Global Star Party 81

Transcript:

6:00 p.m..Scott Roberts - Introduction
reproduct jupiter's moons and i presented it in class as one of
6:05 p.m..David Levy – Intro and Poetry
the things for talking about kind of the move from geocentric to heliocentric and my student asked me a question and i
answered him but i'm wondering how else i could have answered him so david he asked
how exactly seeing moons orbiting jupiter disproved
6:20 p.m..David Eicher - Minerals of Planet Earth
the geocentric theory why wouldn't the geocentric theory simply be adapted so that
multiple bodies could have their own systems but everything would still be
6:30 p.m..Astronomical League Door Prizes – Carroll Iorg
around earth primarily well and it didn't in exclusivity but it
6:35 p.m..Karim Jaffer
was the you know phases of venus um inferior phases of venus and and
6:45 p.m..Glenn K. Roberts
other evidence that that led to the whole the whole movement um in
support of copernican theory um so it independent of you know jupiter just looking like a miniature
solar system of course wasn't enough my point to the student was basically
7:00 p.m..Jason Guenzel - The Vast Reaches
that simply took away the specialness that they were claiming for earth the idea that only
7:10 p.m..Ten Minute Break
earth could have things revolve around it once you see it starts to open up the question of are we missing or are we
stretching our explanations too far to try to keep this model with all the epicycles and deference and everything
7:20 p.m..Navin Senthil Kumar
yeah yeah that's a good good answer yeah
that's that's great i i'm loving this part because the students i mean they they know
7:30 p.m..Adrian Bradley - Nightscapes
they basically know the heliocentric model they know a bit about this idea that planetal
planet orbits our ellipses but the impact of it and the way in which it came about when you go through
7:45 p.m..Nicolas Ariel Arias - Hammertime with Nico!
the history it really starts to shed some light on the way in which human nature works
and there's that critical moment that comes later you know tico was fooling around in various ways essentially but
8:00 p.m..Marcelo Souza
when it came to kepler and mathematics really joining there was a sort of a first brush stroke
toward you couldn't quite say astrophysics that early on but a mathematical
understanding of orbits and and how they worked onward to newton then
8:15 p.m..End
it always throws them this idea that tycho was actually a geocentrist and that he was sure that that's what the math would
eventually show he he partially bought into that but he was very skeptical of copernicus too in
a lot of ways yeah well i mean the numbers just weren't working it wasn't giving us any better
predictions and that was one of the one of the main uh critiques of the islamic scholars on
the yamaguest is that it just was not giving reliable predictions
and finally along came the redolphine tables and improve the accuracy of of things
you know i honestly just history of astronomy would be you know a multi-semester course if you had time to
do it oh yeah yeah and so detailed you have to have people
who are really interested in it though it a lot of these kind of interstices in
this era of the first or second millennium of since
you know the last couple millennia it that gets to be pretty thick stuff for a lot of
people unless they're really interested in history i find the ancient astronomy is something that
this term is capturing the students more than the indigenous astronomy so i've cut back a little on that compared to
last term where they really wanted to know all the indigenous stories last term i ended up doing an hour and a
half on just indigenous stories from across the world and connecting them to things you can actually see when you
look up this term it's a it's a different shift for the court and i like that i like the
fact that the students have different ways of approaching the material yeah and and different interests within the
yeah that's a good thing gives you some variety as the teacher too which is nice
oh it never stops [Laughter]
i have to say i love the part of the quote the nuclear waste from fuel that makes stars shine
for those that are cynicists at heart you know think of ourselves as nuclear waste just kind of
speaks volumes
scott have you had a chance to say bye to jupiter since it's uh leaving our evening skies i've been watching it move across
the sky for months you know so i just love you know to see the planets move
across the background of stars you know week after week and and uh
of course the the uh the great uh conjunction you know with um
with uh uh jupiter and saturn was just mind-blowing you know to see how really
fast it moves you know that was incredible when and i know uh
mars and venus are going to be in conjunction again in about a week and a half or so um and i think in two weeks they'll be
in conjunction with the moon again and it's just right now getting the students to
realize that things leaving the evening sky simply means they're moving to the morning they're still there
it's it's kind of this neat little effect where they're like oh wait yeah that's true and then some of them get up
early in the morning before sunrise because it's late enough right now that they can do that but in the summertime it's pretty much
just the evening skies that we concentrate on right
i love this visualization um you know i just uh
to be able to run these computer simulations of you know with a lot of
i guess you know the best observations in math that they can they can throw at it um
it's uh it's just incredible what they're they're showing us today in in
in this way we're spoiled
we are we're spoiled and can you imagine what this is going to look like 50 years from now you know
it'll be augmented reality you can actually move into a star system and change the scale so that you can see
everything move around you right i mean the technology is there now it's
just a question of figuring out which data to represent best and and then having somebody with the time and energy
to put it together but it's almost going to become automatic
processes just like it is now where often the data immediately renders images for you and simulations for you
because that's the way you write the script from the start
i mean part of the question though here is when you have people with visual disabilities
how do you get this level of intricacy across to them and
sonification would only wouldn't do it because it's it's too one-dimensional personification so you
need to have other ways to represent this hi carol
good evening david how you
doing good to see you carol good to see you again how you been
well we're doing all right but this pandemic doesn't seem to be ever wanting to end
i agree
but we're very glad that scott is doing well now yeah
that's scott's actually very happy about it too
i bet you are yeah it wasn't horrible it just was um
tiring for sure yeah it's exhausting
okay i'm gonna move along here
[Music]
ada karina is the most massive star within 10 000 light years
in the mid-19th century a tremendous eruption hurled enough gas into space to make at least 10 copies of the sun
creating an expanding nebula still visible today new results from nasa satellites ground-based telescopes and
theoretical models are providing astronomers with an improved understanding of the system
at the nebula's heart lie two giant stars the smaller of the two is 30 times the
mass of the sun and a million times brighter the primary weighs 90 cents and shines
five times brighter than its companion both stars produce powerful outflows
called stellar winds but the primaries is so dense that prevents astronomers from directly observing the star
the secondary's orbit is among the most eccentric known every five and a half years when the two
star is swinging toward closest approach or periastron they come about as close to each other as mars is from the sun
eta carina's most recent periastron occurred in august 2014 and many of nasa's space-based telescopes as well as
ground-based observatories looked on where the stellar winds collide temperatures reach hundreds of millions
of degrees hot enough to emit x-rays but the x-ray emission shuts down near
periastron when the smaller star is swallowed up by the dense wind of its larger companion
the x-rays gradually recover after periastron but they do so a bit differently each time suggesting
structural changes in the dueling winds recent observations have helped theorists refine computer models of this
interaction here darker colors indicate lower gas densities around the stars while the
stars themselves appear as black circles when the stars are far apart the winds collide head on creating a huge cavity
surrounded by 50 million degree gas but near periastron the secondary whips
around the larger star carving a tunnel through the primary's dense wind the secondary star's rapid motion
changes the collision zone from head to tail the smaller star's faster wind flows out
along the cavity it created and then crashes into the outward moving wind with its companion
from our perspective on earth the x-rays fade then recovers the stars move apart
new 3d models of these simulations reveal the formation of finger-like protrusions along the cavity near
periastron features never before identified theorists now investigating the
phenomenon suggest they may arise from instabilities developing in gas as it flows along the cavity wall
astronomers also keep an eye on eta carina with the hubble space telescope these images show a structure resembling
a crab formed by gas excited by the secondary star's intense uv light [Music]
this light dims near periastron when the secondary passes through the thickest part of the primary's wind the gas
relaxes settling into a lower energy state as a result the crab appears in a
different spectral line until the stars move apart and the uv light is restored [Music]
ada carina is one of the closest and most massive colliding wind binaries and serves as a natural laboratory for
studying these rare and important objects while its past eruptions remain
unexplained astronomers think they have a handle on its current state a claim to be tested at the next periastron in
february twenty twenty

uh

well hello everyone this is scott roberts from explore scientific and the explore alliance and welcome to the 81st
global star party i have been out for a while but it feels
so good to come back and be here with my friends and be here with all of you
to explore the universe together we have a great lineup of speakers
for you today and you know we are
waiting to interact with you on live chat and
we have uh uh you know we have uh david levy up next david eiker uh
kareem jaffer uh carol org uh jason gonzale and my many
more will be on tonight so um but we will get started um
earlier uh david was
regaling us with a song about vincent van gaal and
uh it was uh you know a beautiful song by don mclean i i wish that we could have played it
uh for this particular global star party but uh uh you know we are kind of prohibited
from doing such things uh because of copyright issues but uh it really had helped set the mood
uh for the event and uh you know that's one of the things that
david always does is he helps set the tempo and the mood for
i think every event he goes to uh we're blessed to have him attend all of our
global star parties and uh you know very thankful to call him a friend too
so david i'm going to turn it over to you man thanks for coming on to uh our 81st
global star party thank you scott and welcome back i think all of us will
can say that we are we missed you a lot we're glad that your um
about with covent has not been that serious and that you are recovering well
and it's good to have you back our star party tonight dealt with a very important star
at ocarina and i wanted to begin by saying that
my friend bart bach who was a very famous milky way astronomer
his favorite star was definitely etta karina and at the opening of the flandero
planetarium in 19 november 1975 um he was
he arrived early with his wife who was quite ill at the time with alzheimer's disease
and they went to the back room of the planetarium and priscilla stopped and she said edda
karina and bart said yeah what about it and she said that's where i want to be
i'm going to be after i'm gone from here i'm going to be at edda carina
that's where the good lord is making his cooking stars faster than anywhere else in the galaxy and that's where i want to
be four days later priscilla
had a heart attack and passed away and i think we all like to remember now
that both she and her husband bart are now watching over us from the atacarina
nebula i wanted to talk today about a different sort of artwork
not poetry not prose but art itself uh some of us were able to hear
on the zoom session uh don mclean's very very famous song
starry starry night actually it's called vincent but you know how it all begins starry
starry night and goes on and talks about how vincent van gogh
had this really sad depressive life and when all hope was gone
he took his life as lovers often do and the line that comes after that i've never forgotten it's just precious
the world was never meant for some for one as beautiful as you
and we can't play the song to you but we can i can read a little letter
that um a van gogh wrote to his friend bernard
said that same week a starry sky he wrote to bernard a starry sky is something i should like
to try to do just as in the daytime i'm going to try to paint a green meadow spangled with
dandelions he compared the stars to dots on the map
excuse me and let's try again to dots on the map and the news that is one takes a train
to travel on earth we take death to reach a star although at this point in his life van
gogh is disillusioned by religion he appears not to his lust his belief in
an afterlife he voiced this ambivalence in the letter to his brother theo after having painted
starry night confessing to a tremendous need for shall i say the word for religion
so i go outside and i paint the stars back to you spotty and thank you
thank you very much thank you um we uh um
yeah i love looking at uh vincent van gogh's paintings especially
uh you know i seem to me to be one of the few painters who who love love to paint the night sky you know uh
and uh it's so lively and interesting you know that uh i think his own his own
thoughts about the universe was that it must have been you know utterly alive everywhere where
he was he could see so um but uh
uh you know and and the and the starry starry night painting is just one of them there are many uh paintings that he
did with uh with the starry sky so okay well thank you very much david uh
we are going to um we are going to uh switch to uh
another david david eicher uh the editor-in-chief of astronomy magazine another dear friend uh
someone that uh uh you know that i i
with david levy i get lots of uh energy from you know when when we get into our
conversations about uh uh things that are happening things that we could do um you know uh in astronomy
i i'm just uh very very grateful to have friends like i have here and uh
um you know it uh it makes it makes my experience in astronomy
uh you know i 100 fold over what it would normally be i believe so
mr eiker thank you so much and i am going to turn this over to you man
and likewise scott and we're all very happy that you're feeling much much better it's good to have you man
thanks and i will see if i can share my screen
i'm going to talk about a little more planetary geology i haven't run out of
minerals yet and i will start uh the slideshow and can you see a big tanzanite crystal
yes okay well i will carry on earth's universe of minerals this is of course
how the universe likes to make planets by assembling atoms in
minerals and it's a universe of order thomas jefferson said i believe in a divinely ordered universe
isaac newton uh even earlier said truth is ever to be found in the simplicity and not in the
multiplicity and confusion of things and now uh
several centuries after each of them we know that the universe is ordered not by a supernatural design but by the
principles of physics minerals are nice in that they show how planets are formed they we know through
spectroscopy that the chemistry in the universe is uniform throughout
and we have different local conditions temperatures and pressures and so on but we know of the same atoms that are
assembled in certain ways not by accident but because of their properties and we can hold minerals here on earth
and imagine that lots of planets out in the galaxy and other in other galaxies are very much like have minerals very
much like the ones that we have as well minerals demonstrate that order their
atoms are assembled in precise ways by electrochemical attractions not by an
accident or randomness inherent properties of the atoms that make them up and guide them into assembling
in a specific what mineralogists call a crystal lattice when the atoms of the right type are
together and and so on so tonight i thought i would talk about
a couple that are fairly popular among human beings gold and
silver they're both we know now over the last decade or generation a lot more about
the origins of the elements gold and silver among other precious
metals are some of the elements that are created in colliding neutron stars
now so when we uh hold a piece of gold or silver or jewelry that we like
in our civilization a lot of it's gold and silver were holding atoms
that were created in neutron star collisional deaths if you will
gold of course uh the symbol a you it was one of the first metals used by prehistoric cultures it's the color is
termed gold of all things and very slightly with slight uh differences in the alloys of little impurities of other
atoms that are in with the gold the old english word gold dates to about 725 a.d it may have been derived from
the anglo-saxon word gold the latin name was aurum
thus the abbreviation a you it's a member of the copper group of
minerals mineralogists term it and it uh it's gold is very valuable to us and we
we treasure it and it's not corruptable it doesn't oxidize it's very stable over long periods it's not terribly super
hard compared to some metals but it's very stable um it uh
if we could extract the uh dissolved gold uh for example that is
in seawater uh on earth gold would be completely worthless
but there's a catch we can't so it's something that's hard to find in a metallic form and that's one of the
reasons why we treasure it it occurs in hydrothermal quartz veins in volcanic
sulfide deposits and in unconsolidated placer deposits the way it's easy for us
to get gold although it takes a lot of searching as culture has shown us the
crystal structure of gold is like some of the other minerals we've looked at recently it's isometric which is a fancy
word for cubic and here's a crystal lattice diagram of gold
and then one of its friends silver and other precious metal uh the native element its symbol is ag
it's used for many many many things these were two of the earliest metals that were worked uh by humans on earth
it's used in everything from tableware to jewelry to coins scientific processes photographic processes
its color is silver black and unlike gold silver is very prone to oxidation
so it oxidizes to dark gray or black the old english word silver was the origin
the current silver dates to about the year 1478 and the abbreviation ag
derives from another latin term for the substance argentum
it's also a member of the copper group and it also occurs primarily in hydrothermal veins and so it sends
those who are seeking their fortune as we can read about in the old west in the united states or many other places in
human history on uh scurrying hunts for valuable veins throughout the
quartz and other rock crystal structure of silver is also
isometric so it has essentially the same crystallography as gold air variations
of course here but this is the basic for both and i thought i would just show a few examples of some pieces
from my collection gold and silver is very easy to find mostly
at something that is going on right now and for the next few weeks in tucson arizona near where david is the tucson
gem and mineral show which is uh along with one that's held in munich the
biggest show on earth for collectors it's hard to get into these places as it
wasn't 100 or 200 years ago and find specimens of this stuff now uh lawyers are worried about people
falling down mine shafts and never being heard of again and so these are all sort of off access uh the
minds now you've abandoned minds and and so you need to go hunting for these things at gem and mineral shows
so tucson right now if you're in that area that's the place to be this is a nice crystallized gold on quartz you can
see that this is how it crystallizes in a vein of courts from placer county california that old
motherlode area in california here is a crystallized sheet of leaf
gold and you can see if you look very closely i didn't take microscopic photographs of this
this is a piece that's about uh four centimeters high or so but you can see there are tiny little uh
tri trigons they're little little uh triangular crystal
octahedrons and other shapes of the gold how it crystallized there almost like a
feather this is from a very famous mine called the round mountain mine in nevada
this is an old piece from my father's collection from many years ago from the 20s or 30s from a very famous mine the
homestake mine in lead south dakota does anyone know why the homestake mine is
very special not just to mineralogists but to astronomers
no no no well now there's an for many years now since it's a defunct gold mine there
has been a neutrino detector in the homestake mine so it's they've thrown it over to the
cosmologists now from from the mineralogists interesting
here's another piece that i got from a colorado dealer of minerals this is a very famous mine that can't bird mine a
very famous gold and silver and other uh um minerals from yuri colorado and
this was a piece that was cut and held onto and found in a miner's bag
that was discarded and you can see little bits of gold here well the miners were always trying to make off with
so-called high-grade pieces that they hid in their bags and their boots and so on sometimes it worked
this is a piece of now calivorite is a gold mineral but it's a gold telluride
it's made up of gold and tellurium and that's uh one way that you can find a lot of gold in
the colorado deposits of gold as a gold telluride my father being a chemist and
he found this piece out in creek a very famous mining district in the 1930s
and he took one he cut this piece in half as you can see and and the original
untreated pieces on the left and you can see on the right side he roasted that piece and that bubbles out the gold you
can see some little bubbles of gold in that piece that uh that the heating created
to make more visible in a gold telluride
here's from another very famous colorado mine a little piece on quartz the little johnny mine in leadville colorado one of
the most famous and storied old gold and silver mining towns uh up in the
the them are hills west and very much higher up than denver
here's a very nice piece of sort of spongy gold this is a large piece it's about the size of a football with this
spongy gold from the oling house district in nevada this is a more recent find of
gold and you say it's spongy i mean if you were to touch it is it
uh i it is a spongy field you have to be now now pieces like this
and and uh and [Music] these guys are are pretty durable
yeah you know gold is a reasonably soft metal compared to this is quite fragile though this piece
here that is they're almost like little spongy needles uh covering a fairly
large piece so this you have to be very very careful with you wouldn't want to shove your fist into this or you would
lose a fair amount of its value interesting
now we go on to just some little examples of silver native silver this is a the so-called wire silver this almost
looks like a little boot this piece here and it has a silver mineral called a camphite that's a
silver sulfide mineral and some white calcite and so on too there's a lot of
silver in a region that has come out relatively recently in the last generation in morocco this area
and you can see this way that this uh silver crystals grow in in a wire
uh crystal habit here often here's a mexican
piece of silver and this is this sort of herringbone crystal habit now the
crystals are growing up cubically but they're growing out and and losing uh
running out of material to make more cubic crystals on a very small scale and
so it can create this sort of fishbone look that again has some calcite with the silver there
here's a wire silver example holder piece that is from a very famous miami
district called freiburg in saxony in germany this is one of the oldest the oldest examples of silver
that exist as mineral specimens are from frank the fryeburg district here this is
the oldest silver mining region on the planet this is a this is going back to morocco
now and this is a big piece that is about a foot and a half high and you can see that there's a piece of country rock
on the bottom there and then this kind of big hand of flat piece of silver
is sticking up off of the country rock here is embedded in the rock and that's a
a big piece uh larger than a couple of hands of this very thin
uh uh um uh crystal uh crystallization of a flat sheet of
silver this is from a famous canadian silver the cobalt district of mining silver and
other metals minerals metals in in ontario and this is a piece where
there's massive native silver in this piece you can see the silver pieces with a little bit of other
impurities of stuff in there that's darker colored and this is a piece that's actually sawn
to to reveal the silver in a solid block here of of nearly all silver
then this is a silver popular silver mineral you can see the nice little crystal shapes in this this is a
camphight which is silver sulfide again from that moroccan area just
showing you some different forms here back to mexico a famous area called the
zacatecas mexico has a lot of silver minerals and this is pyramid
which is a silver antimony sulfide and you can see the unusual crystal habit
there and here is silver you wouldn't want to grind this up and have it at your dining
table this piece this is native silver crystals very very fragile wire-like uh
uh crystals growing over this country rock which is arsenic native
arsenal so you have to be careful handling some of this but in saxony germany a silver occurs
intermixed with native arsenic often as well wow
and that's it those are some examples of gold and silver just to show you that kind of range of what samples and
specimens look like and again i will shamefully mention that michael bakker and i are coming out with a kid's book
about space exploration still months off in the fall but it's ready to
go so thank you back to you scott thanks for having me again i will stop the
screen sharing and throw it back to the head man and we're glad to have him back this week
yes we are but uh david i didn't see the uh gold chain
that uh rappers use i was looking forward that herringbone though so i found that he to
interesting now if you you're embarrassing me because now i almost feel like i have to mention this it's
not it's it's it's a meteorite bracelet but but i have a special friend who's a
rock and roll guitarist who sent me a very fancy meteorite bracelet now maybe
next week i'll have to bring that on yeah you have to wear it yeah looking forward to it
i have to say the physicist in me was really happy to see the crystalline structure comments about gold and silver
because that's why those were the two that were considered for the james webb space telescope because
that crystalline structure gives you enough free electrons to be really reflective to infrared waves and so
it's great to see that they have that such a commonality in structure and john mather would say shame on you
but can we just have a moment of silence of relief that the webb telescope deployed in the
most complex way ever successfully wow john it's amazing no problem it's going
to happen just like that the whole the last five years he said that and he was right
this is a uh gibeon meteorite that i have i've shown you before
yeah and it is my wedding ring i just wanted to want to show that to
you david pull it back maybe just a smidge far away from the in there maybe it's in
a little bit better focus there we go yeah yeah yeah yeah excellent yep i can see it
and that's what i've been doing before
so it cuts very well to make stuff out of but it shows that you you beat me too
it's got that vietnam pattern of crisscross pattern and that only occurs
in iron nickel that has taken a couple of hundred thousand years to cool which
creates that strange crystallization pattern the vietman shot and pattern
that does not happen with native iron on earth at all so that's very interesting signature
meteoritic puts my uh rubber uh active wedding ring to shame
i need to uh i guess i gotta wait a couple hours so i can have one like that
mine's not made of crystal unfortunately david before i let you go um i just uh
wanted to touch on uh astronomy magazine as well um and and
what's what's coming up with uh uh you know what's in the current issue at this time we go we oh gosh i'm
thinking about issues at the end of 2022 now that i'm planning um we we have a
big story that's that's just about out from from this pocket guy planning for the 2024 eclipse
you know which is only two years away now that's going to be the most viewed eclipse in history
unless god forbid we shouldn't even say that it would be clouded out the whole us you know but there will be a hundred
and fifteen million people in the path of totality could be more people than the 2017 eclipse that's right
because it goes from mexico through texas through the ohio valley and up the eastern seaboard so many more popular
many more cities are in the path so that's very exciting and not too early to start planning for the eclipse two
years from now we've started planning already in quebec as well i mean we've got it passing straight through the city
here in montreal and uh straight into my megantic even our dark sky area so we
we've had a committee of all the local institutions the schools everybody who's involved in outreach
getting together to plan out a whole strategy because this is the right time to get people to look up is because there's
something big coming and like you said knock on wood about weather but even if it's not here we'll be able to share
views from all across absolutely yeah let's hope
keep going david go ahead well not only good weather but let's hope that um
the social and actual all parts of the pandemic by 2024 i
think it's projected that we would be beyond all of it we'd be back to readjusting to a normal life and
what better way to kick it off by getting people together to witness a total solar eclipse
yeah well here in the states we're definitely we're trying to push it a little bit further forward
today was the first day back in the office for me so you know that's that's the united states
i know different countries are carefully moving forward in their own ways to uh
you know navigate where we are right now at the pandemic so uh yeah with that note i'll go back on mute so we can go
back to talking science and astronomy well we've got a lot of science coming
up in in astronomy as well and the cat is kind of out of the bag on this so i could mention this
a few issues from now we're going to have a very special issue that's never been done in any
publication that will be an entire space art the state of the art of space art
issue years ago astronomy was very much noted for space art you know the imagery
that we have is a lot better than it used to be in the 1970s now but still space art can take you to places
as steve walther the magazine's founder used to say man's dreams of worlds unseen can take you up close to a
neutron star collision or to floating strange things in the
atmosphere of a gas giant planet or wherever so we're going to have a space art extravaganza coming up that's in
conjunction with the iaa the the association of astronomical artists um
and that will be very very special coming down the pike that's great well i want to
um i want to mention that uh space artist michael carroll sent me a
number of books um this one is drifting on alien wins he did a number of books on with uh
springer as a publisher and each one of the books that he sent to me he uh he made a very you know he signed
them and put some nice little illustrations and then there's that one um
you know so i'm gonna have to dig into these books and and check them out here's uh here's another one where you can see you
know nice illustration this is lords of the ice moons you know scientific novel
um plata plato's labyrinth as another one all
these illustrations are done by michael carroll and uh so dinosaurs ancient greeks and time
travelers what more do you want you he's know long time friend he's a great guy he's
one of the great artists uh in the world of space art and has been for decades right he's a
long time astronomy author he has a story coming up as well down the pike about eyeball planets
in astronomy which are these two planets that have completely different sides because
they're tidally locked so there's a lot there's a mike carroll story coming on about down the pike about that as well
but uh some of these illustrations i mean that's that is classic michael carroll uh illustrations right there so
so realistic uh yet seen from perspectives that uh
that we'll probably never actually get to to experience ourselves so you know uh it's it's very very cool
and well i wanted to give him a shout out on that and you gave the perfect segment play for that so thank you david
that was great so um thanks and the the specimens that
you showed today were beautiful i think everybody was like salivating especially over those gold uh specimens
so well thank you and you know the we have one real problem talking about all these things we love to talk about
going back to douglas adams space is big really really big really really really
we'll we'll always need astronomical art to show us those places that we're never going to see up close
and that's kind of a good thing that we have that then that's true well great thank you so much thank you
thanks scott all right so up next uh we will go to the astronomical league
the astronomical league does the global star party door prizes and they do that
with a series of questions that that are generally multiple choice and
uh carol orange the president of the astronomical league will uh
is here with us today um he uh you know he has been with the league for
i think over 20 years uh something in that range maybe even longer than that uh you know
lost count that's right and um you know the league is largely made up of
volunteers you know that there's not uh you know there's no big salaries there's
um but they're they're they're big in their commitment to amateur astronomers
they're big in their commitment to uh education and astronomy and uh with a
federation of over 300 clubs and over 20 000 members they're one of the biggest things going on in the world of amateur
astronomy today so and i got to see uh carol live in person
uh here in northwest arkansas a few weeks ago maybe a couple of months ago and uh so it was that was very nice
and uh let's get out and person see some of our fellow astronomers yeah that's right that's right so it was
great to watch uh carol hand out some uh amazing astronomical league awards so
i'm going to turn it over to you carol thank you scott great to be here after a couple weeks off and
glad to hear you're doing so much better scott a lot of exciting things we've been discussing tonight a lot of things
coming up in the next few months and so that's always good there's always something to look forward to in astronomy
and i'm going to share my screen and give away some door prizes or at least
look at some answers
okay
my window out the way here we go everyone see it
yep perfect here's a warning we like to put out uh in the first screen
uh if anyone wins a door prize that's a an eyepiece an optic uh we want to make
sure that they're using the proper precautions as far as not looking through instruments uh without some
filtering if you're looking through a telescope toward the sun so
two weeks ago we had the january 11th gsp and we had some questions from that
one here are the answers number one this 72 inch telescope held
the record as the largest in the world for 72 years until the 100 inch at mount wilson went
into operation 1917. and what country is this 72-inch telescope located
and the answer is lord rosse levithan of parson town is in beer
that's b-i-r-r ireland okay that was answer number one
number two this is the second largest moon in the solar system is it
earth's moon ganymede titan or sharon and the answer is c titan
then we go to number three this galaxy
and that's gn z11 inertia major this galaxy is a
record holder what record does it hold is the furthest known galaxy largest
known galaxy furthest companion of the milky way galaxy
the fastest rotating galaxy or host to largest black hole the answer is
furthest known galaxy okay
and from that january 11th session we had several names some very familiar names
that are on here quite often cameron gillis adrian bradley google mayor taliga
rich creland josh kovac rich eubank mike
overarcher john keogh uh and let's see
hendrick ortega and uh
melody yeah there we go i am kelly latuno okay
and then
the winners for january 2022 are rich krillin
andrew corkill and kelly let her know
great all right and then the questions for tonight and send your
answers to the questions just as soon as you can to astro league
secretary astrolage.org
question number one who was the founder of the greenwich observatory in england
who was the founder of the greenwich observatory in england
question number two which planet in our solar system
has a year that lasts 84 earth years which planet lasts
84 earth years for their years
number three what is the fastest rotating planet in our solar system
the fastest one as far as rotation and again send the answers to secretary
astro league.org
and a few weeks from now on friday february 18th we'll have the next astronomical
league live for uh the month and leading that will be john goss a
past president of the astronomical league and he's got a fascinating title all is change amateur astronomy from
impressionism through post modernism sounds like a fascinating topic and you
want to tune in for that we hope to see a lot of you there the main gang will be here from the
league as well as scott david and molly uh one of our imagers
and then coming up we've got some other things involving whoops
uh the 2022 alkyne right that's coming up
and we've checked with the local folks in albuquerque everything looks good as far as the state
they are gradually relaxing their requirements in new mexico so we're
confident that it's going to happen year three we've been trying to do this and it looks like this is going to be the
magic year they've been very patient they've hung with us so we're looking for it uh to see what uh uh
a great uh feeling it is again to have a group of astronomers together in person
zoom is wonderful uh the media in various forms but it's not quite like
getting together so that's coming up next scott back to you and i'll put sharing
my screen here all right and
here we go can i help you out with that thank you yep uh we
uh i i do want to add that um uh and i did put the link in uh
in the chat there where you can go and join the astronomical league you can join the astronomical league through
a club that is uh known as an astronomical league club
there's you know there's over 300 of them in the united states but you can if you live uh outside the
united states you can join as a member at large um and so that is something that you can be
uh you know you can get involved with they have amazing uh observing programs
amazing awards programs uh and if you've never been to an alcon event you
definitely need to go because the uh their keynote speakers are usually uh of mind-blowing quality and
uh it's always fun to go there to meet up with friends and to uh be there with
your peers one of the special trips is going to be a trip to the great array there the larger rate yeah uh on the sunday
following the convention oh the vla yeah that's a that's a very uh special trip that complaints that's that's awesome
that's awesome well great well carol thanks for uh joining us today and uh we will see
uh do you already know who's coming up next week for um i don't remember let's see that will
be john goss john goss okay all right wonderful okay carol thanks again take
care okay so um let's see we are moving on to
uh the uh the montreal center uh royal astronomical uh society of canada and
with uh professor kareem jaffar and uh
we are uh you know uh kareem is uh
a great uh professor of astronomy and uh an amazing outreach ambassador and so
uh the rasc is uh is very fortunate to have him uh be part
of that so let's see you s you've started sharing before i could switch over to you let's
see let me get out of here sorry scott should i stop to start again
no no you're good you're good now awesome thank you very much thanks for the introduction and welcome back as
everybody's been saying it's great to be back at the gsps but it's more important to see you online again it's been it's
been wonderful to see you just pick up where you left off i see you online all the time on facebook and on youtube and
on explore scientific.com live and uh today's topic we've got forged in stars
and i decided to take a slightly different tangent to it and when you have something forged in stars you tend
to end up with stellar forges as well and so i'm gonna get us towards looking
up at stellar forges over the next few minutes but before i do i wanted to just touch on a couple of quick things and
the first thing that i did want to touch on is the james webb space telescope which both
david eicher and i mentioned earlier it has reached its orbit in l2 it's halo orbit and it's successfully reached it
they've also talked about the first target that they're going to be using for calibration which is up in ursa major and so i was happy to share that
with my class today and talk a little bit about the whole calibration procedure but the one thing that i did
want to mention that's not quite as happy or lucky is today is the 90th
anniversary of the columbia disaster and it's the third of our space exploration
unfortunate uh tragedies that we had apollo 1 the challenger and then the
colombia on reentry and it really is kind of a sobering moment to remember that uh you know with
exploration there are risks involved and so as we start to look back to return to the moon
that's something that we do want to keep in mind is that we are putting lives on the line every time we take off in a
rocket whether it's dragon or whether it's soyuz to go up into earth atmosphere or go further
we are very much uh counting on these astronauts to take those risks for us
and we all waited with baited breath for the last month as james webb made its
way out there in a whole automated sequence but we felt the risk all of us no matter
whether we were scientists involved in the mission whether we were amateur astronomers just enjoying trying to
capture a little glimpse of james webb passing through the night sky we were aware of the risk of what would
happen if it didn't quite deploy properly or if it didn't get there we've talked about it at the star parties over
the last month and a half but it's amazing how we all get to share
that journey we get to share that experience a lot of that has to do with outreach so i do want to do a brief check in with
some of our outreach partners and i want to mention that astro radio and especially the reach out and touch space
panel that i'm on is still recording every monday it's 8 p.m to 10 p.m british time which is starting at 2 p.m
central time and i'm so happy to say that on monday february 7 our guest is
none other than our own scott roberts so we'll be chatting with scott about all the amazing work that he does and the
panel is just looking forward to to hosting him and having a nice conversation about just outreach overall
but also our own individual journeys into astronomy uh at the rac montreal center we just
had a fantastic event a couple weeks a week and a half ago on celebrating the 30th anniversary of
dr bondar's mission into space aboard the discovery our next event is coming up in just over two weeks it's going to
be celebrating the first year of mars on mars of the perseverance rover and the
ingenuity uh helicopter so we have one of the scientists who's actually a phd
candidate at mcgill university erin gibbons she's part of the rover operation team and she helps to operate
the supercam science laser that does the actual chemical analysis of rocks so
she's going to share with us a lot of what she just uh learned so far over the first year and what's next for percy and
uh anybody's welcome to join bit dot lee slash percy one year and uh you can register for this zoom webinar
i'm also very happy to report that uh the junior astro league that uh david
levy has talked about a few times is now up and running it's an initiative of the denver astronomical society and our rac
montreal center has been helping them get up and get going and our first event is coming up on sunday february 13th
for youth ages 10 to 17. if you're a kid aged 10 to 17 or if you
know kids age 10 to 17 they do not have to be members of the denver society of
the montreal society or even of the astronomical league they can join us from anywhere in the world it's from two
to four pm mountain time on a sunday and it's going to be led by my daughter tara and she's going to be talking a little
bit about extremophiles and what we believe alien life might look like and then of course how to sketch it and that
art component that david talked about that really captures the imagination and allows us to look at what we wonder and
what we imagine things will look like when we eventually get there to observe that's something that's amazing in kids
and so we really want to see the kids creations and we hope to share them with you at a lo at a future global star
party as well i also want to mention it's the chinese lunar new year right it's 2022 it's
chinese lunar new year it's the year of the tiger which is the third in the chinese zodiac and it's based on that
famous legend of the race of 12 animals and the tiger ends up third and it's a
fantastic story and i highly encourage you to read that tale of competition
amongst these different animals and how the rat managed to win i just love that but the other thing to note that this
idea of a lunar new year and a luna solar calendar is not something that's particular to asian cultures there's
many different cultures across the world that celebrate a luna solar type of calendar and in fact even in the
aboriginals the hobie celebration in british columbia is based on the first
appearance of the crescent moon in february because that first crescent moon that's going to come up tomorrow
night it has this look of like a scoop the waxing crescent that's very very
thin and they actually refer to it as the celestial scoop so this tradition of a lunar new year
based on the lunar cycle and fitting 12 or 13 lunar months and having the
calendar shift accordingly is something that's shared by many different cultures both
cultures from across the seas as well as indigenous cultures right here in north america
it's also the start of the next lunar month and so this is the snow blinding or the snow hunger month and depending
on whether you're looking at it from the mikma or from the uh algonquin perspective and i can't pronounce the
name very well apoknite but you can always look at the mikma moons videos on
youtube the tradition is basically this is the hunger month it's the month where the spirit of winter is the hardest it's the
hardest for gathering for surviving for finding food and so to appease the
spirit of winter there's typically these celebrations done on the first night to
invite safe passage into spring and we also see this manifest in of course groundhog's day in uh here in
north america and we'll be celebrating that tomorrow and hoping that punxsutawney phil and wyatt and willie
get to see their shadow or don't see their shadow in this case because we really want an early spring
mentioning all of this i have to kind of harken back to the constellations that we look at when we look up in the night
sky and we've talked previously about the winter hexagon because that's really the thing that we look at most
prominently in the winter time we have this beautiful picture by adrian that he shared with us all the way back in the
fall of the winter hexagon or the football if you want to call it that with the super
bowl coming up and you can clearly see the beauty of the orion belt the nebula
there beetlejuice and rigel you've got sirius you've got procyon you've got the gemini twins you've got capella you've
got alderbrand you can even see the person the the proceeds there beautifully in this picture and i share
this with my students to give them an idea of why dark skies are so so important
and if you go outside of the city of montreal and you go into rural quebec you can sometimes get some beautiful
night sky views and this view here was taken by one of our local montreal astronomers francois canel and he was
happy enough to share this with my students and allow me to share this on his behalf for the outreach tonight
and it's just wonderful to see what you can capture with wide field photography
and so what i have my students do at this time of the year is i have them go out and do a globe at night activity and
the global night activity right now is to try to see orion and figure out how
many stars you can view and if you have reasonably okay suburban
skies you can try to capture a little bit of the constellation but if you're in the heart of the city you can see
those brightest stars and you can see the hyades but you can't see the shape of orion so it's really hard to know
what you're seeing but if you do manage to get into slightly better skies like what i have here in the suburbs in in beaconsfield
quebec you get to see the belt you get to see all four of the core stars
surrounding orion and you can see several other stars in that region
and then if you're able to get to dark enough skies off island all of a sudden the number of stars start to pop and
it's really hard in some cases to figure out which ones are the orion constellation because there's just so
many stars out there and so the globe at night website encourages during
week and a half periods every month to look at specific constellations and try
to identify how bad the light pollution is or how good the light pollution might look the lack of light pollution might
be in your specific area and so i have my students go and do that unfortunately
we have had nothing but cold and on the few days like this coming wednesday and thursday when there's not
minus double digits in celsius at night it's snow and wet snow and clouds so
i've managed to extend it by a month because in the end of february start of march they're repeating the orion nebula
one more or the orion constellation one more time but i had a couple of students go out and do the imaging nonetheless uh
chloe got this beautiful picture in suburban skies using her iphone 11 in night mode and she was really happy to
see that not only did she get the orion constellation really nicely framed by the trees but if you zoom in you can
either you can actually see just a touch of the nebulosity around the orion nebula itself in the sword
uh michael and two friends zachary and tristan they had gone out before the semester even started and they've
managed to get into darker skies outside of the montreal area and so they had taken a picture of orion just because it
was a beautiful night so they wanted to take a picture and even with the wispy clouds you can still see so many more
stars when you get out of the city into the urban areas and i'm happy to say that tomorrow in lab they're also going
to get to work with rgb filter data from our remote telescope to try to put together their own picture of the orion
nebula such as maximum and alex did this past fall here that i'm sharing with you
so when we're talking about forged in stars when you have stars explode they leave you in a nebula those
can create these beautiful new birthing areas for new stars and the orion nebula
is one of the most studied ones for us and so that's where i take my students early on in the term
so that's what i wanted to share with you today a little bit on a check-in as well as a little bit of what the
students get to do over the next little bit scott back to you thank you very much uh before i let you go um
uh you know i would like to uh also have you talk a little bit about
the rasc and how you can get involved yeah so the rasc has 29 centers across
the country pretty much every major city in canada and several of the smaller cities that have academic institutions
or just have a very large gathering they have rasc centers so you can look those up on
rasc.ca you can also just join as a national member but our montreal center actually
has international members as well chuck allen's a member pete williamson is a member adrian is a member over in sarnia across
the border from him it's really a society of not just
passionate astronomers but also hobbyists and educators and outreach specialists scientists
astrophotographers pretty much everybody from across the spectrum of
the hobby of astronomy has a place at the rasc these days a lot of what we're doing is
by zoom just like it is for most of the centers across the world but what we've been able to do is we've been able to
really harness this with zoom activities that bring centers together so our wednesday clubhouses we will we will
often have a member from ottawa somebody from london somebody from the east coast somebody from the west coast join in
into our conversation to talk about what we see in the night sky and so locally we're over 170 members across the
country we're at about 5 000 members in 29 centers very impressive yes and how how old is
the royal astronomical society we're about twice the age of the astronomical league we're 150 years old
nationally it started as a club in toronto uh back in the late 1800s and uh
our montreal center actually is now 104 years old uh so you know we're showing the grey a little bit
we have a dark sky area that is actually a member's farm that she lets us set up at
uh we also have an observatory in the darkest skies that we have on the island which is morgan arboretum run by mcgill
university and then we have an astronomical library at my college john abbott college
wonderful great all right well thank you so much karine that's great scott all right so so up next is um glen k
roberts uh glenn i don't know if we're cousins uh or or
some sort of relation but uh glenn uh if i'm correct you are also um
uh a uh member of the royal astronomical society of canada is that correct
yes that's true yeah right just before we get on further uh karim i used to live in uh bay durfee
quebec oh excellent yeah that's just between where i am in my college and actually we just did a
gemini uh geminids uh event with them in december and we're going to be doing a lyrics event with them hopefully in
april is that uh mcdonald college saint and bellevue yep that's that's so part of
part of our campus is mcdonald college and part of our campus is john abbott college okay right so when you're in the neighborhood
come on by absolutely and glenn you also write a
column uh an astronomical column is that correct as well
yeah i'm a syndicated columnist here in atlanta canada uh i've been writing gosh
25 years or so i write a weekly column so 52
columns a year uh wow various astronomy topics and uh
they're published uh in the the maritime newspapers and they're online and and
that and i do interviews with radio hosts and different shows across
canada i've done them in montreal i've done them in bc and whatever so
if you get a chance to visit the maritimes the skies there are incredible it's well you should i have a um
i'm an avid fly salmon fly fisherman uh and i have a place up in cape breton
nova scotia of marguerite forks and the skies up there are just to die for
there's no light pollution it's like you could reach up and grab the sky that's
where i take my 12-inch mead sct and boy do i ever get into a bunch of
deep sky objects up there so yeah you're talking about uh you know seeing the
nice guy outside of the urban area well you need to go to cape breton to the top
of one of the the high hills there if you want to see a clear sky i i suppose
it's comparable to arizona or mona loa or whatever but it it's just
magnificent so wonderful yeah so i i yeah i write those articles
every week and uh you know they're fairly good the response i get a lot i have a couple hundred people i send the
articles to directly people who have written me and asked me different questions or you know
queried about something that i've written and whatever so it's it's it's a bit challenging at times because i
sometimes forget if i've written about that over the last 25 years so right
but i was trying to put up i put a new twist on it and i try and keep it at a fairly
non-technical level i mean you get into a little bit of it like this week's article
was about kepler's uh first law of planetary motion and the one that i'm sending for next week is on
his second law it's a little technical a little called mathematical and that so
some people won't get it but you know i tried diversifying it so sure sure what what do you find the your
greatest satisfaction to write i mean what aspect of astronomy really
fascinates you actually my my my heart of hearts object are comets
i'm doing some research i think i may have mentioned this one of our last episodes that i'm doing a book trying to
compile a book on great comets through history
so what i'm looking at is for literary references to to comets
victor hugo's uh a tale of two cities
or no notre dame his book on notre dame in this in his introduction he talks
about a a commentary fragment a fireball hitting uh notre dame or uh the palace the
justice in paris in march of uh 1618 and believe
so i'm trying to and it actually i guess burned down the palace but there was a
riot going on at the same time so i'm trying to uh qualify whether that is
just a literary license or in fact that it that it happened actually so i like that kind of uh
historical research and and what but comments uh if i may i i'm just you know following
uh uh mr levy about his poetry and stuff uh i write poetry myself and i i have just
a very short uh little poem here on uh comet high of kataki in march of 96.
if i may i'll just read it please in gown of ice and stardust fine woven
from cloth of heaven's design this anxious bride in hurried flight
crosses the dark ocean of the night on she rushes drawn fast by fate to a
fiery marriage with her mate innocent that his wild embrace will consume the passion of her race
wow that's nice that's nice that's the first time i've heard that beautiful beautiful thank you
well glenn thank you for coming on to the program is there anything that you would like to add before we uh
transition here yeah well just to uh thank you very much uh it's a pleasure and an honor to uh to
do to be present with you folks i mean i recognize some of the names here and it's a great
honor to uh to see them actually face to face uh i was looking through some of my old
astronomy articles uh magazines and i found one from uh
let's see when it would have been uh may june 2010
uh that david wrote david wrote david levy wrote about trials of my need for
in 14 inch where he crushed it with his the roof of this
yes he did yeah and uh then there was another article uh
astral business a way of inspiring uh evening stars
so him and uh uh mr asher's icer escher i don't know
how to pronounce your last name biker yes yeah okay i've enjoyed i've enjoyed both
their their writings over the years in the astronomy magazine so it's a great
pleasure and an honor i mean these are the people i've kind of looked up to uh over the you know the past 30
40 years or whatever so it's it's a real pleasure to finally say ah i know that person i mean in one sense i do so right
right again thanks for the invite and i look forward to future so yeah we look forward to having you back on you're
welcome of course anytime that we do global star party um so glenn
thanks thanks so much uh and now now i i i definitely have the uh
face uh with the name so i will uh i'll make sure that i make an appropriate
announcement poster for you uh for the next time that you're on but uh okay we have um
we have uh coming up on is it february 15th uh
is galileo's uh birthday uh a celebration 158th
anniversary on tuesday night uh which will be a global star party so that will
be one of the global star parties we'll do uh so it's uh
you know if you're you're looking to uh be on one of the uh uh you know uh what i would consider to
be one of the really special uh celebrations that would be that's coming up soon and i think february 4th
is clyde tomba's birthday is that right
silence [Laughter] i'm gonna say it's right
so yeah we'll have to look it up for you scott i think it is february you are right it's february 4.
because you'll know it off the top of his head i was i was confused because his birthday is january 17th but yes uh
no his sorry he passed away on january 17th but his birthday is february 4th everybody's friday there we go all right
so yeah because we did like a whole global star party because february 4th i think last year was on a tuesday so yeah
it was yeah yeah so um anyways but celebrating galileo is going to be a
lot of fun in two weeks that's right yeah yeah that's right so okay all right so coming up next is uh
the vast reaches jason genzel uh jason uh is uh has been on many global star
parties uh and uh we're always um uh you know blown away by the uh
incredible imaging that he does um he is uh definitely one of the
astronomers one of the astrophotographers out there that uh squeezes out every last ounce
every drop that he can get out of a piece of equipment uh and uh so that's
that is a you know a hallmark of uh you know an astronomer with lots of expertise and
skill and so we're very pleased to have uh jason on jason
thank you scott i'm glad you're uh feeling better thank you thank you and again thank you
let's see yes which oh you've got two you've got to come on here twice because i share it from a different computer
okay all right there we go the camera so thank you about that no problem but okay
um yeah i've got two main things i want to share um kind of separate topics but
uh we can go into uh the first one which is the james webb space telescope and
we've talked about that a number of times already on the on the program here but it's a popular
topic right now because it's a uh marvel of our technological engineering floating out there in space
and uh after it launched on uh christmas eve on december 24th
took a long journey out to the lagrange two point which is a
gravitational equilibrium spot beyond the earth where it's in a stable orbit
you know far away from our planet and then any of the heat or light pollution
associated with it and so it's got a nice view out into the cosmos well that long journey um
it took um took it basically on a grand tour of the night
sky and i thought hey wouldn't it be cool if i could take a picture of it um passing by some
recognizable night sky option objects so i set about doing that um and it
was a little more complicated than i had originally anticipated but i'll walk you
through the process here let me try to share my screen
let me know if you can see it yes we can okay so um starting off here this is the the
jwst site that's published by nasa um where you can get
updates uh on its progress and and uh basically what what it's been doing
one of the interesting things here is uh this tab called or this button called where is web and if you click on that it
shows it's after you get to the pop-ups it shows it's a trajectory from launch
and if you step out here these are numbered in days as far as um
the significant milestones uh it went through as it as it
moved out towards this l2 point so you can see about 30 days after launch in late january got to the l2 point um
and it was fully deployed so now it's on to its commissioning um
but my situation here in michigan is a severe lack of clear skies so i only had
limited time to try this and so on the night of january 10th it was
clear out and i set about locating it and photographing it
so i opened up some planetarium software and saw that it was floating uh past the rosette nebula
which is a fairly common night sky object to observe or photograph in the winter sky
and so i wanted to get that shot and what that required was a widespread telescope
and i will show you what i use here
see if i can open this see this
yes right so this is the telescope i uh set up to to try to photograph the the
james webb and it's a it's a wide field telescope this is the tpo ultra wide uh which is
180 millimeter focal length wow okay 40 millimeter aperture so it's a very wide
field telescope it's essentially the size of a camera lens i mean you can see it here
um i mean astro photographers probably have a sense of scale from this the zwo
camera on the back but uh for anybody else uh this the lens of this
telescope is 40 millimeters so just under two inches and um
i'm shooting this with a monochrome camera and filter wheels so i was trying to get it
with as much signal as possible so that's why i used a monochrome camera with clear filters
and so i'll hop over to my image through this telescope
so i think most night sky observers will recognize this as the rosette nebula
but a very wide field view of it it's not that common that you see it in this this
wide field view but that's really cool zooming in
we can begin to see the james webb space telescope now what i did is shot uh 40
millimeter 40 no not 40 millimeters 40 minutes of exposure so two minute
exposures 20 of them and stacked them up and as we zoom in
here you can begin to see this streak which is oh wow there it is telescope
so that's our 10 billion dollars as we launched out into space yes
but yeah so um you know a challenging pride project but
uh i thought it was an interesting juxtaposition to see this
telescope floating out there amongst some massive deep sky objects
and they're pretty early it adds some perspective too because you're seeing
you know obviously immense region of space and uh you know uh
standing next to jay west you know you're you're a little dwarfed by this amazing
uh instrument but there it is it's just a tiny line out in space so yeah so we got this
other crop that kind of uh you know points it out and then if we look up in the corner here i've got the zoom in
of that so this is what's called the maximum stack where you take all your image in the lightest pixels
once you stack them it becomes a streak so that's 45 minutes of motion of the telescope through space at the time i
shot this it was 1 million kilometers away on january 10th it had recently
fully deployed its sun shield so it might seem counterintuitive how something a million kilometers away
could be visible uh to a to a small telescope like the one i use but that sun shield is
essentially a tennis court sized piece of mylar
with its face pointing back to us so the sunlight bounces off that
sunshield and reflects right back to earth so it's almost like a beacon out there shining
and so um one other view of this i did was to
present this in video form so these are now the raw captures you can see the telescope here you can see
my mouse moving through space over over the course of 45 minutes and then i
fade out um using the background of that other image
which is a total of four hours of exposure to to present the
background scene so zooming out just gives you that sense of scale yeah
it does
i don't know if the video is playing smoothly at all guessing over zoom it's probably not too
smooth but it's a little it's smooth enough we can see the movement it's really cool to watch that's right
that's really cool
all right so that's the james bond yeah that's the other thing i really love about jason's images too he he gets
creative in the way that he'll go about trying to capture something you know
he's trying to show us aspects of the universe from his backyard that uh
i think a lot of people wouldn't have um uh maybe there's some other amateur
astronomers who tried to capture this i know of none so except for one and that's that's you jason well yeah i mean
i've seen other amateurs it's actually still visible out of its parking orbit
which is uh what
1.5 million kilometers away so 50 or 60 percent further than when i captured it
um and i've seen other images but yeah um you know like you said scott you know they're zoomed in and it points to a dot
and you know there's a james space telescope yeah i like to try to give the perspective
here of you know what this looks like out in space
against the backdrop of some from some other deep sky objects that are somewhat recognizable
so cool all right so that's the james led space
telescope i pulled up the website here it's a good resource for anyone that's curious all kinds of specs about the
telescope and you know you can click in here and get some really they have really nice uh
multimedia images during the construction uh well here you go there's a
shot of the where is it
it was trying to show the sun shield here i know there was one with everybody yeah
there you go that gives a sense of scale in the sun shield yes so essentially when in my image
that's what i'm seeing is the reflectivity of that that sun shield back towards earth
incredible at almost a million miles away
all right so i'm keeping on with the theme of the the uh
the star party forged in stars i've got some solar images
those that have followed me know that i like to shoot the sun and it
presents some challenges during the winter time because the filter i use is sensitive to
ambient temperature it uses a heating element internally to
basically put the filter on the hydrogen wavelength and when the temperature drops
extremely low which it has been recently the filter kind of drifts off band and doesn't work properly so been kind of
dialing that in and working on some changes but i just want to show the team here that
real time views of the sun are absolutely um at your fingertips whenever you want to
see it this is one resource the uh through the nso and this is the gone
hydrogen alpha solar network so it's a it's a worldwide network of telescopes that view the sun
in hydrogen alpha and these are all updated real time you can see
um depending on where it is in the globe you'll get an update on how long it's been since the image was
updated and if you click on these movie tabs you can
play a movie of the sun rotating and these are you know continuously updated so i usually look at this as a resource
to decide if i want to go out and shoot the sun during the day and then there's also spaceweather.com
which is a great resource for solar activity and space weather basically uh
gives you tips on incoming aurora etc
all right so now we'll look at the solar shots i have just to
refresh the group here this is the solar telescope i use looking down
towards the sun but i've got a asi 174
monochrome camera which is a dedicated astronomy camera which shoots at a very high frame rate
and that is shoots in monochrome which is useful for solar imaging so that's what i use for the camera
in front of that there's a daystar quark solar filter and then this is the uh
ar152 telescope the explorer scientific all riding on a skywatcher eq6r mount
but it gives a view of how low the sun is for my location during the winter
so during the winter you struggle with um not only temperatures but also the
the altitude of the sun uh from my location in michigan it never gets about 30 degrees i'm shooting
through a lot of atmosphere and the stability of that atmosphere has a lot to do with the final
quality of the image i don't know if you intended to jason
but it looks like you got a sun dog in that picture oh yeah maybe a little bit there it is
to the left yeah a little bit of sun dog all right that's right yeah
yeah those are uh formed by ice crystals up in the the upper atmosphere uh and
probably in these these cirrus clouds here um
they appear yeah typically in the winter due to ice crystals up there
there is a another view of that filter and like i said in the in the cold temperatures when it gets down to
like uh you know below freezing or um i think on the night or the day i was trying to
image it was maybe down to 10 or 15 degrees fahrenheit which is
pretty cold i i started running into problems where the filter would go off band and i wouldn't get any detail at
home so i invented a new thing it's called the solar sock
i cut up an old sock to insulate the outside of the filter and put the new heater band inside there to to warm up the barrel of
the the filter and to try to keep it on baby
this was shot yesterday i'm sure you're paying special attention to that solar socks scott
see you i am i am i'm coming out with solar socks tomorrow [Laughter]
baton bending all right carry on but uh by all accounts it worked so i'm
back to imaging the sun after all the hiatus the detail had fallen off significantly
with the cold temperatures but using that sock and insulating and heating the outside of the filter i can
get the details back so this is a view of the chromosphere of the sun from yesterday and this is an active region
which is just rounded yeah indivisibility uh
and this is a sunspot and some this is the active region here and there's a
prominence off of one of the sun
beautiful and uh you didn't happen to catch uh or to get
a picture of all those uh filaments they've just discovered in the in the corona
there it's been in the news just lately uh there was a
coronal mass ejection um a few days ago
is that what you're referring to well not necessarily that they were all these newly discovered uh
kind of filaments that seem to be falling back onto the sun
from uh from the uh [Music] solar flares
uh no i don't i mean not in this series of images there is an interesting phenomenon which
i'm not sure if you're referring to this but it's called coronal rain that's where
a prominence actually the globules of hydrogen plasma
that exists out in a prominence which is hanging out in the sun those will
actually rain back to the surface of the sun and i've caught that phenomenon before
in a real-time time-lapse movie of this activity
well these seem to be something that that was new or something they hadn't
seen before and they were quite cons you know inquisitive about it uh
okay yeah i mean we call it all but i'll see if i can find the article okay yeah i
mean i don't think that i've caught anything you know like a new discovery here i
mean this what i'm looking at here is typical of what i can capture on the yeah
yeah this was just a few days ago do you know if that came from that so
from our solar probe or just a different observation i think from the solar probe
okay so it might be quite a bit yeah it was just they they were kind of like dark
filaments that seemed to be dropping back down to the surface and they were okay yeah
something new so yeah curious to know if it's due to this vantage point of the
solar probe i don't know if that's anything we'd be able to capture even with this a level of detail that uh
jason's got but yeah it is that does spark an interesting uh
challenge yeah i'd have to look into it but um yeah we couldn't do it further and send the
info on okay yeah and one of the things i like about solar
imaging is you know you can uh put a little bit of artistic flair in to the images
these images are captured as monochromes so they're just black and white so all the colorization is done after the fact
and there's different techniques you can use to colorize generally
i like to colorize in the traditional the sun is yellow orange
just because that's the way we typically perceive it although that's arguably not the
true color of the sun it gives a nice visual contrast a little bit of an artistic flair to the image
so this image is shot with an inverted look uh this image here is shot yesterday
also with a slightly different processing technique where it's not inverted this is a
natural representation of of how the chromosphere appears
where it's a darker structure over top of the lighter photosphere of the sun
and so these brighter regions are the active regions and the darker areas or the sunspots
that's just a little bit of a different way to look at it but again this is a
this is an active region that was shot yesterday
if you look on spaceweather.com it's this group here uh 2936 is the number
all right so um one last thing where did it go
because i've got the uh original view that i shared um as a time lapse movie you know i have
not really finished editing this but it'll give you an idea of
what it looks like in motion yeah so this is a pretty low contrast view i
haven't finished trying to boost the contrast and the details yet
but it gives you a sense of how the chromosphere moves around over time and
i forget the actual span of time for these captures i can look real quick
on the other screen here see some rotation of the sun yeah so it's stabilized on the sunspot
which gives a little bit of a strange perspective because actually that sunspot is rotating
and so you can see the movement in the limb of the sun because i've stabilized on the sunspot
so yeah actually this sunspot's rotating into view
and looking at the timestamps here i've got 17.49 so this is over the course of one
hour one hour and six minutes
amazing all right well that's what i have to
share for you folks all right jason thank you so much man yeah thank you
thanks for having me scott and i yeah as always it's a pleasure so
um we are going to take a 10-minute break we have more speakers coming up um
including uh i think our next speaker will be uh naven senthil kumar he's a young astronomer uh
i think uh still uh nathan are you still in
elementary school are you heading off to junior high at this time i'm already in middle school middle
school okay all right [Music]
all right so we will take a 10 minute break and then we'll be back uh so go get yourself a cup of coffee and we'll
see you back in 10
i will definitely indulge in that cup of coffee great presentation and
i like the use of uh the images uh kareem because
you saw what you could get when the skies were dark enough and glenn i know you've seen
very dark skies i've had the um i've had the ability to travel to
various portal zones going up the portal one and each time the first time i see a
site i go this is as dark as it gets and then i go to the next site that's
darker and i go that's even darker than the darkest it gets then i go to
portal 2 and the only difference i can perceive with my own eyes
is how well detailed the milky way becomes to where
the other all the portal zones up the portal 2 the milky way might have some structure may i may be
able to see some dust lanes but everything's kind of in a black and whitish sort of look
it begins to gain what appears to be color right around portal 2 and in border 1
it's to me it's as bright as the full moon and it shows up before the sun sets
um the milky way just appears in the sky so it's uh
it's just been a pleasure to see that it's hard to capture it in images and i've
actually tried to do so all that happens is you end up with more detail
with the same amount of exposure time on the milky way when you shoot at it in different zones
you you end up with a a deeper amount
of data that you can pick up just because it's the light coming from
it the other thing with the portal 1 zones from the milky way the light is so bright that if there's
clouds you can see it shining behind the clouds like the full moon does it doesn't do that
um in any other locale and uh the brightness of the other areas of the
milky way we're talking the galactic core the brightness of the other areas in the milky way is very evident too
and in our heart can be the only thing to shoot at our montreal border scale uh nine wasn't
good enough uh it's you know you've got to count nine full moons as our border scale that's that's kind of the skies
we're looking at yeah and i know bortle scale i've heard the
complaints of portal scale kind of being you know relative a portal one zone can look more like a
portal two zone to me it just comes down to it comes down to visibility of the milky
way and how this is one of the things i liked about the globe at night right because even though like they do put numerical
magnitudes it's not the mortal zone but they do it with these
star maps where you actually have magnitude guides and you go out and say all right i see about this many stars in
this constellation that corresponds to the 3.5 where that corresponds to somewhere
between three and four and that's that's really nice because it gives them something tangible to try to
measure it rather than walking around with uh with a photometer of some type yeah or with that you've got that scale
where if you get 21.9 or 22 then you are you're talking not only dark but i think
you're talking transparent as well i'm curious glenn uh out in
the maritimes i mean i know chris kerwin does his astronomy by the bay with uh paul and mike and stuff in
in new brunswick but over in nova scotia do you guys have a lot of outreach events that you do are you
really active in the local club what are things like down there
oh you're muted at the moment
yeah sorry glenn you're still muted
it's all right we'll chat offline otherwise
yep i'll be back i think we got a few a few more minutes in the uh break so yeah
time to grab some coffee yes not for you naveen uh you're too young
for coffee yet yes tea for you naveen non-caffeinated tea
i i don't really drink that often but i do drink milk
that'll work too hot chocolate yeah preferably
i drink that every morning i love it are you interested in uh taking part in that alien drawing workshop on the 13th
um i don't really like drawing no worries no worries but if you're interested in giving it a try then that
one's open okay all right sure
maybe
hello how are you sorry i got booted out here had to get back in who
uh who was asking me a question oh i was i was just asking about uh outreach and
events over there in in nova scotia um well um i'm only uh
like a satellite member of of the halifax astronomy club i used to live in
halifaxer and was was an active member when i was there but i'm on pei now so
uh we used to have yeah we used to have an astronomy club here but we uh
we lost our place at the university when uh professor wanakot uh
was uh who was the uh astronomy instructor at upi when he died uh we
lost our access to uh free lodging at the university and uh
the only way we could uh could get a room was to pay a hundred dollars for every time we met so uh that
kind of we didn't have a large membership so that kind of put a quash on our our media our monthly meetings and
subsequently our club eventually dried up and there's only two or three of us who get together now
uh are the others still in the area there's a couple of people still in the area who uh you know we we get together
and go out and do a bit of observing or take pictures from whatever but we've lost the balance
a lot of our members were older members uh a good number of them have have died
unfortunately um so and and some of us as you can see are
getting uh quite gray and long in the tooth uh i'm 75 myself so uh
yeah we're losing our membership we've tried to uh reactivate the club but without a place
to meet um we've only been able to hold periodic
uh outdoor gatherings you know we'll touch base by email because i do have a
contact at upei and uh i'll reach out and see if they're willing uh to step in
and maybe give you a hand to get something set up again yeah i'd appreciate it because we'd love
to get uh something going again and i mean i i miss it terribly and i know the
other members do we've also tried to get into the schools but because of cove
with the last couple of years we've kind of been push to the back burner but we were
hoping to get a uh you know a kids program going where we could go in and perhaps one one uh once a week or once a
month or buy bi-monthly uh you know have a half hour talk with with children grade
school from say do you know chris kerwin from uh new brunswick sorry do you know chris kerwin from new
brunswick no i can't say i do i'll connect you to him because he's been doing zooms into
the classrooms and he's always looking for more volunteers to help out and to to do some of these uh zooms
because it's it's classrooms throughout the maritimes he doesn't just stick with new brunswick into st john so
i can chat with him and connect you with him by email and that way i mean this is the thing is when you're in such a small
part of the country like pei it's very hard to feel connected to everyone else but right now there's
actually all of this amazing stuff online so let's get let's get your group back up and running and connected with
people sure that would be much appreciated because uh you know it's it's very
important to me and i i love passing it on to younger people that you know i hope public talks
in the parks and that here periodically i've got uh my grandchildren all uh into
it and everything so uh yeah it's dear to my heart and uh you know and we've got yeah let's let's
follow up on that and i think i'm gonna be doing a zoom talk for halifax uh in a
couple of months so i will be talking to judy again and so let's see what we can do all right
sounds good thank you awesome my pleasure
okay everyone we're back um uh and uh uh hopefully you had a nice few minutes
there to get uh ready for our next series of speakers um i always love to have young
astronomers on and young navin uh has given us now several uh
presentations uh it's when you
listen to what he has to describe you can tell how passionate he is about
space astronomy and the universe and uh i'm very certain that he'll go on to
do some great things in his life so david i'm going to turn the stage over to you
thanks for coming back on to global star party all right thank you for having me
so today i'm going to stop talk about how stars are born
in may so let me just share my screen [Music]
all right so i got the presentation
nevan do you give presentations like this uh in school
i do not you do not okay i'm glad you can do them here
sorry one second all right let's start here
sure how stars are born by me name vincenzo kumar
how are stars born stars are born in nebulae by forging pieces of dust and
gas and they expand to make stars a familiar example such a
as a dust cloud is urine nebula of course this is an image of the orion nebula
this is also another image in high contrast of the uriah nebula
all right let's go to how our stars born next stars are now most are mostly made of
hydrogen and plasma so the first thing in the birth of a star is called a protostar
a protostar takes about 100 000 years to make them complete it doesn't have any
internal temperature and pressure to begin its fusion at the center and if you see a protostar here if you
want to see it being made it's kind of like a galaxy for example the stars in the center which is right here and the
surrounding is or is all orange
um dust and gas forging together to make this young star
and sometimes light comes in to also help produce the star and also plasma
alright [Music] now the process of star formation
the first step a the stars come in a dark cloud like a nebula for example then the stars are
formed in dark clumps step number two the stars are in the pre-stellar core
which is right here and then number three is the star turns into a protostar and it takes
a hundred thousand years and d in number step number four
is the atari star it takes up to a million years to make guitar star
step number five a pre-main sequence star it takes up to 10 million years to make
a pre-sequence star step number six it takes a mate
for main sequence start takes more than 10 million years and the size is about 50 astronomical
units so this is the six steps of creating a star
a solar system typically make lives around 10 billion years but our son is
currently in the middle of his life it's like process we currently have five billion more
years to go [Music] and after a few million years it the
process also halts now the star is born
and also that and also the star has no ins in turn
now has an internal temperature and it can start producing on its own
all right my that's almost for my star person all for my starboard presentation now let's go
to my astrophotos love this
so this is my first astrophoto it's a lunar eclipse
through my eye through my telescope in my backyard yeah you nailed it you nailed it it's
great very well done now let's go to the next one
[Music] this is a picture of jupiter through my iphone 12 pro max in my backyard
jupiter's right here and saturn's about right there and they're kind of locked in the clouds
and you can see the light from over here
and now you see a seagull it's from it's we went to the chesapeake bay over um
for christmas and i also shot this through my phone
um so we were on like we were on we were in a scenic overlook on this wilder and this wild river
refuge called fisherman's island it's off the coast of virginia and so
in the south facing the atlantic the chesapeake bay
now this is another image it's on the same overlook you can see the beach kind
of over here and then like it's like a sun it's like with the sunset and you see the waves coming in from the
bay oh all right oh yeah it's the same and then you also
see the bridge over and you see like a seagull floating
and flying yes and you see [Music]
and yeah that's all thank you any questions what's that that's all
let's see beatrice hines uh who's a great astrophotographer as well said
great image of a seagull too and uh jeff uh jeff weiss says great job and uh
they're happy to see you on the program yeah thank you thank you so much for having me and
thank you yeah that's awesome thank you so much
excuse me oh okay do you have anything more you'd like to say before we transition here
nope do you nope okay all right that's great
all right so um uh up next uh we've got uh adrian
bradley adrian does uh has graced many global star parties now
with this beautiful nightscape photography he is
and he helps us to explore you know various aspects of the milky way what can be seen with the naked eye
but also and he gives lots of tips as an expert photographer
you know and how to handle a digital slr uh in these low light regions and what
you can capture at night so adrian thanks for coming back on and uh
um looking forward to seeing what you got uh uh well thanks for having us scott
yeah thanks for having me and uh so as i i jumped on early and i heard
you know uh david levy was talking about van gogh and um
how the night sky inspired him to want to draw it want to paint it
and um for me i can i understand that feeling because
the desire to capture the night sky comes to mind whenever
you know i and just being out under it um even if my images aren't as good that
night or you know things don't go as well or it's blustery or cold i still enjoy looking
up um for in our region we're not going to see too many stars
um because of the snowstorm coming into our area in michigan so last night i got a chance to see the
starlight for what could be the last time in a in a little while and uh i tend to like to be out there to
capture it before the clouds cover it so so what i'll do is i'll share with my uh
presentation layer um we'll share this screen
and i'll take our chat and move it here so
these are the images whenever i pull and copy a few images um
as i'm listening to the star party i may be inspired to um
share some of the other images some older images if i feel that they're
a part of the conversation and newer images that i take so
we'll start with the lunar new year and this is one of the images that i
have not been able to replicate i don't know if it was the circumstance of the moon rising and the cloud cover
being perfect this is one of my favorite spots to image but in a single shot i managed to get
the full moon with some detail clouds illuminating it and or it wasn't
full this was um maybe a couple days past full um
and you have the uh reflection on the lake here uh lake
huron i haven't been able to reproduce this shot and even though i have settings and time of day and everything
um just one of the shots that after some processing this is how it turned out
and so this is my nod for the the uh lunar new year
and um i'm actually hoping to print um
something for that so that's my nod to the lunar new year
um i'm also hoping to write a book about this place um this
is point o bark lighthouse park one of the few places in michigan we were talking about places where the sky gets
dark and this is the thumb of michigan and i've captured a number of images
over the last couple of years at the at night some during the day but mostly at night of this place
and i'm hoping to put them together and in a sort of illustrated book just describing
the images what i saw this night is gonna feature very prominent the
um 2021 the uh the uh spring
equinox and um the the aurora was visible
in the distance and it was it was very active but visible and
the thumb of michigan is maybe 42 north latitude so even as far down as
the thumb of michigan you can still see the aurora in the distance um
in that image too you know the way it leads your eye into the yeah
and then that just golden color is beautiful
yeah i was able to capture a few colors now if you turned around
this is the way the milky way looked when it was rising around the same time so there were plenty of things this is
like turning around from that on the other side there's the red light that's casting
that glow on this part so there's a platform here where i was
standing i come up here and i turn around and this is the view you see after
processing with the camera the milky way rising on a lake so it's a very beautiful place to image
we talk about seeing all of these stars and you know
things being forged from stars nothing's like looking up and seeing
millions of them um here's the image that uh kareem
shared with you um if you look at this image i mean this is
all you see though just look at the little stars that are in this image and you let along
the the large ones it looks vast and
looking up and seeing that naked eye is quite an experience yeah the uh
this is a familiar image for those of you who have read skies up magazine this is the same
essentially a similar region sirius hasn't risen yet this is what it looks like when you take it with a camera
that can capture h alpha data and you image enough to capture
the dust lanes this is a not as often imaged part of the milky way
and you think milky way image most folks go for the core this stuff because it's the brightest
thing there and in a portal one site it's so bright that it
clouds try to cover it this is what you end up getting
that's the there's there's m5 there's the sagittarius the star cloud
peeking through hey here's the m i think m16 and m17 or m17 and i forget
which one they're peeking through the clouds which are dark underneath
you know once you get away from light pollution the sky changes
so you know you do what you can to get away from sky from light pollution sometimes
we can't but we can go to some places that are dark enough they cast a little bit more of a bluish
hue in the sky this place is northern michigan it's still lower michigan but it's a northern part of it
and some of the nebulosity you saw that i had captured shows up this was taken a
week ago friday i braved some uh cold attempts to get on a bridge overlooking
this uh river i had wanted to take this shot for maybe a year i planned on doing that
what i didn't plan on was um catching this green glow and i turned the other way this is the other
way on that bridge sort of facing north you've got north star right here
and my processing appears to have mangled the uh big dipper a little bit sometimes
we with a wide angle lens sometimes we lose some of the uh edge
so it's definitely something to work on but here's that cygnus region um
to the naked eye just to let you know to kind of level set what you see
um we don't see quite as dramatic so this
is naked eye view this you're looking up and you're seeing the skies you see a little more contrast if i darken this
um a bit it's really close there was some auroral activity
so faint and um you know that that's as accurate as it
goes now you do a little bit of processing and then you know more of the hydrogen
alpha you pull some of that out and this is what you end up with
i still i believe i actually for whatever reason thought this might have been sky glow even though i was
looking north and when i looked at the numbers as it turns out
you know i'm saying oh that very well should have been um could have been aurora
this i don't think it's a comment i think there's something else going on here if
i i don't think i captured the remnants of comet leonard at this point you know that but this was
interesting to me i wasn't sure what artifact that was that is a meteor and
he said it can be easy to catch meteors when you do um night sky imaging
and uh let's see then when it comes to
what does the internet like when you do night sky photography colors
tend to draw in attention so getting colors like this comes in partly
from what light is available moonlight came was coming up
to the left off camera creating that you know this light here
and in processing you still have a little bit because i used it h alpha modified camera
to to get some of this but you this part of the uh el sabo river
was melted or mostly melted made this may be a sheet device i wouldn't i wouldn't try to jump in it because
you'll fall through um but this part of the el salva river behind me
was a light coming from a dam that was you know controlling the flow of water
behind me off on a bridge late enough at night that no other cars are passing
colors bring in your brings everyone else in that isn't
looking for a specific sort of scientific view of you know what's going on i do like
the objects in here to be accurate and that's one of the reasons
like last night's haul i went out and took some pictures and here you have just a star field this
may not appeal to a lot of people but it appeals to me
because um every star here it's pretty accurate now
when you process you lose a little bit of detail that you may not realize such
as this glow right here is m101
and sure enough there's a glow further it's hard to see in this image
um where m51 is this is alcade and as you know a right angle off of
alcade and the m50 the light from m51
appears i do believe it's this this area right here where it's the
light of m51 so there's there are treasures to see
even in simple night sky images that you take you've got flares
but you you've also got some detail here that is worth um looking at so
not just a pretty picture um i like things to be as accurate as i
can get it and i also like to see what i can see even if there's clouds
you sort of see the starlight coming through clouds and it produces an interesting picture
um so you know this little i believe m46 and 47 and i believe this
might be in 48 right here so these objects are in the sky when
night photographers do night images a lot of times
some of this detail gets sacrificed for the sake of making a pretty picture
and i can i sometimes do it too um i think with any of the images here
this is a portal 2 milky way when i first saw the milky way in a portal 2 sky
um some of this coloration here if i had to do all over again in fact i have some
raw images so i will probably play around with it see what i can do with some of the newer
processing techniques i have but for instance this dark nebula barnard it's a dark
barn arts nebula it shows up those things are important to me i i like things to be not just
nice and pretty but accurate the coat hanger appears where it's
supposed to appear this is part of the summer triangle there's
um let's see from aquila the eagle altair and tarzad they show up
and if you pull back i don't think we quite get denver i think my image cuts off before you get
to see the other pieces of this uh summer triangle here but
um i like everything a little more i like everything to not
only be beautiful but accurate you know and and then the then you think
about it all of these stars that we're seeing most of them are super giant and then you're also seeing nebulosity that
the camera can pick up from however many millions of light years away
and we can study it or we can enjoy it now the
the aim of most nightscape photography is you have something here that's also beautiful and the two play off of each
other sometimes i just shoot the night sky for what it is because i think it alone is
beautiful so there's there's always so with that i don't recall if i showed the
yeah i showed this one um the winter side of the milky way deserves attention from night sky
night sky landscape photographers and you can compare the portal one cygnus region this is a portal one
cygnus region i believe shot with a non-modified camera compared to
what i would classify as a good portal 3 zone
maybe a little sharp process but this stuff is definitely there there's orion
or not orion this is there's andromeda galaxy in some of my shots uh m33 also appeared
so did ngc 752 so with that as always i like to end
with a uh a bird photo sometimes
luck plays a part in some of the imaging that you do
we uh you can plan as much as you want it sometimes takes that extra
that extra lucky uh button press or that lucky um
chance exposure um much like the
one of the images i have here and most of the time you're gonna you're gonna catch a meteor if you keep trying
um and you do long exposure photography a meteor will somehow streak through your image
and i know i showed one earlier i do believe it's this one yeah
whatever this is i have to make sure it's not just an artifact i didn't happen to catch a comet um i don't think
it is and we'll have to see what that is but there's your meteor and there's your plane oh
i forget it's north if it's northbound or southbound there's even a streak over here too you
catch a lot when you're dealing with the night sky yeah yeah there's always something a lot
going on in the night sky so so with that i will turn it back over to you
um if anyone has any questions feel free to on the chat or in the you know watching
live feel free to send questions yeah um you got lots of accolades you normally
do adrian because your work is your work is so inspirational um you know it makes uh
you know it makes you sit back and just want to soak in uh the beauty of the night skies you're
seeing as you're as you're showing us through your lens but uh those of you
out there appreciate photographers i think it it also inspires you to try to go out there and get something like that
yourself so yeah yeah adrian i think we need to get you to like schematically show us a workflow
at some point i think we need to like i'll work on that we gotta sit in your brain for a
few minutes we gotta see how things go workshop is what we need
with this command be happy to do that i'd be happy to do that i would be remiss if i didn't wish a
happy birthday to beatrice hines who's in our church yeah i believe yeah happy birthday
yesterday yeah yeah i would be happy to do that and it's been evolving over time i've taken
some you know the classic astrophotography um things like using flats i haven't
incorporated them as much a lot of it has to do with the aim of the image like the the one where it was a darker
blue sky and you had the river going through and a lot of color uh the aim of the image is
create a beautiful image with some uh realistic uh elements in the sky
a lot of times it's marrying the two images i want the
i want the sky to be realistic and i want the um foreground the foreground may not be
a you know grand you know thing or like a lighthouse or
sometimes it it the lighthouse is there or something else is there but i'm trying to show the beauty of the
night sky so no but you even do a great job progressive work you do a great job framing your photos without using
something like photo pills or something where you have to really be careful of exactly when you set up
you have this eye for getting an incredible foreground to frame what you're trying to show us in the
background i appreciate it and you know coming from an astronomy background it means i don't
necessarily have to use photo pills i could use sky safari use the same tools that a visual observer
would use we're trying to look at certain things in the night sky so as far as those milky way shots rising
um three in the morning for those you're looking and you're seeing okay
the core is coming up at three in the morning most of the time for the for the photography side of it
um oh some photographers will learn the astronomy part of it learn enough to be
able to say okay if you want to frame the milky way core you got to get up at this amount of time and then
they'll do the planning the detail in the milky way
sometimes it can be made to be beautiful but it sometimes you'll have the the rest of
the sky just completely blown out or the sky masked out by the processing
so you end up with a portal through your portal um four zone
the milky way looks like it belongs in the portal one zone and it's uh whatever you know it's
turned into a beautiful composite there's a i think there's a time and place for composite shots they they
spark the imagination and i like the angle that i come from is i
appreciate the night sky for what it is and so when i'm shooting at the night sky i'm
like van gogh i'm simply trying to paint what i see and cap you know instead of painting
what i see capturing what i see and just transporting you to all of these places
where i'm seeing it even if i'm not seeing the exact detail i know it's there are you telling us don henley's
going to write a song to to promote your book for you maybe
i'll have to ask him but first i got to get to writing this book harold has already ordered pre-ordered a copy so uh
right now on explore scientific you can pre-order adrian bradley's nightscapes i'm gonna get the work on
that book 620 page book i
in the portrait it's fantastic there you go yep and uh
yeah that one of many books of just chasing the night sky the southern hemisphere one will
will happen i have to uh convince myself to get down there
and uh maybe even soon but again thank you all for having me
i'm gonna look through the comments thank you all for the excellent comments
it's uh it inspires me to keep going i mean it's the night sky inspires us all which is
why we're here it's why we you know we're glad you're well scott and we're able to put this on for
everyone that's across the globe you know it's i stayed up late last night knowing i had to go into work in the
morning because the night sky is uh going to be gone for
a week or so thanks to the snowstorm coming in so right so this is my way to
address it all right scott i'll give it back to you i'll be talking all night so you better thank you
adrian thank you so much for sharing again all right thanks um
uh up next we have uh uh nicholas arias also his nickname is nico
or nico the hammer i called in hammer time with nico so nico it's great to have you back on
global star party uh uh nico what is the name of the the city
that you live in in argentina uh good night scott well i really missed
this csp it wasn't a long week yeah
this one for me too you know so yes and and it's really nice to see you really
okay and in a good way here i live in uh in a city it's called
banfield is outside of buenos aires city like maybe
50 km 15 kilometers of the capital federal in one side
okay now i hi to everyone uh i i hope you are all okay and yeah you are i i'm
outside right now with my scope i'm here with my daughter that
she wants to say hi hello hello she she was she was waiting like an hour
because uh tonight i'm with my both of my kids and and she was waiting that's
great to say hi okay yeah tonight i'd like to share
something let me change this are you seeing my screen
i can tell you're sharing your screen it's not quite there yet yeah there you go
yes okay well uh tonight uh as i had uh
not know much time i i take to my astropatia
my my scope my six inch scope with my equatorial mount so i can track
what i want to show you and as you can see this is real now live
the carina this is a a live view of with instagrams of
exposure and uh the topic of night always drive me think
about the the power of the stars and and and the
explosions are and it always took me to think about eta
carina that is a star that blows my mind and er
not just because it's a a real giant star that one day will become an
ipernova not even not all of that
but this particular star has a has exploded
at least two times a exposing a material and here in the carina nebula
if we close up the image
we can really see the homunculus nebula
that is a a little nebula like a
planetary nebula and let me show
you you need to to low the exposure because the star is so bright that you
cannot see it let's let me change some
parameters to find this
okay this is the star as you can see it's really really bright if if i take
a one second exposure the the star is really bright but if you
live through your telescope right now yes yes it is live now
if you drop the exposure let's try
maybe a hundred mile seconds you can start seeing
around the star the little nebula that is the homunculus nebula that
do some zoom can you see it
yeah around the star yes you can it's like a fake phase yes and it's it's amazing that uh
with with the scope with an eyepiece if you use a a big magnification like 200x for
example you can see uh like ears around the star it's a
beautiful nebula to watch you can see uh really
really shy behind behind the star the raider star and a few nights ago
i took a picture of that with my dogs on and let me find it
so you can see how you see
when you stack these images and
here we are this what
you can make with oh you can definitely see yourself now yes and and stacking a
lot of images it was this one was maybe 500 images staggered
and i have another one this one
and you can see even the shape of the the two uh levels i i don't know how to say in
english it's like the the two bubbles
around the star and the the bikes that there is a a really nice picture of the
hubble telescope of this nebula and this is one of one of my my favorite
objects to to observe in the city because when you are in a
in a great sky the the nebula hide this
you see all the nebulosity but not this little nebula
that was discovered here in argentina for enrique gabriola
in a bosque allegri observatory cordova
but it's it's it's amazing because you have another this guy object
uh hiding in a really big deep sky object like
carinae you can see we were back with one second exposure
and there is impossible that you you see there that little nebula because
all the nebulosity around
let's wait for the camera and there you are
there is the the k-hole nebula in the center
and well that that's all for tonight i i
i was waiting to to share this to to show yeah
in the big karina you can find this hiding object that is really beautiful to observe with a with
an eyepiece yes next time i'm in the southern hemisphere this is
definitely something i want to observe so yes yeah and here in the uh
here we have uh right now it's about 60 degree in attitude it's really really
high in the sky right beautiful um uh before you go nico what
what what uh what telescope are you using tonight uh tonight i am using a
a six inch a newtonian telescope it's a hogan a
[Music] okay wonderful
wonderful yeah amazing what you can see with the six inch telescope and uh
obviously with my 10-inch dogs it's amazing to observe this but
tonight i i prefer to use the the equatorial mount for the
for the tracking so you can i i can show you both things the
the nebula with exposure and then the homunculus nebula
so i shared a link on wikipedia about the uh
homunculus nebula [Music] a little difficult to pronounce
you said it was uh uh discovered in argentina is that right yes
it was discovered here in argentina for enrique gabiola in the observatory along the province of
cordoba that is called a bosque allegri observatory
i i don't remember now the the year of the discovery and the the name the among us
it is brings a from ladding that a little man because i don't know he
he observed and thinks about the little man
very cool very cool thank you very much nico no thank you scott thank you and
enjoy your family time take care okay great presentation i i think i will
be i will be there for minutes because uh the the little one of my kids is yeah
get asleep in the in the couch and my daughter is watching television so
i i will be here yep you're welcome to hang out with us that's great thank you okay
okay all right so uh we've gone uh from argentina and now we
will go to brazil uh to uh visit with uh marcelo dr marcelo
souza uh marcelo is getting ready uh he's starting to make preparations for his
aeronautics and astronautics uh symposium that he conducts each year
this is the 14th one i think that is coming up in april is that right
yes so uh so i will i will turn this over to you
uh uh marcelo by the way marcelo is uh the editor of sky's up magazine and uh
i will put in a uh link so that you can download your copy your free copy of this global astronomy magazine
nice turnout thank all of you hi yeah i also had to go with a live streak
it was mute for me also here in brazil now a lot of people
are getting convinced you know and uh i would like today
to talk about something that will be maybe the most important astronomy event
here in brazil that is the eclipse
the lunar eclipse only 16. it is not a picture of the
lunar eclipse but here that is because i i also when i talk about eclipse i
like to show first this image that for me is fantastic image that is a solar
eclipse from the international space station
this is fantastic but here and here
this is part of the presentation that you we do here on different sides of the
moon and the earth here is a picture that shows the moon and the earth as we
see from space there is a american uh
spaceship let's look at this picture and this is what you use as happens for us here when they talk about eclipse and
that we are preparing material from now because this genome eclipse here is very popular
here and we have a lot of people that wants to participate the biggest event that we organized here
was the observation of lunar eclipse had more than 10 000 people that participate
in our seats and and today's eclipse you know on may 16
it impossible for us to see audi eclipse from the beginning until the end of the
eclipse i i think that's how inhouse south america will be possible
it will be a big festival here and part of the united states i think that
florida and very possible to see how the eclipse here's what we
use it to show why we don't have how the time eclipses
because of the inclination of the earth of the moon [Music]
in when we compare with the ecliptic that is the art of the
earth uh around the in the sun but
i will not talk about this because all of you know everything about these it is
is i'm going to show what you is the hyphens to use for the eclipse is here
and now i i would like to show is uh an activity that we are planning to
do this year educational activity that we did uh four years ago five years ago four
years ago in 2018 that was the last video clips that
we saw here and here we see the main date that's uh dot com that's a
fantastic one please and here you see that for us it will be a fantastic time
on may 16th house the south america uh
central america part of may mexico united states and canada would be
fantastic you can see our defeats and we are organized from now because
many people were trying to participate he has information from our city campus here in
brazil we see that for us here the partial eclipse begins in this time
that i'm talking now that you begin the eclipse for us here in brazil and you can see how the
eclipse the apache eclipse ends near 3am here in brazil
here on seats then it will be fantastic for us but you have to pretend to see how the eclipse
any this will be the first and most important event for us we
will have another eclipse but this is the first one in 2002 for us and the activity that we
are going to organize is the same that they did in the past
that's it when you have your partial eclipse here you can imagine the size
of the shadow of the earth it's a shadow scone
this is part of the shadows form and they use this as a reference to do
these activities we ask the students to take pictures or
make drones of the partial eclipse and then using only
geometry they trigonometry they can add
no distance from the earth to the moon in the moment of the eclipse
this is why to ask the students to make the calculation using only using all the similarity of
triangles here to to solve this this is fantastic because
it is what they did in the past it was cool we can do this again and now everybody
has as much fun with cameras with zoom
telescopes that you use oh can draw what they they see and they came this is a reference to
that then we compare if this is a small one
that's here is the coin the shadows funny let's have here because
many people don't know because that's the shadow that see you see
over the moon is not the size of the earth
many people think that is the same size but it's not the same size of the we have a shadow spawn and then
if it is information we can calculate the distance from the earth
to the moon in the moment that they took the picture
an example that we did well and this is the material that you we give to the students
and to the teachers teachers they organize the
directive during the event after the eclipse observation
well i have here approximately the distance that will be like this
three 362 000 kilometers that would be this distance
that they depends of the time that they are going through to make
is near this that they need to find and we use this now that
whenever you organize you ask you people to use a uh template to help them
to measure with naked eye then we organize this template then they have
the here jerusalem of the size of the shadows
the shadow of the earth and the size of the moon then they can use these as a reference
to make the countries the perception of approximately the size of the
air of the shadow and with the information we give to them
the the size of the the diameter of the earth diameter of the
sun and the distance from the earth to the sun with the information then
can find the distance from earth to the moon in the moments of the greens
this is a an example that is possible to organize
activities that can motivate them and show that these mathematics they need to study
mathematics for everything they only
they did everything man they measured distances between the earth between uh
they knew the stars that are studio
to us using only trigonometry that is something i know i don't know if i'm say
correct it's trigonometry trigonometry you said it exactly correctly yes yeah
that's that this is one of the most powerful that they had in the past
to to study the sky then doing this they can also
feel i like the in the past the people felt when they they measured this
they solved the problem like this i i ever showed this image before i
didn't forget that it was the event to see the lunar eclipse totally keeps in 2018 here
they had 10 000 people on the bridge of the and we had
ten thousand people here ten thousand ten thousand wow that's huge during audi eclipse we
had five telescopes there but we can't connect the one with the other because you have a lot of people between in
between the hand it wasn't possible to have any kind of contact remember you can't see here because we took the
pictures near the telescope but if you take the pictures
uh from the beginning of the breeze you you can't see telescopes you will see on a lot of people there
that try something that unexpected because we we asked to close one of the
lines of the the bridge then when i arrived there you have
policemen there you have people selling hot dogs
beverages drinks a lot of people ended the bridge was full of people
here you can see here and it was transmitted live by tv but two tv channels here you know seats
because a lot of people are there then they participate out of newspaper it was
the biggest event that we organized the first one that you organized in in uh
the public square downtown we had 2 000 people in before the eclipse the other eclipse
before and when we did in the maybe because they i they
knew about the they closed the bridge and a lot of people
would like to see what was happened and then they participate then we have
so many people that it was the biggest event ever organized the year
of a popularization of science in you know wow wow this is the reason that we are
preparing the lunar eclipse from now let's say they just little eclipse for now because may is near never having
four months less than four months to organize you know marcelo it's nice to see some a
gathering like this because you know we're constantly being bombarded in the news with you know
conflicts happening where you know huge masses of people are are suffering
because of various you know political things that might be happening around the world
and to see people coming together obviously for joy and peace and to learn
more about science and the universe that they live in this is really amazing and this is this is uh just just one of the
things that will be your legacy marcelo this is great yes it is celebrates a lot to do and do
the job savage was the moment that the moon was in total eclipse
everybody clapping here then we organized a big event i hope
this year if you had the help yes we are going to organize a big event also and
we are beginning now the organization of these events and this is our international events that we
are helping in april 22 23. everybody is invited to you to visit us
and be welcome here if we arrive everybody that arrives in brazil you have place to stay here or
see to transport to come here everybody that comes that will be very welcome here and the we are trying we
will organize even with the pandemic period now but we hope in april we have
conditions to have it on site events and
this is we are planning for now that is our biggest big event that you organize every year
this is for events that you participate in here with yours
i hope you can visit us again you'll be very awesome
and this is part of your planning for this year this first semester
and the next week we will begin activities in schools here as part of the project
uh young style of tomorrow in schools here we could support you for the united states consulate here here
junior we are business schools last year we began in october and
reveals that 19 schools and this year if everything happened as
we are planning we are going to visit 50 schools
we stay during two days in each school then we will be
100 days in schools until october wow
well thank you very much thank you very much
for my pleasure to be here thank you so much thank you
that's great and uh here there we are okay
so um i want to thank everybody for uh
um you know i want to thank of course our presenters for uh participating in the 81st global star
party uh and for our global audience that's you know watching from asia all
the way out to europe and down into south america and all the way across the americas it's
great i was looking at this map of the
lunar eclipse and we've got a good swath of the middle and eastern part of the united
states i'm glad to say that arkansas will be in that uh what what they're calling the blood moon
on uh on that uh may 16th we have many more
global star party programs coming up including one that we'll do from september 21st
through the 25th live from the oracle state park which is a dark sky
park in just outside of about an hour north of tucson
arizona and that will be the arizona dark sky star party so we will be
offering up tickets to
be an astronomer at the event but we will it will be a mixed hybrid event where we'll also broadcast
the lectures and we will invite the presenters that normally appear on
global star party to be part of it as well uh so that we can reach around the world with this uh in-person event so
um kind of an experiment for me to try to uh host a real star party and and to
broadcast it at the same time so that we'll we'll see how i pull that off
um we will be amazing scott we'll do our best
i'll drink lots and lots of coffee okay so but uh
um let me uh let me remove this here we go
this is uh those of us are still uh with you but we want us again we want to thank you all
for uh participating and um uh you know uh we will
does anyone want to wrap up and add anything else before we call it a night
now as always thank you scott for for make this happen and it's a pleasure to talk with you and
with the other presenters and with the people on youtube and on in the other in
their webs that that are participating in every csp is really really funny
yeah this is really great you know i was i was kind of reflecting on
you know we've done more than 80 global star parties now and um you know but i see that it's it's the
audience and the presenters i think that that um
uh that you all y'all are
are using the internet in the in the in the manner it was intended to be used
you know to bring people closer together um you know unfortunately it took a pandemic to
really focus us that way but uh you know we are
um you know we're only a computer screen away right now you guys have been
chatting with us live we've been interacting with you as much as we can i hope you really enjoyed the uh
presentations tonight and we'll be back next tuesday okay so
until that time keep looking up thank you thank you good night everyone
stay safe clear skies
