking for a discovery paper by barnard
i looked up at a lot of other of his papers let's just glance at the titles of things that barnard was
publishing around that time observations of the planet jupiter into satellites during 1890 with the 12-inch
equatorial of the lake observatory note on the first satellite of jupiter on the phenomena of transits of the
first satellite of jupiter micrometrical uh measures of the ball
and ring system in the planet saturn are measures of the diameter of a satellite titan
now wait a second thinking about that i mean when it's it's kind of a thrill just to see titan through a telescope
nowadays right generally it just looks like a star but when you're using the 36 inch refractor
at lake observatory you see titan as a disc and the diameter of that disc is
measurable further barnard did things like the second paper file or micrometer measures
of the diameters of the four bright satellites of jupiter made with a 36 inch equatorial
it's quite an impressive thing when you think about it measuring the diameter
of the disks of the jovian moons and of saturn's largest moon
but if that were not enough look at what else barnard did in those
days he essentially successfully measured the
diameters of asteroids which most of us have only ever perceived as nothing more
than stars that's why we call them asteroids star-like
but he measured the diameter of ceres palace and vesta
visually in this case with the 40 inch refractor at yerkes
how did barnard do things like measure the diameter
of jovian satellites and titan and even asteroids
well it was a with a filer micrometer eyepiece a very elaborate moving
crosshair eyepiece with a finely graduated scale for distance and position angle
this example was made by the alvin clark and sons family
just well the same company that made the one that uh barnard often used
just a few more things i'd like to show you before we wrap this up barnard also studied the surface
features on the satellites of jupiter like this paper describes on the forms
of the disks of the satellites of jupiter as seen with a 36 inch equatorial of lick observatory
the sort of thing he was talking about was how a moon of jupiter because of its surface
features would appear to change shape as it passed in front of jupiter
and the contrast effects and various issues you'd have
would make for a very confusing picture he understood what was going on
but he was illustrating the appearance for the sake of uh just explaining the
phenomenon here's an illustration from another one
of his papers when i first saw this years ago it was the illustration down in the lower right that really blew my
mind um it's showing a superimposed on a band of jupiter
um a moon that has a light equatorial band it's a
small disc within the drawing in one case the disc is superimposed on a light
jovian band on the lower in the lower case the uh the moon is superimposed on a
dark disk so in one case it looks like there's two spots
in the other case it looks like there's um a bright line
so this is uh the way uh the moons of jupiter can appear to change as they
pass in front of jupiter barnard was familiar with these things so he
recorded these things and he's laying down a challenge for us with good optics and good seeing to
repeat some of these remarkable observations when we have a chance
today and of course in barnard's papers there are occasional illustrations like
this showing uh how he could see saturn with the 36-inch refractor that lick
observatory anyway my point in this presentation is to simply remind folks
the historical literature is out there and it's really fun to explore it
unfortunately many libraries research libraries are literally throwing
publications like these away i have these publications because they
were given to me because people were throwing them away
obviously for most of us they're way too cool to allow that to
happen hey thanks thanks for your attention tonight take care
that was great john yeah and and the presentation came off
uh uh excellent and the sound was awesome so yay hallelujah i guess i
i just can't take that for granted and uh but i'm uh with your guidance i think
i'm getting better at uh screen sharing here and all that there's one error um at least one
small error because i put i threw this together today um
but i said the kirkwood observatory is at university of illinois
and that is a misstatement that is a lie the kirkwood observatory is at
university of indiana uh just for the record uh
but uh when i try to hold these little presentations together uh somewhat spontaneously
i find i occasionally misspeak and uh that was an example but no big deal but
uh but thank you for the opportunity uh for letting me share thank you thanks for coming back on the
global star party you bet awesome good night all right well up next is uh deepti
gutom a young astronomer from nepal uh she has given many presentations on
global star party and uh we're proud to have her back tonight um what time is it in nepal at
this point 15. it's 8 24 a.m okay all right
so quite a time change from arkansas where it's uh 9 49 here so
in the in the night of course um well that's wonderful uh uh
you have given uh dt has given great presentations on a wide range of
subjects in astronomy but she's also done uh some beautiful poetry for us and
so i i don't know what she has in store for us tonight but she assured me that it would
be uh in line with the theme of moon and moon moons and moonlits
uh tonight so dt i'm going to turn it over to you
thank you and hello everyone and today i'm on talking about uh is in
team about the moon in moonless and as we know the moon is our national
satellite and the moon is uh very slightly uh uh skeleton and absurd due to the tidal
stressing with its long axis and displace 30 degree from facing the earth and due to the
gravitational uh force from the impact basin or its itself is more elongated
than current tidal force uh you can account and yes you know it is the largest natural
satellite in uh comparable to the uh it is the largest mississippi slides
so let's turn related to the size of its planets and uh the fifth largest light
in the solar system overall it is larger than any non-dark planet orbiting earth
at an average distance of uh 3 300
800 800 800 40 000 and 400 kilometers or about 30 times all diameters and its
gravitational influence slightly lengthens earth's day is the main driver of the earth dies and the moon is
classified as a planetary mass offset in different state rocky body and lacks any
significant atmosphere or hydrosphere or magnetic field and its surface gravity is about one-sixth of earth and jupiter
moon is the only satellite in the solar system known to have higher surface gravity and
density and there's four hypotheses of the formation of the moon that is fission theory and
fusion theory is for this that at one point the earth was spinning so fast that uh part of the spawn of from the
moon and uh another theory is capsule theory and another is go estimation theory and
uh giant impact they have this this enzyme impacts hypothesis is most accepted uh theory from these all
and uh but there's a question why is a highly accepted theory uh giant impact
theory but uh if so you know then if the theories uh formed um
prove that uh it's proposed that the moon formed during the collision between the earth and other planets uh obviously
the size of mars and the babies from this impact collected in in orbit around us to form the moon and
talking about the moonlight and moonlight is a minor moon or minor nests of satellites
or minor satellite is a particular small neutral satellite orbiting a planet dark
planet or the minor planet and uh this uh once they uh is there any
moments of the moon too but uh here is the three different type small moon that have been called
moonless after now there is a belt of object uh embedded in a planetary ring
especially around the saturn and such as those is a a ring or yes 2009 years into in the
bearing there is proper propeller moonlights and those in the earth rings and
occasionally asteroid moon such as the sorts is of those of uh 87 salvia and
flash is in near jupiter moon and that is called amalthea that is
likely debris ejected from its surface and some satellites are also called
moonless and i have
okay
i have been involving outreach programs by taking out this
telescope and i'm planning to try the
rocketry that is i am i'm making sugar rocket
by by the help of powdered powdered sugars and potassium nitrate and m seal are 50 liters
are you making your own rocket engines are you making your the your
did she freeze up here
hello hello you're back
yeah yeah and i'm making a kind of model rockets
but it will fly uh up to the minimum height or not in the maximum largest
height but um i want to uh
i want to make slightly
related to it and it's important in the sector so i'm planning this all and
today i'm planning to
[Music] i'm planning uh to make and uh today i
have got one point by anything ethical that is a man in the moon okay
come hell or rain or slate or snow outside is the place i will always go to
look above the sky at night to tell the moon in maine my flight my eldest side
will always know the promise i made a long time ago but i felt if i'm near or
far away the moon is the moon will always come to me my love for you will never fail and every time you cleanse
his way never remember dad send his love your way and
similarly there is i will bring you the moon and um
as you all know the in the scenario of love or anything is
the people's promise to take this moon or anything okay uh so this story is uh
this poem is ready to death i'll bring you the moon take it and you catch the sun could you
i will i still actually tell you the truth painful to remember the night will you dressing off and so kind fizzing
he's kissing me and so strong holding i'm a bit sad listen all had happened so
fast wildly i could not understand funny thank you [Laughter]
thank you very much deep teeth very nice yeah uh
so when you make those rockets be careful okay it's it's uh you know they can uh
you know they can go boom be very careful but that's great the program so you're running out there
i'm bringing the guidelines of one brother uh he is doing rocketry
right now and i am taking his guideline yes okay
all right excellent well up next is uh maxi folaris and
maxie is now becoming a regular on the global star party uh he's down from
argentina not not such a short distance away from cesar brollo but
they've become friends they've known each other for a while um and uh
it's great to have uh maxie on on the global star party
well scott hi everyone well it's good to be back in the gsp
and well last weekend i was a
a little sad because the the thursday is our night
so uh i i didn't know what to do that night so basically i think really
yeah so well tonight the subject is about the
moon and moonless and what i want what i wanna talk
tonight is uh some pictures that i took uh a couple of years uh and shortly time
from now and let me show you my screen uh to
[Music] i want to share some perspective that i saw today
uh i went to my backyard and wait let me wait a second ah here
uh well i think it's okay do you see stellarium yes
okay this is the uh this knight
this is from my sky this is arturo arturo venus spika
in virgo constellation and this right here is the iss
okay so um i i knew that
this la this night is what it would it would be very brighting
so i remember that now so the time and
went outside and i see how
it starts to move but when i
realized uh it was passing by very short of the
of the moon it was very above my head here santa is
scorpius and like we talked with
pika hotel every time we
want to to take a five-minute break to watch the sky
and this is a a very good perspective of
an international space station our satellite
a natural satellite of course and also jupiter and saturn
and behind of all of that i can see scorpius this was a very
deep a kind of of see the sky this is something maybe to to get
simulated and of course the iess was passing by and
yesterday i didn't know that the s the iss
passed through the moon from my location and i missed it you know
i saw the iss passing um coming up then
it started to to get a very less shining and disappear
i tried to to take some pictures but i didn't realize that
it was passing up in front of the moon so
i i missed somebody made a great picture right yeah i i think i think
yesterday it was a very windy night a very this weather
in this week is very very rude
so there will be another next time i think
fortunately the iss passed almost one hour around the world
so well this is a little simulation of what i saw tonight and i was and i
thought it was very good to share with all of you so
like i say tonight we're going to talk about some pictures on the moon that i took
a couple of times ago i think it was in september last year this it was with my qhy
and the f5 telescope that i don't have anymore he go he went to some place in banfield
i think nico knows that but it's here
it keeps in the front friendly uh association
let's say so this is taken without a camera and a focal reducer a 0.5
and then this is a primary focus and then i put a parallel to x
and then a value 3x and the 2x this is uh
you can see he this is the region that i want to get soon
if you see in the next it's here and in the next is here
and then it's here uh this is also it was with a qhy uh i
don't know if that knight was very the jet stream it doesn't
er was good i don't remember this is another picture
in some holidays almost two years ago in this is the the
atlantic ocean uh in the place of santa clara del mar or
santa clara or saint-claire of the sea let's say in english
this is a small city behind a marble plata and of course in the uh
looking at the east i know the the moon is one it will come to rising but you
can see there was a thin cloud that i didn't see it and then i started to see this
very orange bubble coming up and and a few
minutes later it came this and then it came this wow
beautiful um this is a a
nature picture that i want to take the in the in the same place this was the
two days before um no two days yes before and yes
um this is a a birth of the place it's like uh
yeah yes and of course here's the the moon very blurred but
uh i i really i remember in this when i took this picture i i get to the ground like a
military and start to shoot to the birds
he was in the in a tourist place uh behind the sea and people
passing by through and this is a crazy man what he's doing and i don't care let's take pictures
um okay another picture of course of the moon
and also the sun this was the the last sun eclipse
this is the part that we see with when the passing through of course
of the in front of the sun uh between us and
of course it can show us the flours and the corona
and it's a it's a new unique uh moment
i i think in every time in every gsp i i share this kind of pictures because
i encourage everyone that has the possibility to see this
and every time they of course it doesn't happen
too often but if you can see it
please go to see it it's a a unique
life moment and a a very
inspirational smallness moment
that
did we lose maxie
maybe let's give him a couple of extra seconds
here see if he can come back
well i think that um i think that we will have to wait for maxie to come back
um and uh there we go
okay all right well uh overall maxie always gives a great presentation some fantastic
astrophotography and um uh sometimes uh the internet doesn't always cooperate
so max are you back i think i'm back you're back okay i'm back okay
now i i think my father's ec netflix or maybe some
fights downloading yes and streaming is killing me but
um well let me share the screen again okay because i i started uh
sure okay did you see the the eclipse uh i don't i don't we didn't see the eclipse
yes okay uh i say some words of inspiration but i think it's
yeah no no we we heard that uh this was something that everybody should see and and uh you were encouraging everybody to
go see you know a total eclipse of the sun which i couldn't agree more you know
it's fantastic in a moment that you can explain
it's it's a a moment that you have to feel it and oh and it will be on the years moment
and in i don't know it's a one like a one
a lifetime but if you can see another ones
it helps you to to know who you are where you are
and what's around you and and surround us uh well continuing to the moon this is a
try to to take pictures of three-dimensional moon uh
overexposition and taking single pictures uh in very short time and
with a few kind of second to to get the
the the the dark parts of the moon and see
the the all the structure and
well continue of you of course of the moons uh in our solar system and
we have some planets that have a lots of moons of course jupiter is one of us
and also saturn uranus neptune mars
and well pluto it doesn't anymore a planet but
has a a carrion i think is in english
and well this is a picture of
jupiter that is very often that of course of the size
of the planet uh that's the the moons uh that has the galileans moons uh io
callisto and europa uh passing
in front of the the the surface of the of the planet and
in that situation it it calls a transit of the moon and
eo for example orbits uh almost uh two days around the planet uh our moon
trans transit almost a 28 days in this case a eo
is very it has an orbit very fast but in ganymedes i think it is the most
um [Music] well i don't say i don't know the word
um it is low the orbit has the slope orbit okay um well
here's another picture of the moon eclipsing of course the surface of the
of the planet and here's a really short animation
oh that's good i think this was almost one hour you can see this is i remember this was
europa a rope and the and the shadow that projects
above the surface and here it will comes the the great red spots but i couldn't
take it here's another picture i think it was
the the no the another knight that wrote the europa
passing through because the great red spot this was in 2020s
and here's a single perspective of ours a natural satellite the moon
but a very [Music] a rare situation that
occurs when the moon pass in front of a planet and maybe is
um sometimes it's an occultation of that planet and sometimes it's a approach
it will get very very close and this is like a
panoramic picture of course uh taking off the of the border of the moon
and very short distance is it looks like a
is a mars a horizon of the horizon of the moon it's some
kind of a perspective that is
not a sun it's not a moon is a planet behind of course the
our moon uh well this is my little presentation
talking about the moons of course our natural moon i unfortunately don't have a any
uh pictures of saturn's moon a titan and
and another encelado or on another one but
i hope in the future could uh take some pictures uh well this is i want to show you very
shortly everything work of what i did last days this is was jupiter
last night i almost finished the the stacking and some kind of
trying to to get more more detail maybe two hours ago
this is a release from the the cooking process
uh the night yesterday was very
bad the the the transparency was fine but the chest stream makes the
the surface and the borders like a bacterium
moving or a frying egg that we say here and
last weekend uh i i was fighting again and nicole knows that
with the collimation of my scope and i think i finally could figure out
finally and this is some pictures to lego nebula
uh this it was almost one hour one and a half hour
taking pictures of about three minutes uh at it's so a 500
very try i don't i want to try to
take some dark pictures because uh with my scope the the the core of the nebula it
got um [Music] very shiny and it goes very white and
and that and this kind of nebulae the the in the core it doesn't see it so
i try to to to get more more detail in the in that case
uh this is my my last work i hope
the the you know what it will come in a few weeks i think from china
okay so it's traveling right now i hope maybe in a couple days maybe i don't know
we'll come here i i i maybe
when i have it i will do if the sky allows me i would try to do some
live work uh in the most of the gsp and see
how it works so thank you everyone i
show you again with scott and thank you all the audience i don't know if anyone has a
question or something or you can only find me on facebook and facebook
maxi falieres like this and and also in instagram
so thank you everyone thank you so much man thank you
really inspiring image there of the lagoon well up next is uh cesar brolo cesar is
uh also from argentina and uh has been one of the very first
participants on the global star party and still regularly attends
so cesar how are you doing tonight how are you good i am i am in the balcony again
yes was a mistake because uh the winter is here yet
um i yes i i felt too too too much confidence with this and
it's really a horrible horrible uh night with missed form if it's
possible all together windy um feel very the chilling the chill wheel
is really low but well i have the move in in a life it's incredible but i have something
to show you okay it's more it's more interesting to see my face see the moon
and of course that let me move yeah it's so so um
how the clouds are passing all the time and this is a fog that coming from the
river rio de la plata i say
yes the bride is so different that
really you can see how the the game is is putting out because it's
all time is is changing but but it's interesting because as it
fluctuates you see different details yeah absolutely absolutely well i i
showed the moon in a live in a live uh
how do you say in a live view to enjoy
of the entire group and the people that is watching the the
gsp tonight and [Music] uh i'm moving the mount the exodus 100
mod with this the table
and uh for centering the moon and uh [Music]
yeah i i had to that's not it this night i had
connected uh with the computer in serial mode my my
mount but i in a moment one hour ago i
put with the feet the connections and into off my computer and
okay i i reconnect all the game but with uh you know in
with the wi-fi mode with the i'm starting to use uh
with the my android
table and this is very easy to use no problems and like it's a night that where only
you can see the in the sky the moon not another thing you can see maybe the foggy
how it is moving all the time come out it's impossible yes i i'm
talking i'm changing all the time the exposure i use in a swbo
camera that entire camera and i can
you can see the the horrible scene because yes but you know it's a live image
yeah sometimes the seeing is so good and everything's just sure everybody is still image you don't know
you know absolutely absolutely when we i remember i spot that when we started the
gsp yeah we was lucky to show every every night
processing um moon and jupiter
unfortunately jupiter now maybe is a little impossible to
to to to make focus because you can see
the the problem that we have i have with the scene tonight this
is near to impossible it's okay for the moon you know because the moon have enough
enough pride to to to see and focusing in the sky
is the easiest and beautiful [Music]
beautiful publisher that we have the sky for for the people all the time i say that
for people that ask me what type of of
object i can see i can show i can i can show what by
by my telescope to my people that visit me in you know in a bbq
when you use your telescope in your garden back here so ever ever see the moon because then
other things they don't understand what are you uh show them
uh and of course the moon is is the solution for everyone because the people say wow
the moon if you watch nebula come on they say what maybe they they then they don't see
uh in the place where you can see the image and this is okay i i watch only
the same star that i watch in the sky okay yeah but the moon is
is inspiring is of course that saturn is incredible with the rings
but the moon ever ever if you if you have a people that
you're a guest is the best the best
thing to show by a telescope of course in this condition is horrible
but people say okay it's okay i think we like it anyways yes yes
it's a pleasure to return yes so i i i just i just shared the link
for weather where you're at in buenos aires and uh it's uh looks like it's about 55 degrees
uh fahrenheit and foggy so absolutely funny
is that the only thing that you can see in the sky now is maybe antares uh the moon
not another thing because it's and clouds that are moving in the sky from from the east
from the river it's something that maxi don't have problems maybe nicolas yes because
nicolas is more it's really near this in the south of the metropolitan area but it's near to
to this this place but yeah i'm suffering like you oh hi nicolas
it's the relation of argentinian
but here here i am only at maybe
no more that 700 meters from the the river under the size of this river is like a sea um
freshwater sea of course it's a river but
that have this when you have a east wind you have a problem and cold weather
you have a fog that is is really strong
but maybe what is maxi they actually have this problem
really really later or not yes it's different 200 300 kilometers
to the center going to the land it's another question but here is is
we are in the in the world pampa yeah you do have another problem with
the weather but uh i know that that here
when we have uh well you have a few days ago uh
3 p.m you have a lot of fog that i have a very
sunny day and you will have very like you don't see anything
everywhere at 3 p.m yeah yeah typically in buenos aires we have uh
at only no more than two or three kilometers we have an airport
and you know many many times the the planes are going to [Music]
going to arrive to cesar essays airport because here is impossible to see something
uh but you know it's the situation with this river is it's
normal that many times do you have a surprisingly enough in a
clear night turn fastly to the anointer like tonight
because i think scott that that i i was thinking and make a picture of m.a like the
picture that i showed you that i was thinking sure um that you watching facebook but i i
prefer that i would still present this picture and another ones next week
because come on the young people come on that's right
yes yes i prefer and well you can see you can see many times
it's it's going to disappear the moon um is break again because all time is
passing clouds and clouds but well okay it's it's something that is a light it's
a live image you know from buenos aires the moon
thank you very much thank you very much see sir well um
we have um of course more global star party here tonight and uh so we go from argentina
up to canada uh to steve malia from ontario telescope and
uh steve is also very active in the amateur astronomy
community he's been president of the royal astronomical society chapter uh in um
in toronto i believe right oh mississauga what's that in mississauga mississauga okay all
right just which is uh the next city to toronto just on the west side toronto
okay all right yep and um uh you know
the rasc is a great group too i mean they are very enthusiastic um they're
large they have thousands of members and the
group is involved in all aspects of educational outreach and astronomy so yeah
absolutely with the rac stretching from coast to coast all the way up to the north into the yukon where i had a
customer there complain because we sent out a an email of promos and stuff and he's he said i can't use
anything that you're selling because it's 24 hours of daylight right now
so i said how about a solar scope so uh
but uh yeah i know you're right like in all aspects of astronomy and outreach and education and you know just getting
together when we can safely um uh and observing and sharing common
interests and having um you know uh speakers and so on and
and scott like you were our our last guest last night that's seriously true
like in a in-person environment oh yeah that's right because i just come from
new york uh that trip to new york was the day that they had the first known covet case in
new york okay right and i i just left and uh was up in toronto and
visiting with you and uh and you were gracious enough to have me go to that meeting so that was great yeah it was uh
um i'm glad it worked out the way it way it did because it was um you gave a great uh presentation and i think you
had just did it that day seems like a common theme on tonight's program
um everyone doing a last-minute presentation and uh um uh actually i had some nice comments
afterwards that was nice to have that's nice it was a wonderful year and to have uh um
uh someone like yourself who has the longevity in the history in the industry uh come talk to us and
also have uh um uh you know just kind of it was nice to
kind of be acknowledged by by the industry as well right to have someone speak in there so it's really nice that
you're there but yeah you are you are one of these industry people yourself so you know it's uh yeah it's it's it's
you know you are i think that um you know uh
if uh more dealers uh uh invested into the amateur astronomical community like you do you
know caesar's also one of these people you know he's very involved with the amateur astronomy
community he's out there trying to uh rebuild this uh uh facility uh you know
this aging astronomical facility down there and and uh steve you you've been
involved up to your eyeballs in uh in all of this stuff and um
and you know i i know that uh your business has gone well and uh you know
so i applaud all that it's great oh thank you that yeah things are definitely going well uh things are busy
involved in a lot of things um i had to quit my job wonderful
so uh yeah this is um a lifetime commitment now uh we'll see
how it goes but uh no it it um it's a lot of funny we've done we've we've changed a few things here as
well how we're how we're approaching uh the market and getting information out and
you know where we're offering courses and and [Music] which i think is a form of outreach as
well right to help to share knowledge and knowledge transfer um i've launched uh ontario telescope tv um
uh ontariotelescope.tv which which is just me on a saturday morning rambling about
something um and uh it just takes you to a facebook page with with all my videos but um you know
it's something that we we're doing here it's just more ways of trying to get out there and and talk to as many people as
we can um to to share what knowledge we can share um and
hopefully it's absorbed and and uh and used in in some
ways well right of course you know it's by someone buying their first telescope um or learning how to
align it versus someone who's looking for something more advanced or into astrophotography of a new camera or they
want to automate their system or a piece of software or something like that but uh you know that kind of leads me to
what i wanted to discuss not necessarily moon related and and just so everybody
knows um you know i uh scott sent an email out i replied back right um and uh uh it was
basically uh do you want to join us so i don't really have anything to show except for a few pictures i took
recently it goes good you're in you're in boom here i am it's been a while i think the last time i was on was um
uh well when we did that marathon uh back in december right yeah you are
you are the official co-host of global star parties so right and that was a lot of fun but uh um so i've got a few
pictures and i want to show off you know i'll share my screen um
and uh why can't i share my screen
there we go all right i'm sharing my screen yes and this is a rig that i i really enjoy enjoy using um
it's my explore scientific is 100 with pmc8 and i like to say this is the very
first one out there because i pushed and push and push and push it yeah you got them you got our first um g11 okay i
believe and and and now this one so no yeah no this one and i i absolutely love it this is a
great portable rig has a lot of capability um i don't use the scope on it anymore i i
have a couple of other arrangements with it but i'll show something i did with this but it's such a great little powerful rig because we can i can do a
lot with it i i love doing wide field astrophotography um
and uh um let's see if i can do this better there we go
i love doing wide field astrophotography and i'll show the shots i've been taking with with this um
it's not really working for me the way i hoped um with this uh with this um
with this rig overall and and one of them you know one of the first uh shots that i took
was was this this is the uh the elephant truck uh nebula and i took
this over a year ago nice not working out sorry let's keep it like this
like that there we go um gotta love live right yeah um this is a shot i took over a year ago
actually this was at the uh location where they would hold starfest normally uh unfortunately starfest didn't run
last year it didn't run this year because of uh um regulations that we have to follow
right now and so on but uh i really enjoy taking this this is what was with a um actually with
just a dslr lens and um a nikon uh d810a so i was able to get a
lot more of that nebulosity um and then i i i you know went on and this actually took
last week again with the uh the similar setup um i used a different telescope
for it but again same camera and again on the uh is 100 and what i love about it is
you know simple to put to align it because it's wide field your polar alignment doesn't have to be
perfect perfect this has to be really good and um you know i pointed this up to uh
north american nebula and i got this great shot beautiful uh north american nebula with with a
pelican and a few other treats in there as well um but i was quite happy with this um i can't
actually take all the credit for it my youngest son jaden uh who's 12 uh really wanted to try some imaging so uh we set
him up with this and i i taught him how to use the zwo um
which controlled the mount flawlessly and uh my camera as well and uh uh we
got this great great image and and really you know for anyone's looking to get into astrophotography
um wide field's a fantastic way to get into it because you know here's an image of
andromeda behind me right and again i took that with the axis 100 and just the
dslr and lens with wide field there's a lot of forgiveness there because you can you
your polar alignment doesn't have to be absolutely perfect it needs to be good and that because you if you start to do
the math i don't really want to get into it because it's really late um but but uh uh it it works out it really
does work out and then and this is the one this is the one i'm most proud of
um i took this uh as well last week and uh uh same
location up at the starfest campground um and this is cassiopeia you can see
cassiopeia here and i was able to i was surprised by this i wasn't expecting it but i got the heart and soul nebula down
in the bottom the pacman i got into the velocity here
i haven't delved into it to really figure it out i'm sure if i do a plate beautiful beautiful colors of the stars
yeah i was really really really surprised and again you know using um
a simple setup and i got this beautiful beautiful shot so you know i hope this is encouraging to people
uh that want to get into photography you know you don't need to get all this big heavy equipment
you can but you don't have to and you can get something beautiful like like this
to uh um that you know just wow yourself and there's so much in here
and when you start especially with the dslr you know you don't have to do these big
monster big long 10 minute exposures these are simple two minute and three minute exposures stacked them all up
after about an hour um calibrated it with with some calibration
frames work some software magic and here we go so you know quite happy with that and
and the missing with with uh with this is that was all done with such a simple amount um but yet
powerful uh also so that's what i wanted to i wanted to share i know it's not not anything to do
with the moon um or uh um it's all connected
yeah yeah it's on his face it was nice the moon was out of i could say our
theme is about black holes and you could show uh you know a solar flare okay okay
if i can get a picture somehow it's all connected if i get a picture of a solar flare i'll just be ecstatic
but but i guess we could say the moon health because it wasn't in the way that night and it allowed me to to get these shots
that's right that's the absence of the moon right yeah yeah there you go um but yeah no you know it it it's
interesting because um like i love getting into astrophotography and getting into the really deep space objects and getting
right in there right and grabbing the detail but sometimes you you know you get a nice wide field shot
like this and you see you see the beauty of of what what else is there in the the big picture like
even this image of andromeda it's not big and prominent like you have in some other pictures which is look at it look
at the detail in the dust lanes of that shot yeah but it it's nice to have
yeah the you get that detail and then you get to see everything else and i've seen some great shots similar to this where
there's so much detail just in in the spaces all around here right and
and that to me i think is just as much of a challenge this is fun um
to to do with with in astrophotography and the nice thing is that you don't need to have a lot of
really expensive equipment to do it this is a dslr a regular dslr um
you know it was a nikon d5600 not modified as bare bones
right and uh 200 millimeter lens and that that that's it right so you
know you just have to put the time in to get the images right i think maybe there's a couple of hours on it and
and then learn the software and then away you go um so yeah so you know i great scott thanks
for uh um not giving me a choice and having me on
that's right i'm gonna drag you in so yeah but well it was it was easy to have you
you just said okay you know so yeah i was thrilled i was happy yeah i um
uh but i'm glad i'm glad that i'm here and uh um yeah thanks
i know it's late there so um but uh thanks for coming on to the program and
uh you know wish you all the best with ontario telescope i know you're doing a great job there so thank you very much i
i greatly appreciate that scotty really do yeah that's great man okay well up next is uh
cameron gillis with uh cam astronomy and then um and then we we still have more after
after that so um cam you got the uh you got the the stage here
all right thanks scott can you all hear me okay oh i also want to remind you too that uh
cameron gillis uh has a weekly program with us uh called camstronomy and he's on
wednesdays um uh and uh he's he's been doing a great job
with it so i think you have quite a nice following of people that are learning uh
your sky survey method um thanks a lot scott and it's uh it's a real honor to be uh
part of this uh this fantastic team here i love the diverse uh you know all of my
predecessors i i i must say uh you know steve it's great to great to see that that's really
inspirational those pictures that you just showed right with the wide field shots that is awesome
um and then maxie of course i mean fantastic i love that animation of the uh you know the jupiter and and all that
and and uh just i love that that owl picture you know i could see why you'd go into the prone position that was awesome you
know i would totally and then caesar of course the moon i love it any live pictures
fantastic balcony master you know it just is really good i really love it love it you're going to join
i got yeah my wife cut my hair last week so i've lost a couple pounds there and then
john you know i love your your your narration of digging into the history of that that's
that's awesome that's a really deep appreciation and i love that and of course there's a whole bunch of
folks that uh are are you know molly and
and uh you know stella and i of course dave
david david um and uh everyone has just been fantastic and uh
so without being said uh yeah i'm i'm um i have my uh weekly so and i i've been
in the last couple of weeks here well uh while we had a little break uh we had a little bit of good weather here before
the smoke came in seattle and i got a couple of new pictures i wanted to share
they're going to be coming into my sky survey as well but as you know part of my sky survey
uh uh um um journey uh with everyone here is uh
is improving my astrophotography skills and uh and uh what i have
is let me just kind of give you a preview of this week let me just share my screen
and actually before i dive into that um i want to in in keeping with the
theme um of moonlits i i did want to share a few
pictures here oops not that one a few pictures
of um of the conjunction very very primitive this is with the smartphone
uh december 22nd last year and i actually got the conjunction
and you can see the four moons of jupiter a terrible picture as far as uh you know
there's dust modes uh it's out of focus you can see atmospheric dispersion but who cares
i mean this galileo would be thrilled
science picture literally yeah you know you know you have a the
biggest giant planet and the second giant planet behind it and
you like i said before the perspective of the
of both planets and in a single picture that's it's only science sorry
yeah it was just the thrill to be able to be part of that and at the same time
of course i was watching you guys do your marathon um and that was that was amazing i mean
uh with all the live pictures around the world and then even a worse picture i have here uh even worse but the the
significance of this is you can see saturn's moon titan uh triton here
uh so you have to blow it out of course but you know you can you see the the artifacts and it's totally overexposed
but you got all four moons of jupiter and titan it's kind of neat uh so uh
i just i thought i'd share that uh even though they're not really a world class but it's it's just neat to
be able to capture the moment you know and uh and share that so um
so now uh uh and i wanted to show you uh some of the latest pictures
that i've got um i as you know i've been working on calibration frames um
uh and and such so i've been basically helping with uh stacking and doing uh
better better images so here's a m13 uh it's i blew it up as well so you can
see the noise in the background but the reason why i thought this was neat is you can very clearly see
the propeller uh distinctly uh in in this shot and you can see that
of course the varying colors and the the full uh field of view of the m13 cluster
so and this is you know f6 uh sorry i'm using the f63 reducer on my
on my c8 and uh and taking 10 second uh stacked pictures
um this one here uh this is uh uh stefan's quintet and 7331 this is the um snapshot
uh that i this is not the picture this is just the uh screenshot of my um sky
safari and then here is the actual image and you can see 7331
almost like a miniature andromeda galaxy you could see some of its neighboring
galaxies down here companions and here's stefan's quintet so i was very happy to
be able to capture that in the same field of view and a pretty flat as well right i mean
you can see pretty evenly illuminated uh dark and um
with minimum processing post-processing and i'm able to get some pretty good detail with that
um here's a cute little galaxy i i was just as i'm doing the sky survey and part of the reason why i'm doing is to find
these little nuggets and this this is a a beautiful barred sky a spiral in um in
pegasus 7479 and i i love this the spiral you know
it's it's a little bit off uh you know i didn't do a very good job with my flat here but uh to be able to get
you know the if i zoom in here you can you can see some of the modeling and the spiral arm and and the clear bar
structure and that kind of a double arm here it's really nice to be able to kind of
take find these little uh nuggets as you're going through exploring the the
different objects here's uh you know everyone's very familiar m101 and the reason why i
show this picture is this is part of my learning uh as you know i don't have an equatorial mount right now
and even though i'm using flats one of the things i've discovered is if you this is uh this is many hundreds of
stock 10 second uh exposures i think is like 100 or so what happens is as the field
rotates your calibration your flat calibration frame is also rotated so it you you still have
a big netting effect so even if you have flats with the go and alt azimuth uh if you do live
stacking it's it the field is going to rotate compared to your flat and so that's going to make this uh this
big netting uh but you still get a good detail you know it's a nice picture uh if you can ignore the uh you know it's
not flat you get all the nebulosity some of the nebulae and so i'm excited i'm
on i'm in the queue here to uh to get an uh an ixo uh
sorry a nexus 2 uh with pmc8 with so at equatorial mount
and when i do these pictures a game where i don't have field rotation uh you
can you you can expect uh to see much better and i'm looking forward to sharing those those improvements but but
this is just a good example of you know another limitation of an alpha yeah once you're getting an ultaz is
really mind-blowing yes thanks thanks yeah and then and here's
m51 same type of thing you see the big name actually you see multiple uh you know starlink
satellites coming through but if i this is this is uh let me do this is a zoomed in picture pretty darn good
you know uh a picture of m51 um and no post processing except for
like i said just live stacking using calibration frames and uh and basically uh yeah and and not
bad again without has you know go to taking 30 second
lights you can see the stars around um you capture the arms
it's amazing yeah you you you get the arms and you get you even get this uh this little bit of a uh expulsion uh
from the collision of the galaxy so the interaction of the galaxies oops sorry uh so
if you go here you can start to see it a little bit better uh and then even this this piece here so
when i get an equatorial um i'll take a longer exposure and i i
really am excited to see uh even more of that um inter-galactic um
expulsion if you will okay when you get the the equatorial mount
prepare for the polar alignment [Music] absolutely you bet that's why
you know i'm going to be practicing a lot here even though i might have cloudy nights or whatever it doesn't matter i'm
going to pretend i'm doing fuller alignment and it will be yeah i'm gonna have a lot of uh fun with that
and i'll get that down right now with my go-to uh my three star alignment
i can be set up in in less than 15 minutes and i'm i and i'm imaging so it's pretty pretty good i
have my i keep everything lined up and i i think i can do the same with equatorial it's probably going to take
me an hour the first time but i'll get better at it and um and then
this one i'm really happy with m81 m81 when you see visually so here's here's
the the wide wider field you could see the nice delicate spiral arms and you can even
see some of the vessels and here's a zoomed in picture look at that i mean i am so happy even though there's lots
of noise you know it's not that's all uh you know will be improved uh it's
don't forget this is an uncool camera it's so there's thermal noise there so i'm fighting with that
but even with that to be able to pick out this delicate spiral alarm structure in ma1 really makes me happy i mean um
and uh and because visually of course you just see this and if you're lucky if you have a larger scope you can see maybe the dust
lane in the center here and maybe a hint of the spiral arm but but uh i haven't seen it myself
personally but um but it's nice to be able to image that here's m82 of course you have to take
m82 if you're taking m81 and here's a zoom in of of that and you
can see the very clear uh dust structure that's obstructing the middle here but i'm
again happy that the main thing i'm fighting with is the noise uh i can work on that um
when we probably need to take some more darks at appropriate temperatures because right now my darks are just one
set uh you know at around 26 degrees celsius and obviously i can i can do better than
that uh depending on the best way you should do it of course is at the same time as you're taking the
images kind of take some darks and then and process but i want to do live stacking
so uh so i don't have to do as much post processing so that's that's kind of what i'm my ultimate goal is so i can
continue the sky survey and record all these these will all be folded into my gamstronomy and here's the final picture
uh this of course with a c8 at f63
uh focal reducer at 1300 um millimeter focal length you're not going to get the whole
andromeda galaxy as molly said it's six full moons uh this is probably
one and a half uh full moons uh diameter but what i'm really happy with with this image
is the multiple layers of of dust lane structure you get including even near
the center here in the offset it's just beautiful to be able to see these patches of of dust lanes and and if you
zoom in here it there's even a 3d effect uh on the original image this is
compressed and and of course and it's put into jpeg after the original image you can start
to see even the the glow of the central bulge reflecting off of the dark nebulosity or you can see this kind of
uh reflection here it's really uh gives you a nice uh nice effect so very pleasing so i'm
i'm pretty happy uh you know not not definitely not a pod level but uh from a
sky survey perspective and the combined uh image technique uh process flow
and uh and sky survey um i'm i'm getting really pleased and i'm really excited to
be able to do uh the same with equatorial because here's another thing i'll say about
equatorial game just another pitch for those of you who are wondering you know sure you can do good stuff with
alphazyma but the biggest thing with el paso versus equatorial i would say besides taking longer exposures is the
fact that you can go right on the meridian above you so you're going through less atmosphere that's a huge
huge thing so all the objects that are directly overhead and and right over
you really like right now sickness is directly overhead for me i can't take any more pictures anymore of cygnus um
for example i had to take all those like a couple months ago while it was still lower on the horizon
and rising with my alpacas so that kind of limits you and it also limits what you can do especially planetary
as well but anyhow that's that and then just to end my my talk
um for tomorrow's camps astronomy for those of you who are gonna tune in or watch
the replay uh we've done all these objects we are now we've the last uh
constellation we went through was aquila and we were looking at a lot of planetary neighbor leather and if i look
at my my deck um we are
going to look through uh delphinus um
sagitta and vulpecula those are the three constellations and we're going to go through uh 16 more pictures the
combination of smartphone and astrocam and there'll be 10 new objects between those three constellations that would be
going through so that will be tomorrow's episode and then after that we're going to dive into cygnus and cygnus has lots
of juicy stuff so i have a whole arsenal of pictures and and uh
and stuff to explore but for now for tomorrow we're going to continue uh up the milky way
uh in those three constellations so and of course uh a little sneak peek the
last object we'll look at is the famous dumbbell nebula which i have a nice picture i'll save for for tomorrow
so that's that's it from for me so thank you wonderful okay
all right so we are going to take another 10 minute break and we'll come back um
uh with uh nico the hammer and pekka haltela and um
uh anyone else that cares to join in in the after party so um
we'll be back in 10.
hey cameron hey maxie hey she's there how's it going how's my buddy doing
fine good all right
i'm taking mate ccc with with something stupid something
something to eat [Laughter]
it's it's uh how does the line change uh you know
cameron we are we are talking with maxi that only max is only at 300 kilometers
from buenos aires but they call to the cookies we call it buenos aires the city
and the
we don't know why in the in the in the farm area they change and they call it
masitas why because massive is a dough it's another thing is something like if you
make the dough to make the you know the the the baker the bakery is
a very a sweet a bisquit and a very fine
biscuit and that's a was probably is a masa a masa
a fina but here
we say masita to a cookie a single cookie and we have this
um language fight from metropolis
did you do you did some planetary pictures with uh your
cw oh camera not yet not yet i i did try
because you know jupiter and saturn are up i i did take a snapshot but i've just been so preoccupied with deep sky
because um with the planets when i did take a picture uh i think i have them somewhere
um it just of course is blown out because i i can only go very short
exposures and there's just too much atmospheric dispersion so it it kind of washes out the picture so i the way you
have to do it is with the video like you say change the resolution go a higher sampling rate and actually
take the video and do it do uh what do you call lucky imaging right uh i i haven't set that up yet um but you're
right i i definitely was keen on it the thing is the pixel size on the on the 294 is kind of big um
so i'd have to play with the image scale maybe use um i would take out
my f6 three focal reducer for example go to the native focal length of 2000
and then and then i don't have a barlow but i'd have to do that eventually but
at least i could do that and then what i could do is i could play with the back focus probably
and uh and because you don't have to worry about um when you're just taking the image of the
planet uh you don't need to worry about the field on the edge so you can zoom in in
a way right you can bring it in bring your image circle in so i i will probably play with that but
um i'm just enjoying having my my scope all set up
not having to change the image train and just bringing outside and it works right but
uh but uh when i get another scope i will be getting another one i actually have my mac 102
that is beautiful for planets it's a mach 102 uh with uh with 1300 focal
length is really excellent and in fact i that was one of the things maxi i was
going to do is set up my image stream because it has the adapter it has native
threads on the back uh m42 threads and i can actually screw down the camera directly
and uh it would work uh probably pretty well so i'm gonna play with that but i'll have to take new
uh i'm just wondering with planetary do you need to take flats and stuff darts
but i i don't i don't use that uh yeah when you proceed
maybe you you will have some dust when you in the in the sensor if
you try to clean it and also if you using a part of the lens also you will see the
the the dust modes and it's very
annoying but yeah yeah if you try to when you start to
take the videos and put the a place where it doesn't be
dust it helps you when you stack them and you will not see it so it doesn't matter
but when you do the video and you have some uh
that some dust now it will be in this tag and it will be uh ruin your
your picture yeah and also
in the planetary pictures uh you you must must have
the the rotation process is
because of course jupiter rotates very fast and
in in one minute uh it changes a lot and when you stack
most of that minute and also if you're using a very very
far focal length uh that movement will
give you the um the the surface will be blur
for the rotation uh so you will have to do
a more in frames to stack in a very short time
to get the most lucky images to stack and then process and then do the
rotation it's another kind of astrophotography
yeah i've been watching a lot of the um uh you know christopher grow uh yeah
he has a lot of awesome stuff from last year what he did yesterday
two days ago with stupid then you know he he captures
the the master
eclipsing europa at the half and that shadows
uh it was um projected in the surface of the of jupiter it wasn't i did i didn't
i didn't see that one i got that i got to look for that yeah you mentioned search it okay i'm gonna find that thank
you thank you okay you know because he uses a thing called he calls it win
jupos or something like that yes and it does that derotation for you
and it does it spreads it does the lucky imaging and it can figure out uh the rotation of the cloud belts and
then find that the stack the appropriate lucky image so it's very complicated but it does all that for you so yeah the way
i see it in the string oh you have a new analysis the limit is like you see actually f ring it's actually even more
dynamic than we thought oh first time you can see some of that objects about a kilometer in diameter
this movie shows the trail of one of the 500 or so tiny objects that we see punching through parts of the f-ring
we've highlighted the area where these trails can be seen these are slow speed collisions perhaps
just a few meters per second but they drag these glittering ice particles out of the airing with them cassini sanders
have been calling these trails mini jets they look tiny because in the full image
you're looking along about ten thousand kilometers of the f ring oh there's a little serendipity involved
we're actually concentrating on prometheus what we didn't notice at the time was
one of these tiny little trails has sort of sneaked into the field of view but now we've done things a bit more
methodically we've actually looked at about 20 000 images and we find lots of these little guys and some of them we
just caught in the act so far we've seen about 500 of these objects in the cassini images some of them may even be
the same object what's important about these images is that these little guys are the missing
link we know what prometheus does prometheus creates channels ripples snowballs in the airframe but what we
didn't know is what happened to these nobles after they were created we know also that prometheus can probably
destroy some of these things just like it can create them and can also change their orbits
but now we've got evidence that some of the little guys actually survive and they go on to punch through the f
ring on their own essentially we're taking our images of the f ring removing the planet and
exaggerating the radial scale thanks to cassini we can study all this activity on the f ring over time well even during
the time that cassini's been at saturn the f ring keeps changing it's the only thing you can rely on the f ring every
time you look out over lucky imaging [Laughter]
imaging perfect
hey pacquiao good to see you good to see you too hey pika hello maxine how are you buddy i'm so
great so great all right awesome good to hear yeah excellent
that's it's nice to see you at this hanging in there so yeah um nice to see you
yeah paca great to see you man so what what's been happening in stockholm
what's what is uh really almost nothing or it has been
so stone death by the astronaut front i have
tried to get some images with my dslr for the northern sky
and i could capture without any tracking and with
one second exposure m81 m82
and they are there but just just to try but this is a low
quality objective i'm targeting to get the samyang 135
f2 to win the season so i can take my
star tracker to the inner guard yeah and then i can do a good poll
alignment and uh try to get those and m 101 also because
the norton sky is totally new for me it's unexplored
uh part of sky for me totally oh wow okay and um
my life have been changed radically the latest time
so now i will make my
bedroom to an observatory room so it will it will be
like ambient uh temperature in it okay
and i get i have a g5 mount that i can put so low that i can color
alignment okay and how it's like uh to the north and skies
uh so i can make some
good images with the tracking so your scope's going to be mounted
inside your room yes with the open window with an open window so like a guy
in uh it was in singapore i believe who um who had a telescope set up in his room
yeah his mount was pushed almost all the way to the wall of the room
i have to do that well because i think the g5 mount the tripod is made so you
can have it so two old eggs are in the front
yes so i get it but that way i will get it i think i will get it some a little bit
closer to the wall because my polar polar star is 59 degrees
up so the angle is so narrow to not to hit the upper level of
the window yes so i i have to measure it so close
yeah to the uh otherwise i have to buy a pier
somehow to get it so close to the to the wall yeah
i can reach polar polar star that's my plans
for northern sky okay so there is happening things uh i have now uh one american king size
bed there yeah so i i if i put it on the one wall i maybe have
uh enough because i will open the window
a couple of hours maybe three hours before so it will be like outside
sure with a big window as a front to the skies but
that's that's like a kind of a new horizon for me
completely new stuff are waiting for me that's cool and that's great it's an
exciting project yeah that gives me like 40 percent more sky than i have today
and the light pollution is that's light pollution on that side i
only have a one skyscraper but those lights are
almost like off at the night time so that is
quite i can say that that side is portal
six and the south side is portal nine or eight
so i will try i have some spots that i will catch try to catch
m82 m81 and m101
that's the target for this beginning yeah yeah
but i have my i have my inner guard that i can put my star adventure
and i have a seat you know those uh
park seats yeah and i have my
my porch or stairway [Applause]
like uh where do you have elevators and stairs because this is a complex
so i can sit there in the world yeah and and and i can see my mouth
so that nobody stays it so it's only five meters out and i can sit
there inside and watch it so that's the plans but uh
right now stem death we have sub we have so bad weather
oh for a couple of weeks yeah but you know what when you set that
up that's awesome you know what they say when a door closes a window opens there you go you've opened another window and
and you're you're at 59 degrees north right you're at 59 degrees north yes i
just checked you out on the map on stockholm and uh and that is almost at the arctic circles you can see uh if you
have that northern sky you'll be able to see everything yeah right so everything
they're missing in the summer even though you have a short night no night but in the winter it doesn't matter
because you're going to make up for it you're going to have awesome you'll have everything like you say you'll be able to see m8182 and 101 all
the good juicy stuff that's going to be great yeah that is cool completely new for me that portal sky oh
that'll be exciting though so i can try that
because i can take my mini computer my mini pc it because it's on my platform
uh i can put it on on my bed and take just connect
my cameras in that scope so this will
be very exciting uh fall and coming winter
so uh let's see oh we have to get um a nice uh tour of your new uh yeah
uh yeah and then i get some news from my astro
friend he knew very well
the director or how do you say of stockholm
observatory the main observatory and we will get the private
toll next week right and we will see the 60 centimeter and 50
centimeter refractors and uh everything there and i will make
i will try to make it like a documentary and i will text it the
movie i make for english so you can see it the upcoming
events star party excellent i will collect some information about this observatory and
the observatory moved outside stockholm very near a sea
because when stockholm was growing up the city lights became uh
too too bright though yeah they moved outside
on the very very near sea because uh what i read
when it see like a humidity it's better skies and lots of
less light pollution but it's hap because all those control panels are
from like 50s 40s so they are still there
the original stuff so that's heavy and nice so i will
make a small documentary over the new stockholm observatory
yes that's cool awesome excellent i love it yeah we'll be waiting for that yeah we
have so we will some evening next week so probably i can get
it done for from two weeks now
number sixty yeah perfect yeah number sixty stockholm observatory
and then we go on three years i i can make one over shift observatory
when it's open for public apartment i mean
right with you observatory rooms okay thanks guys
yeah thank you very much becca because something that um uh reminded me of of some of our
conversations uh was a posting that david eicher made uh earlier
earlier today yeah i saw it yes yes and he was talking about how we should show appreciation
to the sun you know yeah and basically he said just a reminder he had this beautiful image of the sun
and you know he said just a reminder to appreciate the sun today especially if
you have a cloudless sky without our neighborhood nuclear fusion reactor just 93 million miles away we would not be
here you know exactly and uh uh he's absolutely right and it made me think
more about the sun and um just kind of the uh and we you and i talk we've
talked about this many times back up is people's narrow narrow view of the world
you know they yeah we get wrapped up in our um uh you know we hear about uh you know
some senseless tragedies on the news we hear you know we get caught up in our
the dramas of of our you know maybe our daily struggle but and and we
think that that's our world you know when when in fact you know you we are
you know orbiting this star and traveling through space at incredible speeds
i think that i'm often reminded that
stargazer backyard stargazers and amateur astronomers have uh
you know they they are they have a
advantage to uh relieving stress in their lives yes
absolutely right we say it's a cable to to the ground but i think it's a cable
to the sky yes yes your mind uh
unpressured i think well you know it's a real connection to nature i mean
you know everyone likes to go to camping or go out to parks and and enjoy you
know nature um but this is the ultimate raw nature i mean this is
you're looking deep you're looking the 99 of the nature yeah you're looking beyond so whenever i
say that yeah when you're looking through a scope for i i just really enjoy like i i enjoy
you know that we have the the birding uh show for example that's beautiful looking at landscapes through telescope
or binoculars and now you're just now you're looking at nebulae right or galaxy it's the same thing it's just a
different just you're looking deeper that's all you're just and microscope same thing right i mean you're looking
in different ways but it's all you're you're appreciating nature through different lenses that's right that's
right this is the view of the this night like i show you before here's the moon
he's a halo because the
the clouds but here's the scorpius antares okay and the
side of the scorpion yeah right i don't get the feeling and also
here's a alpha centauri oh yeah
and this is only a very short a picture of i think it was six seconds
and it's so uh 400. i put it a about a a
a backyard chair and take the picture and this is what i i take
and this is the the perspective that i spoken before
here's the the the moon more beyond it was the saturn and
jupiter and this is was my five minutes a
blown mind to to reconnect with the nature basically
yes yes yeah and also for the view of the halo i
love to see the moon in the halos like that you know it was very circular but i couldn't put
put it very good the phone because but it was very very it was a perfect
circle and it doesn't work and it wasn't a full moon
this was a genius almost
a planet you need uh alpha centauri and uh and the large magellanic cloud
and you have everything in one picture
i think in two months well it will be more
more earlier because it's more from the summer skies here and
now we have it very down to the south above the the horizon
and it's will very late when comes very up
but uh yes i hope uh take again pictures of
of that place uh and this is my
final collimation i don't know maybe of course you have a lot of experience in collimation telescope this is the f4
i was fighting almost from 8 p.m this saturday
to almost 3 a.m let me get more closer okay
and i couldn't finally put it and i went to sleep
thinking about it and wake up thinking about the collimation and my wife said
what are you doing i'm still condemnation um
i spend two hours more and and i think i can have it
you know because here's the offset and yeah i i
know in the f4 it has to be more exactly and it will be this little more
notes very circularly but here the the focuser you can see it very
surrounded with the the primary mirror yes i was
i don't know very really and
i couldn't try to get with the stars
because i i have a separation in the spikes when i get a focus
and and i was very upset about that and i couldn't find it but i think
i will not touch him again uh but i think now is how to
how can i put it in a in a good place
and i think it's very central to the to the focuser
the the space and this it was a with my cell phone
i put it uh the the smartphone grab
trying to get a very center of the center of the focuser and
then i connect by usb to my pc my my computer
and i use a program that calls a droid cam that allows me to
see the the cam the camera of the of the phone in the pc
like a webcam for example and i was
you know with a live view watching uh and do the
the adjustment because uh with my own eye i
oh we just lost them yeah he froze yeah
yeah calling some netflix movies collimation is not nothing for uh weak
nerves yeah exactly
no i i've done my fair i mean i i had an 18 inch job and bro i can tell you that you can get pretty good at it
what really helps i i must say what you should have is a laser collimator if you have a laser
collimator you can get you can do it really not bad so maxi did you use a i think you're
back now right yes i'm in baggage yeah again yeah so did you did you ever did you try i know
you did everything manually but uh did you try consider a laser collimator i i have one
i have one but that laser collimator it doesn't help
in the position of the secondary mirror
because uh it's not like a something is a collimate
an f5 telescope where everything will be going to be a perfect circle
but in the nf4 is completely different
yeah i'm still from march trying to collimate this scope
wow well you know the the thing is um it might be a yeah
there's lots of factors i mean uh scott who knows a lot more of this of the
mechanics but you know the size of your diagonal and the angle at the diagonal and
how it's centered on the spider you know they're what you should have is a dot on
the center of your your your right angle your your um your diagonal there should be a dot in
the middle and then you have to have a doughnut in the middle of your primary those have
to be perfectly in the middle then when you do you do your collimation
you can if you center that axis so it goes right down the draw tube then it's just a matter of rotating
each of those uh you know the the the diagonal and the primary and that will affect the uh
the the flatness of the image you you you must get that center line
perfectly lined first that's the most i i couldn't [Music]
i couldn't go ahead and take it because uh when i tried to put it very very center
i still have that separation from the offset and uh
it doesn't work very very perfectly and
my my hands was like a worker trying to adjust it it's
easy to you know when you're you're trying to collimate the secondary and the primary
it's very very easy to get confused and lost okay and all of that
uh when i first was being taught how to collimate newtonian telescopes this was
at meade instruments and uh they put me on the assembly line to
collimate uh a bunch of um 10-inch uh newtonians and uh
you know so we had to do a hundred uh 10-inch newtonians that day you know and
um so so we started out we started out with uh
uh the uh secondary assemblies already put into the tubes okay
uh focusers are already built onto the tubes at this point but the primary mirror was off completely off
and that that that the tube assembly was on a um we just had a uh
an assembly to hold the tube you know uh two v blocks and
the way that we collimated the secondary is just to look at a white wall
okay yes and to adjust the secondary so that the secondary was perfectly round
underneath the focuser oh okay yes perfectly round underneath the
focuser and um uh and then we looked at the
at the tube itself okay just the black inside of the tube against the way wall so you just had
kind of like this white spot okay you didn't have another reflection to look at exactly okay
so the whole job of the secondary is just to get all the light from the primary up to the focuser and
for that to be centered so if you get that done then you can put on your primary again
okay and you're finished okay
so uh and maxi you're correct in that uh the faster the system is especially now
they have my god they have you know we have 2.5 we have a 20 inch f 3.6 okay
newtonian and it's got a big secondary to capture all that light but you know when you have when when you
have the uh short tube short focal length you have a big secondary and as you drive that
secondary down inside the tube okay now you've got okay think about your cone of light all right
and if you got a big secondary that tip this down here has to capture the other side okay and
it's way down and this is way at the top so that necessarily makes it offset okay
and so on a longer focal length like an f6 f8 newtonian you you have a much smaller
secondary and now you're starting to get everything like centered up as you described cameron okay where everything
the center of that secondary is is centered on the center of the the
primary when i personally do collimations i i don't like to use the donuts and and the
dots you know i i will then take i'll get it as close as i can
uh uh you know with maybe like a um a canister that has a pinhole okay
so i'm i'm dropping that in like an eyepiece into the focuser i'm just making sure everything's lined up then
what i do is i go out on a star and i throw in a medium power eyepiece
make my throw it the image slightly out of focus collimation diffraction
then i go to a higher power eyepiece and then a higher power eyepiece and the most high power eyepiece i have okay
and i make final touch-ups with the star dead center and uh that always does a great job oh
yeah you can't be bad that's that's awesome and that satisfaction afterwards i
learned how to do this all before you know they had laser collimators and all of that yeah
of course the optics it was uh from centuries
that i i i'm from the amateur and
uh i didn't even
i i have a newtonian scopes like two years ago i have the ef5 that now
has a nico and that was very easy i put the lasers try
to be very circular and also in that scope i personally changed the the
the the focuser because it was the the old one that has only one point one
point 25 inches uh to put the the two inches find a
focuser yeah and i i was with a a little
a cutter to to get very circularly in the garage a
very a homemade but it fits perfectly and it was very central
and it goes okay but in this case with an effort it changed
me the the perspective of everything so it's still consuming
oh yes i i searched in english forums in cloudy nights in
uh i don't know in pasio profundo a forum from argentina
if with the the another one did a very good collimation of the same
scope but i don't have the those uh tools
and i you know in that post is say that
it doesn't it wasn't an 8 inches it was a 7.75
inches it was a little smaller that f4 and the
the the center that was marked with the donut it wasn't central it was
almost a the size and with the i think it has a cat's eye
a tool to to get a central and unchanging and preparing but i don't
have those tools but i think this time goes okay and i hope with very good
conditions to to try again with the dclr
yeah i think actually maybe it's got to confirm this too i think you can actually there are multiple points of collimation
but it it's it's it if you may not have full field uh illumination you can collimate i think
you can still get the uh the full collimation but then it then you might be cutting out the cone of light
on the edge that's the only thing right is that fair scott i think you can get collimated in
different places it's it's uh but if you're just looking at the reflection of the mirrors it really
throws you off especially on yeah it's that secondary okay
the perspective it's easier if you pull the primary mirror off
the scope okay and you um and you just aim it at a white wall okay
so you're not looking at all these reflections in there okay um
you know there's another tip too that i can give you uh when you are
especially if you're looking at an out-of-focus star is you
hold your hand in front of the let's pretend
you get this new shield here this is buzz aldrin's dew shield off of
his telescope so we can a master yeah
then there's there's a spider here okay and and the focusers on the side of the tube
okay yes um uh when you're looking through the focuser at a at a star okay at high
power you can then put your hand into the the field
and as you look at the autofocus start what you see is a little slice of shadow okay
where your hand is okay so if this and then what you would do what you do is you move your hand around
like this okay until your your the shadow comes against the thinnest cross section you know because
if it's out of collimation uh you're gonna see that uh there's a wide
uh band of light and a narrow band of light try to put it at the widest or the
narrowest in the band and then what you do is you go okay let's
say that this is the position then what you do is you look back on the back of this the newtonian telescope
where the collimation screws are okay and your hand will be pointing at one of
the collimation screws or between two of the others so that's the collimation screw that you
use to adjust so you're not like guessing which collimation screw you got exactly
right that's a perfect tip you know that's a great tip it speeds up the whole process really
fast so
a lot of fields that you played it's like a
a lot of experience so you play a lot
it works on any telescope so even on refractors you can see uh
the the shadow of your hand uh at either coming up to the thickest uh width of the the you know the light
or or to towards the thinnest on refractors you don't get the you don't have the advantage of the shadow of the
secondary and so what you have is is you have a bright dot even in the out
of focus light okay and then you can see the the concentric rings okay
the area right you see concentric rings that they're not the diffraction rings to the
fraction this is not a focus this is out of focus uh so um i've heard him described as
front offer rings okay but nevertheless these are the these are uh rings that are um
that you know that uh occur when you are looking at an out of focus image uh
through a refractive lens and you also see them on a newtonian telescope too but they're really those
they stand out on a refractor uh and then that shows you which screws you
have to go to adjust on your refractor and collimating a refractor
is not harder than collimating any other type of telescope you know
and i think that you know it it helps if
you learn how to collimate your scope uh and not be afraid to get in there and
adjust things you know now if you have an observatory you can have the telescope collimated you'll probably
never have to touch touch it again but if you were like me and i was bouncing with telescopes out you know as
we're going out to the california deserts dirt roads
uh yeah we would have to call them at our telescopes almost every time you know and i just got uh share a screen i
don't know how many of you have an and uh smith crashing game but i thought
people if uh cameron is interested to see this if you have
if you have seen this collimation uh short there i haven't seen that uh combination
chart but uh but i had collimated my
cast agreement it shows it shows because the these are the collimation uh
screws yes and if you see that the
is off of there then you have to screw the
screw you go to the screw right directly across from it that's right
yeah and there is a ccv is counter clockwise you turn
the c screw counterclockwise yes and this shows that all the
collimation uh if it's wrong very strong and what
screw you have to screw and what direction this is true but on a schmidt castle
grain both celestron and mead schmidt castle greens that that collimation mechanism is not
spring-loaded okay no you see me it's held in place so
you've got one screw you might be pushing out okay or unscrewing yeah you
got to go counterclockwise but you also have to come in now tighter on the other two
otherwise
doesn't stand there and i have not thought about
i loosened it up it looks great now as soon as you move your scope itself out of the sky this part of the sky that
secondary rocks on schmidt cass green so like an eight inch f10 telescope or tennis f10
you have a two you have an f2 primary okay very very fast primary
yeah and then that secondary is a five power secondary okay
so little tiny moves you're you've got it's magnified five times okay
[Music] very small adjustments okay
and uh and i i got mine it was almost spot on so i took a picture
with my dslr yes and then look at my computer screen and took and
you know this uh what do you call it this uh
measurement stick um me as you read oh yes
calipers caliber all rings how much between they are
on opposite side yes on a fraction of millimeter
yes so uh yeah i actually i succeed but i don't like to
do that many times not on a cold night and i bought an
artificial style but i have a problem if i have to put it on like
60 yards at least 50 feet 60 feet
from my uh my tube and it has to be on the field
and if i put it on i have to have somebody who tells me
how do i angle the the artificial star
and if i leave that there and turn my back
the mouth tripod and the artificial star is gone yeah yeah bro actually that's the
other thing even even if you have a high power and you're doing collimation with high power
then uh as you're collimating this goes way out right it will move yeah yeah but i have to have a friend
with the phone or top walkie-talkie that i can say that okay those have to be lined somehow because
otherwise they very tiny light beam don't
light in my telescope so yeah let's see this is the next second
second season i will do that but it will be fun again yes it's like butterflies in my
stomach and it's like my fingernails are almost ready to
to begin [Laughter] so you know what we there we got to have
a a kit it would be nice to have like um artificial star kits or something like that
for for many of us who have cloudy nights we got new gear you know and we and we want to test out
new eye pieces and stuff nice yeah yeah that's a very nice thing
because i've done that with down my hallway my hallway you know probably it's about 30 feet
let's say 10 meters right 10 meter is enough to get in you you can focus uh
you can you can still focus uh i i i focus both my
my schmidt casagreen and and my maxitoff i was able to get i made my own
artificial star just by making a pinhole uh through a piece of black paper
and then using an led light but it's it's limited it's still not diffraction limited so you you
you can still resolve the pinhole my artificial star has five different uh
sizes of uh holes the smallest one
is like 50 microns
so it goes from 50 microns to
one or is it 200 or but it's tiny so you can
but i haven't used it because i need a friend that holds eye on my tripod
otherwise it's gone you have to just walk home then where is that
stock and it's for sale but the next day it's
unsaid on a magazine but i really like scott's uh technique
you know yeah it with a newtonian that's an awesome way with just a with a real star if you have clear skies that's the
that's the most most satisfying right it's it's it's right there you're getting the improvement as you see it so
maybe maxie you know hopefully you got some good weather try that out you know you have the pictures of course
why don't you just it's right out you know so i have one
that i have even touched and that newtonian has a
really fun story uh i was after this um
this celestrons uh uh phone holder oh yeah next yv yeah yeah it was
sold out everywhere yeah nowhere
and it was impossible to get hand on and then i saw an
advertising and from celestron 130
newtonian with mount yes and and that one
and i call him and i was only interested in about the phone
holder no no it's a package okay i have to fight
by the whole thing so i have a
the amount of it it's now the amount for my uh
my star adventure and the tube is like
okay i can uh so to kids and so on or uh make a giveaway to some uh
young beginners that maybe have a mouth or something
when you are doing pictures you put it outside and and do some observations
yeah i haven't used it yet so i have to try it could be some good
for some lunar imaging and so on but
we have had some bad weather so but you know when you have clear sky
you don't start to test some some
some equipment that you that don't you you use those minutes you have clear sky
for real stuff and collect and collect some uh important uh photons
and uh and observation and so on so it's hard to make uh
like play around so every every single uh
clear sky is like uh it's planted in ahead
when i make my weather reports okay that evening is like booked with red
without without moon yeah all all door locked and phone
off in flight mode
so yeah you know i i searched the
the the the tracking of that of the camera and now
it's on the way and he went out from the center of angaraj
alaska so he's in america continent and i think
i hope this weekend maybe we'll come to argentina
one month was it a night two night four
uh no then the five
yeah so i will try that maybe to get galaxies
and the f4 but i also
maybe will need a in the future a a very short maybe a
an apochromatic refractor because i like some medium
[Music] pictures maybe of entirely of
of orion or or
and that camera maybe for the the size of the sensor
get me very soon with the f4 so maybe with a a very short telescope in
the future and another mount will be great
what what maxi it looks like it's a is it an eight inch or ten inch f4 what
is the size uh i think it's a eight inches but
uh for the post that i saw a couple days ago uh with the cat's eye
um platform to to calculate the size of the mirror the primary mirror uh site it was
a 7.75 inches yeah that sounds it looks like that i
was just looking at that just when you had your smartphone picture there of the down the tube it
looked like around that size so that makes sense that would be good you with that with that focal ratio you're
going to have good wide field and right yeah yeah i can see why you want to collimate that because when you do the imaging
right um then you might you want to see the spikes
very flashing but when you see doubles what what the heck
what's going on uh yeah well that's called animation
yeah actually the spider in that case maybe the spider is not perpendicular right
perfectly perfectly perpendicular that could be the way you have the spike when you
turn the the screws maybe rotate it yeah yeah
so you have to put it very here or listen so yeah okay let's see what happens in
the computer the ongoing uh saga i like it maxi good project good project so you
have a good um pekka has a a good project on the uh on the observatory with the northern sky i love that and
then maxie you have the the high speed uh and then i have an equatorial amount
i need to get yeah so i will need maybe a model
in the future i i would maybe i would buy a in exo's 100 or something because i need
a a very a white equipment uh i
buy it but i sold it it's nico the aq5 with a
fa5 telescope so maybe in the in the future to to go
to a farm place or to alberti or another place i don't know if i will go to the uh this
month because it's very heavy and no no i i
maybe i i don't know next year about it yeah i mean look at maxi and steve malia
they they use the xs 100 that's a beautiful amount i mean yes i mean even though i'm getting the x was two
initially i'm thinking if you've been getting a nexus 102 because that having a lighter
mount and having that comparable it's really it's it's very slick yes
it helps you a lot and then you need the g11 you know you need them all [Laughter]
when you when you get the c14
guys i do have one really of my topics what i have thought
uh connection with universe that's my topic so why don't i i have one i do have one
uh what i have taught that how we could compare
astronomers how we see the universe compared to
people that don't see it like we do is a
paddle male a paddle with the letter okay somebody found it after 20 years it
will be almost word news it was a huge thing that somebody found
a bottle with the note okay that's a huge thing locally
country-wise but when we see a comet that has been
on his way like million years fly spy go around sun
and nobody says nothing
yes yeah sometimes um
sometimes the news the media doesn't present things
in a way that you know really gives way to the importance of what it really is you know
this happens a lot and over the years uh i have seen the media
get better and better okay and accuracy of things and
presenting things but there's a gentleman his name is phil
plate you probably have heard of him he's also called the i think he has a site called bad
astronomy and so he critiques movies and uh news media and uh anything that's
pretty much put out there and it gives the uh you know from a scientist's point of
view uh uh you know he facts he fact checks um
uh you know these what's put out there and there's uh
sometimes uh the information that's put out there about astronomical events are quite bad you know so yeah
yeah i think it's everywhere unfortunately i think that uh
normal pew people they are they feel their safety
you smaller the area they are involved
they safety they feel them because uh
i have found that in the news and the reaction of things
that if something small happens near
to get people to know same fear
uh wonder or of any any kind of emotion
it has to double or triple or ten times or a thousand times you longer distance
that happens so if we have a earth shake or something
in sweden to get earth about that
the same reaction that i have the same reaction
has to be ten thousand death in china yeah yeah yeah so the distance makes
uh makes just connect yeah it has to be larger amounts something
we we don't uh the this is uh this is the problem of boundaries and uh
the separateness of things that humans do you know we separate everything we
separate our roads we separate our neighborhoods we yes even if if you work for the same company but if you're in
two different buildings okay that's two different building fields yeah that
they're somehow a little bit better sometimes than the people in the other building exactly exactly and i think
that many many times you know a small basis you know
and i think it's good that ours devolve we say
yeah the this fear we see so many things many people are thinking that is a
people it's just fair yes that everything stops there but they don't they don't
they can't tell how far that is it's very near or very far away right but they that is
there but the they don't think that it it don't stop there
it continues it stops there that's it's it's it's really just the beginning right
yeah it's um and there is nothing to compare with
like uh i i like to
teach my nearest i think
how i think but it's it's hard to
you have to have a key first to open their mind that they can't think
freely and not like they use
in the box yes yeah it has to be balls and that's my analogy is is is actually
filters i mean it's it's really different layers of filters right we all have filters on
uh you know and and you build filters as you get experience as you grow up
yeah based on your social environment and all that and that affects your filters right and
when you have those filters on say wearing a set of glasses and it's the same as our astronomy we
when we do light pollution it's a filter you're creating another filter to prevent you from seeing certain things
yeah and so so to your analogy uh you know
when people look at the message in the body a bottle or the media covers a certain thing it's it's because certain
filters they're they're attracted to the money filter right yeah the money whatever gives the most money and it's
like okay the money filter is very powerful and uh it biases a lot of people and it
automatically cuts off certain things that would be really like nature which is
free right exactly and and and and then people ignore
they may might even ignore beautiful sights in the sky like even a sunset they don't even take it for granted
so there's so there's only so many sunsets we can witness the importance
that it should be yeah yeah yes exactly and so you know
everyone talks about it the sky doesn't give any value to their lives
so that's that's not important take it for granted take it for granted
but yeah my wife and i we went for a walk you know the other day and we you you see uh the leaves you know in
the fall right yeah and you and you start thinking we're getting older now and we say you know
we're only going to see this these leaves these colors of the leaves maybe 30 more times
in our life for example right and and and when you put it in that perspective you really
you really want to appreciate whatever you can see yeah you know framing your perspective when you do that exactly
yeah yeah and i i think you know
the prospect of um of people being able to fly into space
as a tourist okay i think that um i think actually i think it's pretty
important because i think so too you know if the people that have
astronauts that have gone into space they get that uh that overview effect you know where there's now they're they're looking at
this planet as if it's this living thing you know a single living thing you know and uh
they don't see the borders anymore they don't yes that's why i always say see you know it's this beautiful
blue uh orb that's out there and uh
amongst amongst is you know a vast darkness you know yeah and only floating
there yeah and and many of astronauts they became
directly after first step on the earth they came like
protector protectors of the earth yes they they just
turning it around and they became to protect the earth
and i think everybody of us because i saw a documentary how we
how we treat our trees and that's our
earth natural producer of rain and
oxygen oxygen and taking off the coal oxide and and so on so
yeah we have it's it's too much for one
but one cannot do everything but everyone can do something
that's true that's true even discussing it is uh exactly very
important because um not only in our own minds but uh you
know people that hear us you know uh um you know they they may they may feel oh
it's it's a little strange or they have they've got a little cuckoo or whatever
from yeah at the stars but you know the the the the thing is is that uh
when you start to put uh some of the pieces together of where we are in the
universe and you know start to understand the vastness of the universe distance
scale the scales of things and and all the rest of that it it starts to
you know i notice with many people they come out at a star party begin you know people
never observe it before but they're out there maybe with you you know an experienced uh observer
and you start to tell them okay yeah you're looking at you know uh you're looking at uh this
globular star cluster and there's 500 000 stars in what looks like that
snowball of stars you know yeah and it's it's uh you know it's it's 30 000 light years
away and you're looking back into time and by the way we're moving through space at incredible speeds and
you know now they start to get they start to feel humble because now they realize how physically small they
are you know yeah um i've heard many different kinds of reactions from people
uh in when i do at astronomy outreach one of them is the
effect of someone feeling very humble very small um uh
another one is uh people that become afraid you know they'll see like uh
they're streaking across the sky and and uh you know and it's very possible we could
be hit by you know a large asteroid at some time you know and
and that would be you know the end of of uh most of life
on the surface of the earth yeah so that's uh um but there's this life deep in the
earth that you know the sea world is another one the
impactor took out the dinosaurs i mean just utterly destroyed the surface of the earth right yeah
we are and i think that's an overview effect you're talking about when you when you even when we look at other
planets and you know kind of putting in david eicher's geo geological view
the the molecules that make up life and and make up minerals are very complex
gold and and and all the heavier elements that were made out of stardust right and
explode very special uh events and when you see them concentrated in these rocks
it's a it's already a special gem it's like you know you found when you look at jupiter you look at mars it's like this
is a diamond right it's like a it's like a very rare and precious uh entity and then when you look back at
earth and you have life on it on top of it all right right it's it's like wow you know what a beautiful thing you you
look at it as a whole system and and it's like wow and then that's
why we want to look for life outside of our solar system right and and and because we want to see we
want to look for those gems right i mean that's it's a very special thing even though life
on the universal stage scale might be abundant in the universe it's not so abundant that you can just see it next
door right i mean otherwise we would have found it by now it's it's abundant but it's the distances are so vast so when you do
look it's the same as when i'm doing my my survey when you
discover a different shaped galaxy or you know or different uh you know feature on a on a planet or whatever
it's it's so exciting to discover that unique thing right i mean
it's it's just thrilling and and it's it's nice when more and more people uh start to get that appreciation and i
think that that as more and more people get exposed to that and uh i think
you know with our today's technology it's becoming more and more uh you know possible
that people will start to gain that appreciation more um i mean even even the fact that so
many people have smartphones now look at how much that's changed things i mean people are taking pictures of all
i've never seen so many pictures of bullets you know and you see them constantly now
there's like oh yeah you know somewhere in russia or somewhere in northern europe or west carson russia captured uh
yeah uh you know that small asteroid that plenty
you know so yeah we're just and this only happened recently right i mean it's uh it's not
happening at any other time in humanity right so exactly yeah and but it's it's
it's a common thing right it's it's just we now have the cameras and surveillance
if you will and that that turns in conscious into consciousness i think more people
it becomes more the media will cover it people will start to talk about it and
then they start thinking yeah you know there's more than just our country or whatever
our borders we we have there's the universe whole universe out there that's that's happening uh
remember the next year will be in orbit the james webb telescope
i will give you give us a huge perspective of
how they will culminate the telescope yeah yeah if they have a problem like they did with the hubble and it's like
oh my gosh small space space to the breeze make
correct because they will maybe they will call you to culminate
the scope [Laughter] yeah just just remove the primer [Laughter]
no no it's uh it it's going to be awesome uh maxi i mean that that james webb is yeah it's
it's it's a whole literally borders of magnitude more than the than the hubble it's it's gonna be
groundbreaking yeah i think and i hope to be a
there will be a new era of perspective of the universe uh i think
from my my future i believe i believe the more um
outreach that we do in astronomy that we are you're waking up people
yes yes little by little and um you know uh i i believe it does help i
believe it does help i think it makes people get a new perspective uh that reframes
what it means to be alive in this world and and what you're supposed to do
you know i was just pre justin and you said that scott i was thinking that
we do also have a small responsibility each of us
to show if they if if i see some smallest interest
i have to i have to pick up directly and make it
true for those that they can see or ask questions
because uh i got that by myself like reading the interest was
there already but i didn't know how to get that information so i sat in
library and read like eight years old
and it has been there since this
uh it's like it can pure there a little bit
and i'm not like effective like today and this will always this gonna be a
huge fire for me so you more i get
more i want to give of it yeah but i think i think the responsibility
the key part of the responsibility is uh you know be scientific about it and
and uh you know to say what you know and what you don't know right i mean there's things that
we can't don't profess that you you know don't be as basically and
the first steps of knowing the astronomy in the human history
uh we have almost 500 years ago maybe less with galileo than copernico
and newton but and now
in this almost maybe 70 years uh the
a aero special uh uh no um
well this the special um race of the you know united states and
russia and the the land of the moon and uh
it goes exponentially it's exponentially er they they
acknowledge that every year is going
if you put it in a graphic it's going exponentially yes
the the information you know all you have to do you have
your phone that you want a few clicks to get that information
yeah and that's very it's very powerful and we are not
prepared for that and we are continuing and
our the next generation it will be more advanced
i don't know i i hope to see it in the next maybe
a hundred years but i don't know maybe not but uh
in this past 20 years the technology
changed a lot and
i i grew up with the cassettes the vh vhs movies yeah and now you have
streaming your online and you see everything you want
and all that uh do the science
is almost from the science yes and uh
everything that you have today in your home is for science
yes and we it built it's built on trust we trust stuff
yeah they they turn on a light switch you know of course the lights gonna come on you know
they don't know exactly it really comes on you know but but
the conditionary air the to acclimate your room
in science it's nitrogen a full and it will compress it and and
everything but it's only science uh i don't know what will happen in the
next 10 years yeah in this read
it's i think well in 10 years ago i remember
you know uh 10 years ago i saw a cell phones uh in a in a store a
little sir in the walmart and i remember when i we
have in that time the the phones that open with the tape headphones yes uh
and then start to come the phone when you touch the screen what was oh the new
you know a finally of 2009 or 2010
uh i remember the samsung dlg and everyone was oh you can touch the screen
and i it comes the the application and everything
and now yes i was i remember i was working at ericsson
when we built that the first ever smartphone it was ericsson 380
e yep yeah yeah yeah i was on that project as a project
administrator so i uh [Music] i can tell you a lot of that uh phone
right i was uh while pekka was doing that i was at nokia
and and i remember going to china and um and uh you might appreciate this uh
in the early 2000s in china uh it was they had the time they were
all bragging about the tiny tiny phones they always had the people would look
so you would look at you would look at these larger phones like the blackberry and stuff and you bring them over from
america and they'd look at you it's like they'd laugh at you it's like right and now
now now if they had these tiny ones right now now now they have these massive
screens and it's like you know all the uh xiaomi and huawei and you know they're
all these massive screen tablet things it's really funny to see that because of
the touchscreen technology it's it's incredible right i mean it's nanotechnology
and younger and younger people are learning how to use that technology my grandsons
at age two and three years old could navigate my my daughter's
iphone to find youtube and then to find their favorite cartoon
my nephew my nephew is in september we will be
a birth two years and uh every time they
take the the phone of my mother is her grandmother
and start to er to unblock and then start to
enter to take the numbers and everything and you know
ten years ago it was very oh like this a very yeah
and then there was there was there was a pivot point there was a pivot point when uh when uh the the technology
was not friendly uh it was not friendly at all you had to be trained on it and
you had to learn all the ways you know uh but and and then all of a sudden you have these tablets
and like you say i go to the airport and you see grandma you know using a tablet
and and and you see a kid you know two-year-old toddler using a tablet and i'm thinking wow you know now you have
this super advanced technology but yet it's built so that humans can use it
very easily right which which is which is a change it's a it's a big shift paradigm shift in the way it was
developing in the past uh cameron when we built that first
smartphone 380 ericsson there was a rumor
that something called bluetooth is on board
nobody at the ericsson didn't know exactly what that meant but it was some
kind of radio protocol and
then they one of the project leaders got an
issue for that that he has to look for that if we can implement it
already because it but that was on its stage for developing the bluetooth
but yeah when i heard about that first time where we were what what
like any any any uh like any uh
equipment could connect to each other yes then that was like uh like uh
uh like uh smithy cassingren at the
galileo time yeah oh yeah you know a couple of days
ago uh i i i was talking with a friend and i say the the word
if you rewind it here is
and that's what i use when i saw movies in the vhs movies
or in a cassette when i play music
the the word rewind now i think it doesn't here in argentina it
doesn't exist anymore they put it back and put it again no rewind
what we can do already today because almost every
uh young have this latest phone because
they have to have i think 12 and so on and they have that incredible
uh cameras on those oh yeah already oh yeah today
you have all of here yes yes but all you can you can take that young with you
at afternoon winter time at 5 00 pm
and show them what their phone can do only
to get it stable somewhere and take a 5-10 seconds exposure from something
like oreo nebula and show them this is what you can do only with your phone
yes and they would be wow that could be as part
of something big just to take them outside and let them use their phone to take the
first ever first light
you know even even the uh even the uh the constellation apps right i mean
uh this is a really funny one um i was looking at some mugs um that have
uh are the horoscope right the you know the astrology uh science
and it was like oh yeah what astrology sign are you okay i'm you know uh whatever and then and then i actually
use i i actually yeah whatever it was virgo i think and um and i i actually used the uh the
astronomy app to find out when the sun is actually in the constellation and guess what i discovered
scientifically and you guys know this this is a good fact for us all to know is the old the astrology that everyone
uses to date with cancer and all that that the 12 constellations actually is based on babylonian time
five thousand years ago and there was a shift there's a shift in the uh in the car where the sun is
uh it actually goes through ophiuchus exactly now yeah the third thing is actually another one and all of the
constellations are shifted by basically uh one so you know i we used to be pisces but
now i am uh the next one i uh yeah so i'm not pisces
anymore i forgot what it was and i thought i found that out by looking at
uh sky safari and then i did some research and it was
like so this is the cool part you know the science where the self-discovery and this is what you know what we're talking
about here is um is as you give the technology and you teach people
how to use it and how to learn for themselves yeah and they go through that astronomy
journey where like you say they take their own pictures or they do their own sky
search and and you know go sea of solar eclipse or whatever right or
and or comment or the as a comment or or a meteor shower
when they can have all that and they can self-teach it's it's it it it really makes a
difference i think for society and for people because for for them to be able to do
that themselves it makes us much healthier and uh and and and much more
connected to to the universe i have read that
astronomy from astrology because some some yeah
some uh a long time ago saw that there is uh actually
uh some uh kind of
upcoming events and the the astrology and astronomy uh went
apart some some for long long time ago
right here i have the the book that i wrote
my professor of physics
astronomy from the earth to the cosmos this is what the the book
and in the page 206
uh talks about what we are talking about right now the the cellular science
and here is a graphic uh
i don't know what it say it says the the constellation for example
and the the the period and the number of the
days that has that sign that constellation and here the names of yuko
and between scorpio and sagittarius and a fuco goes the 29th of november to
the 15th of december it's only
17 days so basically that changed a lot of the
uh the the the the point of view the astrology and
the the the people that do astrology they don't care about a they
they because because they they they don't match
the predictions that they do so that's why
uh well for science uh it comes down the
the prediction well well there's a lots of huge difference between the knowledge and the
believe it's your beliefs right yes
yeah but um yep that was really really nice
i think our viewers of uh many of them have already called it a night
i think so we we had to do this we with a beer
together i thought maybe in the future and
and do the the the pod a podcast live or live stream
yeah in a very huge table and talking about things astronomy and everything they
will be guys i can tell you that if the
the first side of a milky way will give me the same
emotions that i saw in my dream that i be i
i was taken to a hill that the one big tree
uh hide the sky and the first i saw there was magellan clouds
through through the tree and then i was moving beside the tree
and on the hill the whole milky way was like 40 degrees
wide and the whole sky and if the emotion was so powerful that
i woke up you mean you mean like what's behind matthew right now
it was uh like it was a dream but it was so powerful
the the emotion in my body it waked me up that's awesome
so now i have to see it now i just need to see it
you're real pecker you will
almost 3 a.m
so i have to continue in the office
that's it it's great to have these again good to have you back scott and um yeah
we missed we missed you and uh missed our our chats but we we made up for tonight and uh we're back on track so
this is this is awesome i hope you you enjoyed your holidays and yes and hope
hope this was the first and last week we have to be without definitely
girl yeah no it's good it's good yeah right
well guys thank you so much and uh the programming is going to be
different uh uh towards the end of the week um because we're doing the astronomical
league convention so that's an almost whole day broadcast it
actually starts at about three in the afternoon and goes until i don't know eleven at night something
like that so it's be really good they got a great lineup of speakers and uh so it'll be
something you'll want to watch um on uh tomorrow cameron we are going to
um uh we're going to be broadcasting a little bit early okay
so uh but uh we'll we'll get uh we'll get in touch with you about that
so yeah i can't kent already reached out to me i'm good yeah i think you're with your your windows from 1 to 3 30 max
right that was my time sorry sorry yeah it was
uh it was uh central time i think you were three to four thirty so three to four thirty is the window
for the show right no yeah i think i think we need a like in the nasa headquarters uh
the all the the clocks of the different sciences oh no that's the camera
that's
mine's on my phone here my iphone's got world dog i got this
oh there we go yeah see there you go different uh i think
there you go different countries i
the sidebar of the menu and i do the math oh it's called have two hours less oh but camera has more no
that's right by the way by the way guys uh swedish astronomers association which
i am a member of uh we will have a live
uh broadcast uh to our members on from las palmas la palma
observatory in grand canaria 25th of uh
august excellent week thanks
because of the koveed they have decided to make this big event for us in
sweden to uh from observatory from la palama it's
uh uh virtual so excellent
oh that's super cool okay see if i can record it somehow and show parts of it
on because it is i think it will be in english
okay all right let's see i can try to record and make it
short you know my wife when they have when she has to do
a study in class with some program she
use an addon in google chrome that records the the session and then
download it and what they she will see it again if if she has some
doubts or everything maybe in youtube if you search it it will help
you yeah but i have screens recorders ah so oh so i put on the
screen recorder and and if it's in swedish i can i have a text editor so i
can uh lay up put on that in the movie excellent
excellent yeah professional nice no i haven't tried them yet
remember i have them but i haven't used them yet pikachu
astronomer and producer [Laughter]
thank you so much thank you thank you scott and great show
it was good it's good to be back soon i think soon
those who are main uh participating in star party yeah they
they will want to be in the the the after party is there yes
all the fun happens here that's true that's right stop we have only us after party
