Global Star Party 143

Transcript:

[Music]
an Einstein ring is a very cool feature of gravitational lensing where a background Galaxy gets stretched out
into a full ring around the foreground lens molten ring is a a really
interesting case where it's one of the largest galaxies that forms a near complete Einstein ring the molten ring
you have a very large cluster of galaxies that has magnified this background
Galaxy Einstein's theory of general relativity is really sort of what predicted these Einstein rings in the
first place he created this whole machinery for how gravity is supposed to work matter would tell SpaceTime how to
curve and SpaceTime would tell matter how to move and then as you have light moving through this curve SpaceTime that
those equations led to the prediction that this light would almost move on what seems like curved paths and cause
the phenomenon of gravitational lensing which is where this light gets essentially bent and distorted by a
foreground lens like a Galaxy cluster and creates these these stretched out images that are magnified of these
distant galaxies that we see it's definitely a bit of an optical illusion so if you were to take the uh
gravitational lens completely away then these background galaxies would just look like you know the normal everyday
galaxies that we see at these distances uh and it'd be a lot harder to to pick apart what's going on in their their
inner workings so the the gravitational lensing effect it is kind of like looking you know at a funh housee mirror
it makes the the background object appear uh a little bit bigger a little bit distorted you know just like you go
to a a a fun house and you see you know your head looks gigantic your body looks tiny uh it's a it's a similar effect but
we can use it for science as opposed to just you know looking at at ourselves and saying oh wow that's kind of funny
the Hubble Space Telescope has definitely taken the clearest images of the Einstein rings and they've really
you know verified this part of Einstein's theories of general relativity they've really you know shown
us a lot more about how gravitational lensing works and really sort of push the limits of what we can learn about
these distant galaxies with gravitational
lensing [Music]
[Music] conclusion we've come to from that is that there's a significant spherical
apparation appears to be present in the Optics and that we should be able to fix it in our insurance program I was not
cynical enough yet to have an item that says we put the wrong mirror in the telescope
10 and we have a go for main engine start four that was not part of my
equation and that that hurt LIF off lift off of the sput Endeavor on an ambitious
mission to service The Hub Space
Telescope the space walking is an athletic event okay I got to f fix this thing
what are the tools come up with the tools and what is the motion of the tools and so I look at the tools and me
as a dance like an athletic event and I trained with prime athletes but you know the people that had GED and and seina
and and everyone else with the right kind of spirit it's just it's
teamwork it's teamwork that's what it is all the components that we might change
out they were designed to be changed with a space walk so that's flexibility
that's looking for the future that's designing for failures a perfect Space Walk is one
that you pull off just as accurate as an Olympic high jumper here's what you do
and so I Envision here's the problem and of course do not have the right solution
right away that evolves the the final motions I'm going to
do watch your right hand I have you okay call me away
there's no doubt there public pressure there's no doubt the results people are waiting to get it fixed and a lot of it
should not have happened the mirror floor was inexcusable but the world is
not perfect there is public pressure it's important to people to get that thing fixed and so that's the
consequence you feel the consequences you have practiced every
one of these Maneuvers literally hundreds of times and you've gone into those water tanks to practice it what
was different about it when you were shoving that piano sized camera into the Hub
yesterday so uh yes we practiced for hundreds and hundreds of hours we uh we
tried to identify every kind of surprise that we might run into I've been running scared really ever since I got assigned
to this Mission and the casy thing was surprise but I think even Way Beyond that I certainly will not relax until 6
weeks or two months from now when we see how the solar race perform we see how the DS perform we start getting Optical
images back from all the all the instruments and see if the aberation is corrected at only at that time will I
kind of relax and think that we have gotten the job
done the relationship with the crew was perfect all the way around it
was it was marvelous we had a great crew we landed in the shuttle cu's coming
downstairs I I had gone down to the m he's coming down he looked me in the
eyes and said story I am proud of
you enough to bring me to tears story I'm proud of
you that was very nice and I'm happy to announce today
that after its launch now in 1990 some of its earlier disappointments the
trouble with Hubble Is Over yeah that was impressive my first
view of the repaired telescope but of course there were moments earlier than
that you know when Claude picked it up and let it go and that's my sweetie and we're
leaving we think we got it all done we think she's you know that was a big
moment too when we're leaving there she goes we're
leaving but it was Galaxy M100 oh my
God what it was outrageous picture I don't know if it brought me to
tears or not before this flight and during the flight actually it's been built as very important for fixing Hubble for demonstrating orbital
servicing and in some sense for showing NASA can still do really difficult missions and do them well to you what
was the most important reason to go do this mission I describe it as NASA had the courage to
go for it all to do absolutely everything on Hubble that it needed doing they they dared they had the
courage to go for the whole thing in a nutshell I think uh what was it all about it was NASA had the courage to go
for it all it was just a massive part of part of my life incredibly fortunate
that I got to participate in uh in that machine that I got to be part of it
hello

well hello everyone this is Scott Roberts from explore scientific and the explore Alliance and I am here with my
co-host uh David Levy let's bring David
on there we go through the magic of zoom and the internet we're uh we're across
the country from each other but we're right next to each other too so um I just want to um uh say that uh you know
that our our theme this this uh 143rd Global star party is a is Journey and
we've all had amazing Journeys in uh our understanding of uh of astronomy and
learning about uh uh the night sky and all of its amazing wonders that are out there uh David has uh taken all of this
uh many steps further with all of his discoveries and um you know diving into
the literature of uh of astronomy uh and uh often waxing poetic and finding
amazing poetry to recite here on global Star Party David thanks for uh hosting
this with me it's an honor to uh to do this with you and I know that all the speakers the presenters on global Star
Party feel very honored to do this with you as well so uh I think I think it's
wonderful David I'll I'll turn this over to you uh and you can kick it
off well thank you Scott Roberts and it is wonderful to be here to celebrate the
theme of journeys of course we started with stories journey to repair the Hubble
Space Telescope just in time to capture a few good shots of a comet colliding
with Jupiter 30 years ago this year and uh but I'm taking the the theme
of Journey personally I'm looking at all of the journeys that I've taken in my life my
life's journey to enjoy the night sky and physical Journeys all over the place
and I haven't taken too many in the last year but it looks like I'm going to be taking quite a few coming up I am
leaving next week to visit San Diego to celebrate the birthday of a close friend
of mine Jean Mueller who um who was uh
really was and is one of my very closest friends for life and then in April I
understand if I behave myself I will be going on a journey to see an
astronomical event I forget what it is but it takes place on the 8th of April
and I better be there and then right after that I just found out a few minutes ago that I'm supposed to be at
NE and I had no idea about that but I found out about it and so that needs to be
arranged and I will probably be there and uh to celebrate with good
friends and uh then the month after that I will be in um Europe at the star use
festival and uh with much the same friends and other friends but in Europe
but of all of the trips what which one do I want to celebrate today right now
that is a journey that I took in 1974 I went to New Orleans to visit my
grandparents I then went out to uh I then went out to
California where I visited the uh the space the the uh 200 inch telescope and
I started to walk towards another smaller telescope and I got pushed to the side by someone who said
this is private you can't visit that telescope and I said well I'm just going to go visit the outside of it would it
be okay and he said well I don't think anyone would mind if you're just gon to look at the Dome that's the
18inch the first telescope ever put on poar and I visited it for the once and
only time until I started working there with Sheen
and Carol and Shoemaker on March the 23rd 1993 at that
telescope I took the two photographs that led to the discovery of K sh maker leing n but the main part of that trip
in 1974 was not
palar it was actually the visit to delos
Ohio where I visited and met for the first time lesie C pelure and that
brings me to the quote ation of today it comes from uh from his book Starlight
Nights which I still maintain is the best book that I've ever read if I were
at in a desert island if I were if I
were on a ship say and the ship was sinking going down into the middle of
the ocean and and they said okay it's the ship's going to sink but we have a
library that contains all of the best books ever written and before the ship
sinks I want you to each of you to pick out your favorite book the book that I
picked out was Starlight Nights and uh from from Starlight Nights I'm going to
do my poetical quotation from Wesley peler within historic times 28 visits by
H's Comet have been recorded on an early trip at which witness the defeat of atillas the Hun in ad.
451 it arrived in time to preside over the Norman Conquest in
1066 in the year 1456 the menacing appearance of the Comet so alone Pope
cxus de decreed he did something to several days of prayer and established
the midday angelis with a great clanging of bells he then besought the comet to to visit
its wrath solely on the invading Turks in 1607 it was watched by both
shakespare and Kepler and I like to think that it was also seen by Captain
John Smith and Pocahontas in the frontier Skies of Jamestown and there's more on the
following trip around in 1682 the comet was observed by hlee himself who probed
into its periodic past and bequeathed to it an honored m that it can bear with
pride throughout the solar system by 1835 when it returned Affairs of Earth
had speeded up many a canal boat traveler looking down could see the comet glowing on the surface of his
Highway Humanity himself had taken to the skies when the Comet last appeared
in 1910 for he was making fledgling flights of perhaps 100 miles and here is
where we get to the fact that Starlight Nights was written in 196 65 published
that year before hlee made it visit in 1986 and here is the conclusion of this
wonderful piece of writing by pel in 1986 our historic visitor will be
visited in turn for in that year a spacecraft from the earth will hold a rendevu with H's Comet out in space who
would venture to forell the Wonders and achievements which the comet will witness in that distant year of
2062 or will Humanity itself prove periodic will the Huns be back
again thank you Scott and that is the quot thank you that's
great wonderful okay well um our next speaker is uh none other than David ier
David AER has spent uh the better part of four decades uh with astronomy
magazine he is the editor-in-chief of the magazine uh he probably knows more about
galaxies I mean as far as somebody that can just you can sit down and have dinner with and he can talk about this
galaxy or that Galaxy I mean just from memory he can tell tell you uh you know
features of the galaxies themselves uh who discovered them how far away they
are uh what you know what group galaxies are part of and all the rest of it he's
written great books about it um and uh you know we're very lucky to have him on
global star party as a regular so um I will turn this over to you David thank
you so much again for coming on global star party yet again uh I don't know how
many of these you've done now but I think it's going on maybe a hundred and
uh so that's uh that's quite a um a feet
so um David Ley and I have done uh well it's now 143 so um and uh but I think
once you get past a hundred David you can consider yourself like a
native of the global Star Party ecosystem you well I'm honored for you
to say that and it it's great to be on with you guys thanks to you Scott and and thanks to daved as well thank you
and you know we're we're brothers in being diluted by galaxies yeah and loving it so I'm
looking forward to David's lecture today but perhaps you could mention a little
bit at the start of your lecture I would like to know who got you the job at astronomy magazine centuries
ago well I had a lot of Old Friends one of my closest Old Friends at that time was David Levy um and you you I think
you're familiar with that guy um and he was involved in my relationship getting
to know Richard Barry and Robert Burnham and it's been actually the full measure
of for it's actually been 41 years now um so it's about time I get out of here
at some point but but uh yeah those were the days back uh when when I when we were all much younger um and Richard was
uh running the magazine and and we all got to know them David you were writing for both Astro and
I think at the time and yeah I started writing for astronomy and then sort of Switched past
to everybody's annoyance and uh then switch back again to even more people's
annoyance and now I'm just doing my Skyward article that gets published in a
lot of journals and uh magazines and stuff all over the world I've been doing that and
a book is going to come out one of these years based on the articles that I've written over the last 20 years for this
latest column that I do is that right wonderful it is right and I've never
written a book before so it'll be fun David you've you've you haven't gotten
up you've done 140 talks you haven't done 140 books yet but close but close
that's right I think between the two of you you've done about a hundred books so
uh both I mean the audience is is watching both of you now and uh and they
fully recognize the contributions that both of you have made to the astronomy community and uh so uh you know we're
all very uh we're honored to have have the two of you uh with us and uh you
know and I think that also that your friendship your um you know the the
interactivity that you guys have had with each other to make the amateur
astronomy community and probably the professional astronomy Community what it is today uh you know um we owe you both
a great uh amount of thanks well the honor honor is mine and
but I think this is David's time so let us turn let let him okay we'll let him
talk thank you Scott he's gonna talk about one of my favorite things so you you've been a part of that friendship
Scott also for a long long time and thankfully David was so kind-hearted that he took pity on this dumb kid from
Ohio who started a publication and wrote for that publication too and helped to make it what it became as well so we've
been Pals for a long long time um and it's an honor to be here with with all of you here so I'm done for the moment
talking about the Civil War you know I think I heard Applause as far as sou as Fort Sumpter there um but uh now I'm
back to talking about objects over over and over and over again we haven't run out of those yet so I'm going to share
my screen and see if I can share the correct screen and see if I can start a
slideshow and you should be seeing Centaurus a which has nothing to do
whatsoever with what we're going to talk about well it is a Galaxy but we're GNA talk about a different galaxy we're
still in the far northern sky but we're working our way south and by the time
you know of the next solar eclipse 21 years from now in the United States we
may run out of these objects NGC 597 though is a really good Galaxy partly
because when we talk about Edon galaxies the geometry of how we see galaxies near
us in the universe most of them are not really precisely Edge on this one is
you'll see a picture of it here it's really very much Edge on and it's an sa
Galaxy it's in Drake in the far northern sky sometimes it's called the Splinter or the knife edge because it is so
narrow it's a short distance in the sky from m102 which there's a controversy about
for its identification too but we'll take it as NGC 5866 in the classical
form uh this is an 11th magnitude Galaxy 597 that is it measures almost 13 arc
minutes across and we see its essentially completely Edge on it is a
member of the m102 group which is about uh 53 million Lighty years away roughly
the same distance as the Virgo cluster uh here from us but in a different direction this is a prototypical warped
spiral which is also an unusual Galaxy relatively near us in the cosmos in 2006
a team of astronomers announced that they had detected an extensive tidal stream surrounding the G Galaxy this is
indicative of its earlier interaction um with a warp in its disc and so it is
undergone some chaos and some tumult with galaxies near it in the past but
it's relatively isolated now so it survived that encounter as we know
galaxies because of gravity although generally the Universe At Large scales is expanding galaxies like to play with
each other in tight spaces and they often distort the shapes of their
neighbors this galaxy has a very low metallicity and a very small number of giants it has a huge population of dwarf
stars so there's not much star formation going on in this galaxy for a long time
into the past which is a little bit unusual um there is one Supernova on
record in this galaxy in 1940 that was a 14th magnitude exploding star so it's an
odd duck this galaxy for four different reasons here which makes it a little bit
interesting especially if you want to really see a good example of an Edon uh
spiral this is again borrowing from Ron Stans a great interalar deep Sky Atlas
you can see he labels it as the Splinter Galaxy here m102 is just a little bit uh
to the lower right there and we're not far from some other well-known Draco
galaxies as well here's the Galaxy and you can see that
it really is very much Ed on we're seeing almost an equaline view of the Dust belt that uh goes around the bright
disc of the Galaxy there so that's about as precisely Ed joh as you can hope for
in nearby galaxies in the universe uh this is interesting it's an
unusual shot uh this is from Spitzer this is infrared uh shot of NGC 597 and
the pinkish stuff here is dust so you can see how dust dominated and that it's
relatively inactive as far as star formation goes um and that there's some
sort of uh younger more active uh uh areas near the center of the Galaxy but
not much going on in terms of star formation here so that's it I just wanted to throw
there there'll be more to talk about you know and less with some of these objects that's a fairly straightforward object
but if you want an edge on Galaxy that's a good one to go after if you're in the northern hemisphere there's some other
breaking news here I don't know if any of you have heard about this yet but we're going to have an eclipse in North America this
year um I I don't want to shock or stun or surprise you but this is going to be
April 8th of this year we have a an issue that is a special uh issue that is
full of Eclipse coverage very much like the one we did seven years ago has great
maps in great detail from Michael Zyer his Great American Great American
Eclipse company Michael Bach has written a number of these stories that tell you how to get the most out of your viewing
as well as features by Rich Talcott and Steve Oma and others so this is a
special edition that is packed with everything you need to know for the Eclipse which presumably you're already
geared up for and if you're a good person and an astronomy magazine subscriber you will be getting this very
shortly in your mailbox and if not you still have time for
self-improvement the same right okay you can still be good okay we're trying to
help people in this world well most of us are there's American politics going
on as well but most of us are actually trying to help other people okay believe it or not and this is the way you can be
very well informed for this big event you have to wait a long time in the United States of America for a good
Eclipse uh thereafter 21 years so um you know if you miss this one the the only
one that's going to Top This one for the rest of our lives any of us who are talking now will be in Egypt on August
2nd 2027 where you'll be able to see the eclipse pass over the Temple of Luxor go
across the Nile see the Valley of the Kings in the valley the Queens after the eclipse and the odds there of a clear
sky are about 99.8% in August so that's going to be a
hard one to top the Egyptian Eclipse but it's a little more convenient here to see this for Americans uh this year so I
encourage you to see this one wonderful then finally at long long
last we have an official announcement and tickets on sale for the starmus festival starm 7 Which Scott and Michael
bit and others of our collaborators David will be there speaking um I'll be
there hosting part of the event and we have an astrophoto school going on Scott
will be helping us run a star party which will be mo excuse me modest and we expect that we'll only have something
like 6,000 to 8,000 people there um so it's going to be you know a small
undertaking this is going to be in May of 2024 coming up fast year you can go
to star.com to find out now about tickets the tickets are very reasonably
priced they're inexpensive I think it's fair to say and it's not hard to get there because it's actually very close
to Vienna Austria which is a major destination in Europe for
aircraft so there will be many many astronauts Nobel Prize
speakers uh rock musicians speaking there as well as playing and Performing
and even people like Scott and David and I will be there as well so we look forward to seeing you uh in Bratislava
Slovakia in May and if you don't make it there you will have to perhaps read
about what happened there without you so we hope to see you there that's right that's right Scott that's all I have for
tonight well staris is definitely going to uh be a mind-blowing event um uh
having participated last uh not last year but the year before um it was just
amazing and kind of H gosh uh you almost feel like you're in a dream state
because you're surrounded by Nobel laurates and and uh just brilliant
people you know but uh uh it's a very relaxed setting and uh um
you know just uh to be able to sit down with rock stars and Nobel laurates and
to sit down in the audience with them uh you know it was just uh there's nothing
else like it you know so if you read you should go to the stars.com website I put
it on the chat there read the testimonials I mean that you know guys
like Stephen Hawking who is one of the founders of it I mean just talks about it glowing saying I sure hope they
invite me back you so we we did invite him back yeah oh yeah yeah that's right
that's right but it's just it's superlative and the music that was uh
produced there also very original you know to sit back and watch Brian May uh
perform with uh I mean last time he was with the Armenian Children's Choir The
Armenian Symphony and you know Brian May and other guests that he had on and uh I
think much of it was unrehearsed uh to some degree but it sounded so tight so
good that uh you know I I wish there was a recording of it for other people to
hear it it pretty much was rehearsed very quickly but these guys are so good
and of course you know Rick Wakeman should be back as a legend on keyboards of course in rock and roll and you know
Peter Gabriel and Brian Eno and others are on our you know our friends of the board as well or on the board for Peter
so you know we'll have a lot of musical stuff there it is something that you kind of go a little numb and say you
know wow is this really you know it's a little bit of a sensory overload there's so many people you can see who the
speakers are we'll have Jane Goodall there in person who has joined our board now uh speaking about primatology and so
on but it's a who's who not just of astronomy and cosmology but all the
sciences and astronaut and space exploration technology there's going to
be a big Focus this year on AI artificial intelligence where things are
going uh you know there'll be talk about climate change and the health of the planet there'll be a lot of rock and
roll and fun too so and we have some surprises that will be announced a little bit later so we hope that you'll
be able to come and there'll be future stases of course but you know the trick with Garett the director and founder is
that you know it has to get bigger and better every time and some pulls this off you know it's remarkable so we hope
we'll see you there somebody uh with the moniker of Fender 90 uh is watching on
YouTube and he says I concur last armas was a surreal experience so with a name
like Fender 90 I think this is probably a a musician watching so whoever you are
it's not Brian because Brian ised Vox amps yeah
so yeah okay all right well that's very cool all right so um we will move on uh
uh David I am going to let you um introduce Chuck
Allen uh is that is this David or the other David this David
okay yes there actually two Davids here tonight anyway this will be this David
David Shakespeare is going to introduce Chuck Allen I want to say something
about the astronomical League it is an organization that was
founded by harlo chapley and others over a hundred years
ago and uh to try to get a group of amateur star lovers not necessarily
amateur astronomers but amateur lovers of the night sky together and uh it started with
conferences that took place in the east coast and then um maybe 20 25 years ago
it finally migrated over to the West Coast getting organizations like our
local Tucson amateur astronomy Association involved and
uh it it still does the annual conference the one that will become held
this Summer that I will be attending will be in Kansas City and uh so Chuck
Allen is our representative from the league today and he is going to talk with us about the astronomical League
about things that it can offer things that it will inspire us to do and now I
would like to present is my deep honor to present Chuck Allen great get away Chuck thank you David um thank you for
those nice REM marks about the league and hello everyone um you the league is now 78 years old to be exact with 23,
23,000 members across the country and we're expanding into other countries as
well at this point so it's very healthy uh we've had a number of great quests to
the league and to its trust fund which has really helped a great deal um actually what I'm going to be talking
about tonight's a little bit different than that but if there's time at the end I I'll make some remarks about the
league uh at that point so let me share screen
here and GNA go
to from the beginning here we are okay uh what I want to talk about tonight is
the concept of Journey which is the subject of tonight's program and there are many ways to journey into the
universe and among those of course are man space travel and unmanned space
travel and also telescopic observation uh and back on December the
7th of uh 1972 I had the opportunity to
observe the third of the three Moon launches that uh I did witness in
Florida this was of course Apollo 17 and it was the final trip to the moon
uh December 7th 19 72 and aboard this particular flight was
Harrison Schmidt he was a scientist he was a geologist um I had the opportunity to
observe this from the VIP area from because of Senator John Sherman Cooper I had a couple of ins because I was an Air
Force officer and I had been he had been taught by my grandfather in college
anyway AA 17 featured this scientist who visited us at the astronomical leagues
convention in Albuquerque two years ago and this is one of the things that you can do not only at starmus but it also
at League conventions and that's meet some pretty interesting people uh this is one of the friendliest astronauts he
is in a story musra class of friendliness he will hang around as long as people want to talk to him or take
photographs with him and uh Dr Schmidt is is really a remarkable person
and he participated of course in the furthest man visit that we've made to
another world which is to our own Moon that's as far as we've managed to get but as far as that is it's not quite the
human altitude record amazingly enough the human altitude record in terms of human Journey was set by the ill- fated
Apollo 13 mission uh in 1970 two years before Apollo
17 uh LEL hay and swager of course could not land on the moon because of exploded
oxygen tank and the service module but they did Loop widely around the Moon which was near apy at the time uh and
reached a distance of 24925 miles from the earth and that
still holds the record as the furthest human beings have ever been from home uh
here 54 years later of course we're looking to go somewhere else we're hoping that we can
get to Mars at some point and how will we go there how will we make this journey to another planet uh it would
seem likely that we would fly straight out and intercept Mars as it comes around and reaches a point that's fairly
close to Earth it can get as close as roughly 34 million miles amazingly enough though that's not
how we'll do it Mars of course can be as far away as 250 million miles but the
journey we will take to Mars if we go will be 300 million miles long now
you're probably wondering why in the world don't we just take the short Route 34 million part of the reason is because
we have to first of all undo the 67,000 m per hour orbital speed of the Earth
around the Sun that's 2 and a half times the escape Velocity from the earth so
you'd need a vector that was in the opposite direction of the Earth in order to go straight out to Mars and that's
very difficult to do secondly in order to go straight out to Mars you'd have to
clim directly out of the Earth's gravity well and that takes a lot of energy also
we just don't have that kind of fuel capacity so what we'll do is this we will use the Earth's orbital speed kind
of track along with it carrying that speed right off the Launchpad and then just intercept Mars about halfway around
the sun it's a long journey but it's very fuel efficient takes about n months
it's called the H transfer orbit a home transfer orbit very
efficient of course unman spacecrafts have taken us
far far beyond all of this we've visited the moon with unman spacecraft uh even a
couple that are taking a nap on their side at the moment uh all of the planets
uh we have visited several asteroids and comets the moons of planets and dwarf
planets um and the takeaways from this
are that unmanned space travel is very efficient if you've ever seen images from the Cassini Mission uh it's spent
so much time around Saturn taking incredible views of the Rings of the surface of Saturn's Cloud tops and all
of its moons uh an incredible Mission Voyager 2 went to Neptune had passed by
Neptune 12 years after its launch in 1989 I remember watching the news reels
of this coming in when I was in New York for a meeting uh we got to see details
in the cloud tops of Neptune that we'd never seen before but again the journey took 12 years to get there that's now of
course the furthest planet from the sun among the major planets that we consider to be such it's companion spacecraft
Voyager one is currently the furthest man-made object from the earth
uh it now lies 15 billion miles from the earth uh that's roughly uh five times
further than Neptune uh is from the sun and it has taken now 47 years to get
there and it's traveling a little over 38,000 miles per hour so the question is
what if it were headed toward the nearest star to the Sun what if we wanted to send an unmanned spacecraft
like voer one at 38,000 miles hour in the direction of the nearest star to the
Sun proxim how long would it take to get there the answer is a bit more than
75,000 years and that's the nearest star of all the ones that we could possibly
visit amazing time frame in order to get there now I will tell you that it is
possible because of special relativity to travel great distances in fact if you
could develop a rocket that could achieve one G acceleration which is what you're feeling now sitting in your chair
and maintain that for a little more than one year uh drift for a while and then
decelerate for one year you could Traverse 4.2 Lighty years to Proxima centor in about 3.6 years of shipboard
time from the earth it would appear to take six years so it is possible the only problem with maintaining 1G Burns
for two years accelerating and then decelerating is that you'd need about 250 pounds of
fuel for every one pound of spacecraft that you put uh into launch for the the
star worse yet uh if you hit anything even sand grains going anywhere close to
the speed of light you're going to suffer fatal damage to the spacecraft and then you've got the problem of where
you end up stopping by the time you slow down you might find yourself nowhere near Proxima but uh relatively close to
it but relatively close is not really good enough when you're talking about space travel look how long it took to
get to Neptune which is a mere 3 billion miles away uh travel using this 1G method can
be visualized here as you can see Proxima would take about uh six years
viewed from Earth but it would be possible to go vastly greater distances within periods of 30 to 50 years using
this method but again is not from an engineering standpoint very practical
well what do we what do we see when we look at the Summer Sky from a dark sky location you
look toward the middle of our galaxy now you're really studying the universe with
human vision and with telescopes and what we see here is actually looking
toward the center of our galaxy from the Sun but we're really being blocked by
intermediate Galactic arms and we're seeing perhaps uh a lot of
these two arms right here as we look towards Sagittarius in the center of our galaxy and what you're actually seeing
here in terms of these star clouds you're looking at a distance of about 60 quadrillion miles about 20 million times
the distance to Neptune and you can do it with your eyes just take a look you
can also see this with your uned eyes on a reasonably good night if you knowwhere
to look in the constellation of Andromeda you can see our big sister Galaxy the Andromeda galaxy Messier 31
um it lies at two and a half million light years uh we're looking across a vast void here uh between the galaxies
in our local group of galaxies which consist of three principal galaxies the Milky Way on the lower right here
Andromeda in the upper left and little m33 which is to the upper right of
Andromeda I had an interesting experience with m33 when I was 8 years old I got frustrated
because I couldn't see it in the 3-in telescope I went to bed still frustrated
uh and then leaned out of a second floor window with a pair of binoculars and AED them straight up a triangulum and was
able to see it I slept like a baby after that as we look in the direction
primarily of Virgo coma barones or some major Leo um roughly in the springtime
Sky we see a lot of familiar galaxies like these and what we're why we're seeing so many bright and famous
galaxies in that direction this is the center of what we call the Virgo cluster
lying at a distance of about 65 million light years and what we're seeing when we look in this direction is we're
looking up kind of a conically shaped filament of galaxies here the Milky Way
is the Red Dot and we're looking at these famous galaxies I showed you and then the big Virgo cluster here and we
lie at the end of this filament and as we back away a little bit and look in the other direction we see M3 mgc 253
the sculpter Galaxy the silver coin which is here and we don't see many
galaxies in that direction because we're looking out into a void it's called the sculpture void predictably so here we
are here's Andromeda and here we work our way to the Vergo cluster this is
obviously a two-dimensional representation of something that needs to be displayed in three dimensions of
course but you're seeing now a realm of about 250 million light years and it's a
complex of Galaxy clusters called laka which means immeasurable heaven and if
we back away even further uh we begin to see our location in relation to even
more complex structures and Richard God who's been a friend of mine since I was 11 years old
and he was 12 uh when he was in high school discovered
a number of hitherto undiscovered pseudo polyhedrons and this led him to do
research later which he published uh and this Research into polyhedrons actually
led him and a compatriot Princeton into postulating and then proving that the
Universe had a spongelike structure think of Swiss cheese where you can eat your way through the cheese or fly
through all the holes all the way through the cheese and this led to the discovery of the cosmic web by the way he wrote a book
called The Cosmic web based on this and this Cosmic web is vast a vast network
of galaxies and Galaxy clusters that drapes its way through space if we back
away even further to 10 billion light years we would see a structure something like this now what can you do as
amateurs if you buy a telescope or you have access to the telescopes at a local
astronomy club well here's what the jwst the James web Space Telescope can do it
can identify this current record holding distant Galaxy called HD1 in the
constellation of sex the light from this Proto Galaxy which is now a
well-developed galaxy has taken 13.5 billion years to reach the cameras
that took this picture today because the universe has been expand the entire time
that light's been traveling to us HD1 lies at 33 billion long
years but don't fret because even small telescopes can do amazing things with a
mere 4in telescope on a real good night you could image 3c273 not image but see
in the telescope with your own eyes magnitude plus3 essentially and you'd be
looking at an object whose light quazar a bright active galactic nucleus whose light has been traveling to you for 2.4
billion light years and that's just a 4in telescope that can accomplish that
what can you do with an 8 to 10 inch telescope well there's another quazar in
Draco pg16 3476 it's very easy to find because of
this little pair of eight magnitude Stars here once you find it you just look for this triangle and then follow
the dots three 14th magnitude Stars a little Arc and this one right here well
that one the light has been traveling to you for 9.6 billion years when it
stops uh in your eye today it lies at nearly 13 billion Lightyear distance now
this distance is 5.6 sepon miles that's two trillion times further than Neptune
and you could see it with any ordinary small telescope that you would find in an astronomy club or perhaps in your own
BAS this is what you're seeing you're looking all the way across the cosmic
web Bas the light left there when it was here has taken 9.6 billion years to
reach us and it's now out here at 12.9 because the whole thing's been expanding since then but you can do even better
with a 18inch telescope maybe a 16 you can see APM 8279 5255 and linkx it's
another quazar another active G Galactic nucleus whose light has been traveling to you when you see it for over 12
billion years and that's in a universe that's only 13.8 billion years old today
it lies at 23.6 billion light years an incredible
distance what you are seeing is halfway to the edge of what we
call the observable universe which is the theoretical limit of objects location today that we could possibly
see today and 23 of the distance to HD1 which is imaged by the James web Space
Telescope rather incredible and if you're feeling small I've got a cure for
that one of my favorite little element samples here it's a cubic inch of tungsten heavy as heck and this little
cubic inch of tungsten happens to have 1.03 septi atoms just slightly more than
one septi that means 100 million atoms along one and that is well more than the total
number of stars in the entire observable universe and it's mostly empty space so
if you ever get the feeling small looking at space just get yourself a cub of tungsten and point to it say universe
thanks a lot Scott well thank you thank you so much
yes thank you so much chuck I I to say that I enjoyed that as an
understatement and as I was listening to what you had to say my own mind was going back to my own past when in
1977 I was visiting Arizona did have no idea that I'd be living here after a
while but we went out to um um Oregon pipe National monument and
uh while I was there I set up manura my 6-inch telescope which is now undergoing
a fix up and I was able visually to look
at the Galaxy at the quazar 3c273 it looks like just a star just a faint
star but it was absolutely Unforgettable I've never forgotten that and what was
also Unforgettable was during your lecture just now bringing me back to that
wonderful wonderful observing that I did all those years ago
thank you Chuck I'm thank you I appreciate it that's great okay all right so um we
will uh take it away to uh our next speaker uh Adrien Bradley who has
participated in many Global star parties now uh this is a guy perpetually in
search of uh Grand views of the Milky Way and nightscapes up kind kind of blow
our minds um Adrien uh came on to the last Global Star Party during a uh uh I
think he was at a bowling alley bowling his broadcast from bowling alleys from his car from from uh uh out where he was
doing photography and uh thank you for coming on to the 143rd Global Star Party
Adrien thank you for having me um Scott and as you can see I'm sitting stably
with a camera that actually see me I'm using my phone as a key light I'm always
trying different things and trying new things um that being a part of global
star party has been somewhat of a journey um from showing a few pictures
and and D you know your encouragement has um you you you continue to encourage
me to just continue following my passion and um I started out wanting to take
these great night sky photos and enter them into contests and you know see if
you know see if things go good there but um eventually I took it back to what
brought me to want to take images of the night sky in the first place and that was I love the night sky I love being
out there I started learning about the night sky as a visual astronomer I
learned from other visual astronomers aperture is King real dark skies are
important in order to see these things and then I said well I don't live in an area that has really really dark skies
and it's kind of hard sometimes to see things when there's clouds so as I'll
share a screen here I'm just going to share the entire desktop um so my journey takes me to
why I decided to start Imaging the night sky and
um I'll start with uh I'll go to one of my favorite galleries that I set up From
Dusk Till Dawn and do a real quick scan through because it's a uh as far as
journey goes this is where it all started and I know I've done presentations like this before um when I
do my presentations I try to encourage folks
to you know Chase your passion for Imaging I'm not as big a fan of Imaging
for money quote unquote although I have done some images that have been sold or
um you know have been published but this is where it all started with slightly
elongated Stars you can barely see the Milky Way this was a Canon 30d I think
that camera is 20 years old now and there is
Sagittarius and um let's see how quickly I can fast
forward um and we're going to just roll on down
to something I've taken recently and in a different
location let's go all the way to
okex the last time I was there
um we'll use this photo and so now here's that same Milky
Way with a little bit more detail this is this is an as you see it
image and you've got more detail more stars and
Sagittarius is hard to see but there it goes the
same same type of image and same um not the same camera using a
slightly different camera and if you can see here I'm trying to look at
m33 while this image is going on so I looked in that area of the night sky
um there is another picture I think that I have where I was able to take a
more so I was able to take one where I'm less of a ghost in that picture looking
directly at m33 with this refractor and this is where my journey
has taken me this is where this is where I am now still wanting to do visual
astronomy and see the night sky with my eyes even see deep Sky objects with my
own eyes but I still try and capture the beauty the Milky Way especially but I
will capture the beauty of other things such as maybe there's a storm
that's happens to be in and near the Milky Way and I can capture both at the
same time that was uh it was fun to capture or maybe I capture things that
aren't so great such as there's bright red there's a bright red light Over the
Horizon that's coming from an AT&T tower um man-made light pollution is something
I don't shy away from taking pictures of so when I go back um when I go back to
an area like Michigan and I try and take pictures of the same thing the light
pollution is visible and I don't edit it out because this is what the camera sees
this is what I see um we just had a wonderful um talk about seeing naked eye
this galaxy which happens to be the Andromeda galaxy and even in pictures
and even in places that may not be as dark you can still you can capture it
and m33 that elusive Galaxy um sit right here is a little
bitty glow and then there's another star cluster which I believe is NGC 752 so for me it's not just about
standing on a remote beach with Lake hon over here and a planet which I do
believe be Jupiter um and trees over here this is a
fa this is a favorite composition of mine it's a beautiful photo but there's other things such as a double cluster
and even the heart and soul there's dark nebula that are visible
and um all sorts of things there and here's in the Horizon even though
there's light pollution here in the Horizon you can still see the California rising and the ple is beginning to
glow and so as I began to hone in skills of um
doing night sky photography there were several things that I wanted to
accomplish and that is a beautiful place by day and doing bird photography and
then not being afraid to shoot the Sun during sunset um is a great way to spend
time other than if not just focusing on night sky photography maybe I'll I'll
practice something like panoramas here where you have this area and then you have the moon
rising and then make plans to come back now this this will go sort of in reverse
because I did take a panorama when it was dark in that same location and as I
flip through here I will find that and show you here is that Panorama and here
is that same area when the Milky Ways in the sky and when it's dark taken from slightly
different angle but there go those trees the area where you saw the bird
flying I like to take scenes at places that they're dark and take and not just
limit myself to astronomy pictures but um other pictures just showing what I
see this area Dark Sky Lodge and Tavern I took the picture
here and it's hanging in their um
it's hanging in this store now or in this restaurant so it's
um you know whatever angle here's a lighthouse but because of the
orientation of the Milky Way I decided to image it with the window of the
lighthouse this oil can and here's the Milky Way all in a row and this is the keepers
in the waters behind us and um here's uh here's the another Sunset
picture of that same place so my journey takes me as I scroll through these pictures what you're
seeing is how my journey just sort of takes me to different places and
accidentally capturing some amazing things um like this Aurora that was
facing due north and of course this truck which I no longer have because I
have now started a new Journey with a new vehicle I put 228,000
miles on that truck driving here and there A lot of times driving couple
hours away to take these beautiful pictures in the thumb and um and didn't
want to stop at jiz Milky Way Photography what can I do about the moon can I get some reasonably sharp images
of the moon and I wound up getting a pretty sharp image can I what happens if
I try and make it a mineral moon or do I need to really explode the colors or do
I make them subtle so that it would be yeah the moon's natural detail shows
but some of these colors show where the um you know where um Titanium is or
where rust is um where you these C's and
getting this sort of detail out of a 600 mm lens with these setting
and um noting these settings down because I've come back to these settings again and again handholding the camera
and getting these sort of results in the moon and balancing between artistic and just
testing things out this one was an award winner for rasque a couple of years ago
because it was in the light pollution category this is a farm area this is a
very bright Port here on more no um noise coming over here other parts of
Ontario um this is Lake hiron so Lake Erie um would be facing this way but
further south and there's more light pollution as well so the
journey becomes what is it that I want to show things like this image where how
much detail do we pay attention to there's the cats paaw and The Lobster Claw but this image wasn't
taken um down at you know the areas okit teex this is an hour away to the south
in a uh light lot of light pollution but still able to get this sort of
detail in a hazy night um from uh Lake Hudson dark sky Park in Michigan um how
much can I push the camera so that I can see the various nebula that are in this part of the
Milky Way there's a lot of dark nebula one's called the pipe I can't really picture it but I'm sure if I look close
enough I would see it you definitely see the Lagoon and you even see the
triffid M20 M8 if we back
out you see the shape of the Crazy Horse
these are the things that I that I think about when I'm doing my Imaging and um
some images maybe not so great other images the asabo river and this is one
of the few stacked images that I was able to get done and get done right there's even a little light pollution
here but some of this glowing some of this ha that you're seeing because I
stacked the photos a minute of exposure each and I stacked 10 of them seeing a lot more detail closer to
what I get with a single 4minute composite of the Milky Way out at Dark
Skies so you know so the journey has
been not only rewarding in that I've tried doing a few different types of
Photography that you're seeing here but it's also led to the next great quote
unquote idea what else do I want to do and things like this where the first
time I saw the Milky Way naked eye was in this location and I was looking up at
it a few years later I go back to take a picture and I do a two-minute composite
and to my surprise more detail of the Milky Way pops out than I thought would
show up but um and I didn't certainly didn't see this much detail here this is
a this is an approximate view of this were a bordal one site naked eye you would
absolutely see this without needing a camera but it it represents
my Fascination we'd call it Obsession but that sounds bad so we'll call it
Fascination um with Milky Way Photography and um so then because of
that my Aurora photography is thin I do catch it every once in a while I know
the Aurora really traps people's interest Moon photography traps people's
interest Milky Way Photography traps my interest and not
only the um Galactic core but the Orion
spur I try and capture detail like this to say well the Orion spur is actually a
very interesting place to capture uh Milky Way for photography it doesn't just end with this ginormous
core hanging out over here it is of course the brightest region
but sickness region when it's setting can be very
impressive the Orion part when it's when the zodiacal light is out can be very
impressive and you know I highly rep um recommend looking at that naked eye if
you're in a dark enough place um the core is bright and this of
course was so this says 121 seconds so back then I was doing two minute exposures of each so you have a
composite here that I was able to blend well enough two minutes to get the same
detail that it took 10 one minute stacks of images back
in my home state to get that level of detail of the Milky Way so dark skies
once again it comes full circle Dark Skies do matter but for different
reasons and that's because now when you're in a dark sky you see even more detail in the
area this is pereus is here cassieopia is up here and dram is here and there's
the Galaxy there's m33 again NGC 752
and even now if it comes in even with me doing some noise reduction on the image
this you know the galaxies come out all of this data shows up as we call it but
in the end you're looking at you're looking at an image and the Red Light
That You Don't See with your naked eye is reflecting from camp at okex where
all the red lights are on while people are um looking at their
instrumentation and you know using red flashlights trying not to disturb their
night vision but there's so much of it that when you take the camera to it you actually detect that it
splashes all over the Rocks so so that really quick in a nutshell my
journey in photography I wanted to capture feelings things that
reflect and now this you know this picture is at a at a cottage of north
where at the time the owner the priest was alive um when I took the photo of course
that empty chair you know photography nuts would look at it and say get rid of
that empty chair clone it out but time passes on and now that priest is no
longer there so now I get to say in the photo this empty here is for the priest
that used to live there and um it represents that well he is gone but the
sky remains forever and as I continue my journey um there will be more challenges
more beautiful places more places to drive along um with the new car that I've got
and certainly more imaging even if it follows some of the
same um ideas you know it may just well it may
Inspire others to try and do the same thing it may continue to inspire me for
years to come and just like this little Rainbow moonbow that ha that I happen to catch
over Lake hiron you just going out in the night sky you never know what you
might get what you might find if you love photography give night sky
photography a try use longer exposures if you have a mirrorless camera look into the mirrorless camera
to see what you're getting composits are nice even shoot at the Sun
every once in a while as long as you have the appropriate cloud cover it acts as a filter and um don't be afraid to
shoot when the moon is out don't be afraid to shoot when there's light pollution
you know don't be afraid to try different things even if you're getting off of work um I took this picture with my
iPhone and then I think I turned around and I took pictures with my um with my
regular camera because I thought it was a beautiful color of sky and a chance to
take the picture light pollution was really bright but I still got a little bit of Milky Way over this oak tree
so there are a lot of opportunities to just say don't take a picture but for me
the opportunity to be out under the night sky you know and here here we are
Lake Hudson one of the earlier places where I did a lot of photography I still go out there I still make the journey to
all of these places to this cabin and um and so the journey continues um and as
you can tell the Milky Way itself makes a journey and maybe in another presentation because it's time for me to
hand it off um I'll talk about the journey that the Milky Way makes across
our skies but um as always I'm gonna end
with this particular photo and do with these two gentlemen you can hardly see
this is my friend Jim Forester over here that you can hardly see with the arrow
um now you can see him I see him and my friend and Nate Murphy um we go to okite Tech we were
watching the storms and I captured them as they watched the storms and captured
the Milky Way hiding behind here um you know it's a spectacular as beautiful as
the P thanks Scott as beautiful as this picture might be to you it was even more
beautiful to be there to experience it yeah so yeah don't I say don't uh
you know you can rely on photos or you can look at a photo op and say oh this will make a million dollars just capture
what you see see the photo then take the photo and
enjoy where you are even if it's not perfect it's still a memory and or an
opportunity to get better at presenting what you want to present to
others or you what you want to capture so that it helps you remember that night that was a pretty magical night with
that storm and it getting clear enough for the Milky Way to be visible on the other side so that was uh I leave you
all with this photo and yep it is time I think I've gone a little longer than my
time but uh I will pass it over to um our next presenter yep and um I'm
probably going to go and eat dinner but thank you all once again for having having me on global star party and uh
here's to continuing that Journey um you looking at the night sky
taking photos discovering new things trying things that seem impossible and
never being discouraged If You by Cloud conditions Sky
conditions um just keep trying try some different things and see what you can come up with excellent
excellent yeah I I knew that DAV would want to comment on some of these because
isn't his his night sky photography it just gets better and better yeah I I not only does it get
better and better but I now like to think of Adrien as the ano atoms of
astrophotography is High Praise High very good yeah I I do intend to continue
pushing my own boundaries I I know some great astrophotographers um I know some folks
who you know they they do a certain they do the Imaging a certain way I do
appreciate their work and some might be watching Global star party right now
however my own take is the night sky without the night sky there what would
we be Imaging we've got a great AST imager I see you on um Ron without the
rosette nebula what would you take a picture of and without the universe you
know what could we do we would have to turn and continue to do bird photography
because there wouldn't be a universe to see because we can see that Universe we're able to capture bring those
photons down we're able to bring the photon of the veil that you've got behind you and share with the public
this is real it's not you know fake photos I heard something Dave Scott
about fake photos and I say you know so it's
um if the object does exist and we're bringing it out it's a real photo it's
you know it's just how we bring that object out now if you take the moon and
you make it appear as though it's sitting on top of the Washington Monument and the Moon is bigger than the
Washington Monument there may be some questions you can ask but um you know I
tend to go for exact what I'm seeing so it's all up to interpretation but these
things are very real and definitely want and we are I consider myself a space
journalist so I capture where what I see and I try and present it not too
overly you know image not too light either you know to where you can't see
those structures what a cool idea that is space journalist that's space journalist yeah be a bed journalist
don't be a you know is this real um you know you say yes I was there
I could take you to the place and I usually try to take two types of photos before I turn it over to you I take two
types of photos one how my eyes see it I actually try and make the photo look the
way my eyes see it the other I try and bring out some of the structures that are sitting there rosette in the Orion
side of the Milky Way or M M8 you know in the galactic core or the um North
American sitting in signis or um all the stuff and Andromeda and m33 I try and
make sure those are visible when you're looking at the casapia and perus Wing So
in the northern hemisphere I've still got two more sections to go I got to get to the southern hemisphere to see the
melenic clouds and the uh krux Southern Cross region those get those that'll be
a special Global Star Party when I can get to those that's so uh all right
great let's move on Atri thank you y thank you all for having me okay well we
have uh uh we're happy to bring on yet another very talented
astrophotographer I like this kind of astrophotography segment that's going on right now uh but uh uh Ron breacher
surprises me and and I'm sure blows away all of his friends uh with his postings
of his latest deep Sky Works um and uh but you have quite a journey yourself uh
Ron and so uh we're going to turn it over to you to let you describe it okay
thanks for having me on um I will uh let me share my screen and uh then we'll go
from there one second all right let's go to the
slideshow come on now there we go so you know
whenever whenever I get an invitation to a global Star Party the first thing I do
is two or three times maybe read over the the theme of the star party which
Scott always includes when he invites us what the theme of The Next Star party is
and um here's the important parts of the theme that I read this time as we gaze
at the night sky we not just observers we're participants in an ongoing Cosmic
drama and it's an Ever evolving journey of exploration and inspiration and that
that kind of made me reflect on my own journey and uh you know every astronomer
I know and I love I love to talk to people at Star parties and so on every astronomer I know has what I call a
creation story you know there was a point in time at which we weren't
astronomers and something happened maybe more than one thing happened and now
we're astronomers and uh it's really fun sometimes to hear people's story I'm
going to uh hope that you'll indulge me while I quickly tell you my story and uh
so for for my journey talk I going to talk about my own creation story tell you what I'm doing now and uh talk about
what's next and uh part of my cre ation story as you're going to hear is this book Night Watch by Terence Dickinson
and um I think my very first edition of Night Watch was the first or second edition I don't still have that because
I keep giving this book away to new astronomers uh so many people started
with this book uh but let's come back to that in a minute and after I tell you what I'm doing now I'm going to
speculate on uh what might be next for me and uh it's all just musing so uh
this is this is Gail and our dog sweetie standing with me in front of my
Observatory my happy place the best man cave ever and um this is part of my
creation story too I guess because um this was a 50th birthday present to me
from Gail and uh so although it wasn't right at the beginning of my journey it
completely changed my journey and um I really want to acknowledge Gail you'll
see here how she plays quite an important role in all of this so my creation journey is really kind of like
a stool with three legs um the house the family and Night Watch so let me tell
you about each of those so in 1997 Gail was pregnant with our uh second child
who you're going to meet in just a minute and um we needed a bigger house
and this is the house that we bought we bought a house in the country and our first night in the house was on New
Year's Eve uh 1997 going into 1998 and with the house came a new bank
and a new mortgage and a new credit card and the old Bank contacted me and said
well you've got all these Visa points before we close out all your accounts when we settle up your mortgage is there
anything that you would like with your Visa points and I got got a toy train I
had a son at this time my son Todd was uh three years old or so so I got a toy
train uh something for the kitchen and what I thought was a toy
telescope but it wasn't a toy telescope it was a 4 and a half inch reflector on a wooden Mount uh an equatorial Mount uh
and so that's the first leg of the stool I was able to get outside with that telescope and um I saw the Moon that
kind of blew ble me away and I saw Saturn but everything was pretty Rick rickety enter her family this is my
daughter Chelsea I said you're were going to meet her in a minute she wasn't always this beautiful and in particular
this quiet when she was a baby she was kiy and she used to scream all
night and um our new house had a big long driveway and it was out in the
country where it was dark and quiet and I used to put Chelsea over my arm and
walk her up and down the driveway in my bathrobe and work boots walking up and
down with her in the call of c and she's going to sleep and I'm getting more and more hooked on the
sky well then at Christmas that year so now it's 1998 December
1998 my business partner gave me this book Night Watch and I ate it for
breakfast I read it from beginning to end really quickly and um I was particularly struck by
chapter 4 I looked for this but I don't have a copy of the original anymore
because I've given them all away uh but chapter 4 was called choosing and using a telescope and there was a sidebar
article called Junk Scopes from Asia and it had a picture of my
telescope on it that's when I realized uh that that
rickety uh that wobbly Moon and fuzzy Saturn and fuzzy Jupiter that that
wasn't really me being a bad astronomer it was that my equipment wasn't really up to task and I got a Bonus a couple of
weeks later my first bonus uh one of my first bonuses since starting my own
company and um I used it to buy a real telescope it was an Ultima 2000 and now
here we are so that was about WR 1999 1998 99 and here we are now 25
years later so uh let's quickly look at this trajectory I thought you'd be
interested to see the background here it's my log my observing log and I'm not
going to go through all of this stuff with you um but I do want to talk a little bit about logging and sketching
and a little bit about the story of the Genesis of my website um so log and sketching I said
the the background here is a couple of pages out of my log and I did a a
handwritten log every time I observed for about nine or 10
years and I also included sketches this is my first
sketch it's it's the Blue Snowball nebula and I was looking at it I was at
a star party and I was up the ladder of my 20in and when I look at it now it
just looks like a fried egg but you know we all have to start somewhere and that was literally my very
first sketch now I got better at sketching but I pretty quickly moved on
to astrophotography and um I want to just tell you a little bit about where astrod
do came from um I didn't come up with astrod do at all it was my wife Gail
that came up with astrod do and it wasn't until 2013 so I'd already been at this for a while and she gave me some
vanity license plates for my car uh and there's the license plate
right there I didn't actually launch my website which is called astrod
do.a until about five months later so it was Gail that came up with that moniker
and uh since launching the website in April 2014 I've had more than 350 50,000
page views so thank you very very much for for looking at that I uh it makes me
feel good when people look at my pictures and I know um you know the when you post something on Facebook
compression makes it so that you don't really get a great view of the picture you don't see it the way I want you to
see it so if you see one of my posts click on the photo and uh see it the way
I want you to see it um this is the website it's astrod
talk.c and um one of the things that I do is that with every post I post all of
my uh processing details so that kind of helps people learn a little bit I I love
to teach okay so what am I doing now well I'm producing images I'm producing lots
of images um and I do that mainly for fun um as as Adrien mentioned uh it's a
different thing if you're going out shooting pictures for money uh I I could I certainly sell my
pictures I sell a lot of pictures but I'm shooting them for myself and a lot of the pictures I sell I shot years and
years ago um I shoot them for myself there's just nothing like it for me than
getting out there and I I should mention you know a lot of times when I'm Imaging when it's not cold out I get my visual T
scope out I am still a DieHard visual imager and regularly have people over to
look through my my 20-in obsession and I have a homemade 10-in job that I love
um so I said uh producing images this is one of my images and it's on the cover
of the newest version of Night Watch so talk about full circle um I started everything started
for me with night watch and now my own photo of m42 is on the cover of the
latest edition and such an honor Terrence Dickinson um he died before the
book was actually released but I know um I learned that this was one of his
favorite shots of this region and that he was involved in choosing it and uh
boy what what an honor that is I love to demo equipment and the latest thing I'm
demoing is this gigantic 14inch Edge HD
I'll show you a photo at the end of the Pres presentation that's a work in progress that I'm uh that I'm capturing
with this really big telescope and I love to teach um some of you might know
that with Warren Keller uh he's he was my mentor and teacher in asro
photography but now he's my partner along with Pete PR and we started uh this this website
called masters of pix insight and we do workshops once or twice a month on image
process processing and also there subscription stuff but there is a ton of
free content there so if you get a chance check it out it's Masters ofix
insight.com and of course I love to write um I I
remember it was around uh it was around 25 2015 or
2016 when my very first photo got P or first um article got published in sky
telescope and um you know astronomy magazine sky and Telescope BBC sky at
night I've been reading these magazines since the late 1990s um they have been an inspiration
to me and the thought that I could now write for one of these magazines uh and even have my photo on
the cover this is my my first uh Sky Andel magazine cover what an honor um
such an honor I I can't tell you so yeah that's what what I'm doing right now and
totally totally loving it so what do I want to do in the future well I want to
see a total eclipse of the sun I've never seen one I've come close a couple
of times um where I live we're going to get
99.4% but that's partial so I have a couple of places
within a two to three hour drive that can get me into the path of totality on
the day of the eclipse so hopefully I can take this one off my bucket list I really want to look through some big
telescopes when I say big I mean like big professional telescopes um I got to
see Mount Palomar from a distance when I was in California I've got a friend who
works at kit Peak so come on guys I want to look through one of your big telescopes I want to be able to image
these Southern sky but I'm willing to wait because I really like being
Hands-On with my equipment but when when I don't feel like operating my own equipment anymore or I move away or the
light pollution just gets too bad then I'm going to get some time on some
equipment in the southern sky and uh you know I've been I've been talking about
publishing a book of my images based on my website content all the content is there it might be called something like
postcards from space except uh you know that's all still up in the air but I
think all the content like I say it's right on my website already and um
starmus so um starus is on my bucket list of places to go and there's a bunch
of reasons for that number one is I can be a great stunt double for Brian May if
he ever needs an astronomy stunt double or even possibly a guitar double although he's away way better guitar
player than me second of all one of the founders of starmus Sir Harry Coto
Professor sir Harry croto was one of my supervisors on my PhD committee and I
used to babysit for one of his kids so uh there's all kinds of reasons why I
want to get to staris one of these days I think it would uh just be a hoot so that's my
goals and um you know my wife always reminds me that I can do really anything that I set my to the sky is the limit
and uh this is in my very near future this is about three and a half hours
only on mesier 82 I'm going to be acquiring a total of
about 20 hours and um I'm I think I'm up to about uh 12 or 13 now I'm Imaging as
we speak so thank you for indulging me I hope one day we sit down and I get to
hear your creation story because they're all fun thanks Scott wonderful wonderful
great great presentation so okay um we
have uh uh Caesar brolo up next uh down in
Argentina um but um let me
uh let me bye for now put my how are you put up my my uh iPad here
since I had that also connected here but um um uh Ron I I really appreciate all
the work that you do and uh uh all the help that you give to uh people that
want to take that Voyage Through astrophotography uh you've really got to be changing some lives uh uh for the
better so it's uh it's so much fun it's a privilege yeah it very cool thank you
you all right see you next time okay next timeon okay so um our next speaker is
Cesar brolo and Cesar is um uh as I mentioned down in Argentina he works for
opticus srao uh and is a telescope retailer but
he's also an optician he's made his own telescopes I believe that uh he and his
father actually built observatories and he is a well known individual in
Argentina in the uh amateur Astro uh astronomy scene uh he loves showing
people how they can get into astronomy even from their own backyard or from
their balconies and uh so I'm not sure how he set up tonight but uh let's bring
him on yes fortunately I don't have uh CLS In This
Moment oh clear sky yes I am the in the rooftop of the the buing it's
a 27 meters high here um is is more clear
is more affordable and great to to make
some uh uh as Astro pictures asro photos
and I'll show you I'll share my scre ring and a live image of oron because
last last um in the last start party was impossible to show show you something
because I remember that they have like a big rainbow of reflection between the
buildings and now I have to show you um
much better quality I have some problems here uh because one of my accessories
connecting the camera with the telescope have a border not black and this uh
produce a an small small uh reflection
but despite this I clear now this and we are going
to St uh some pictures live of oron nebula
despite this this reflection we can H will in live a an stacking of uh of of
your nebula picture and in few seconds we can have some
details that in the single pictures we can see for
example let me try it's
possible for example it start to appear this area of this dark
nebula that cover this part of of the of the
nebula the the bright part of the
nebula and um two I I took h a picture of tarantula
nebula ear here um uh well while we having uh this uh
stack uh live stack of oron nebula we I can show you uh
how I have the tarantula nebula let me
check if I can yes I uh um I opening
another application and as soon as possible I share I change the the sharing of the
screen I'm going to to open another
program I'm
changing I can see you in the your
office okay share the screen we are going to see is I know see
okay I try Scott to process something something very
short of the
picture that they took and
here oh I don't know if
this ah this is an Oreo nebula of today but no I need another
this and we can check how is is
going how is cooking the oron nebula in
our in our uh captures
now we return to the other nebula live
stack you can see more details
maybe is the the nebula now have three
minutes near to four minutes of
exposure and we can have a a a a gray picture to
process but and we are uh stucking live now and this is maybe is not so good to
make a picture ofion but it's great for a show where we can for us or
or we can share this kind of of tools like a
livestock is great to show in Show
like now or with friends or sharing details that maybe in a city or the
colors of a nebula we can we can
uh we can't see the details of of the
different colors and here we have more details now that
earlier and we can get more details I uh
while the nebula is increasing in details because we are stacking and
stacking pictures one over another one I return to try to show
you they took that uh ah okay okay I understand my
[Music]
okay for today is is sure that we are going to to see look that
when I started to to make the the sorry the name the
exposion I don't have these details of oring the idea we have now six minutes of
exposure and the idea is going to have this shape that we
know neula and uh we are having more and
more detail this is new this is new because it's uh product
of stacking pictures and pictures as sometimes I don't like use the live
stack for only for make a picture but it's a great it's a great
tool for this that I tell you that for show in a live
image um the the
the the mo the how is increasing the life in a nebula in a in a cluster um
details now for example we can have more clearly the difference between the
mesier qu 43 and mesier 42 and if if I still
talking why is it's like you know it's like a cake in the in the oven it's something
like a we can see how it's ining and the shape of the Nebula look that we have
now 7 Minutes 41 seconds 46 and this is
something that many many times what we say that is so magic so magic that we can
make this kind of image Oran is a is a easy nebula and I encouraging to the
people start to ear on in the field of nebulas because it's a nebula for South
and North emere is the the brightest nebula in the in the sky and is the the
door is the door to to to take
confidence to make more and more image of the sky especially deep
Sky um it's it's something like uh well if
we H having um having a a time to make a a better
picture and this picture we can uh do it much further because we can
process uh it's really great really great I have I have uh while while um
it's work to see the same pictures and while I still talking about another
thing I have you I have sorry I have a small very small
presentation uh from my WhatsApp from my
phone sharing while the oron is cooking in the
oven I'll show you some pictures that they have hi
Marcelo hello yes there we
go I like your
shirt okay okay so this is your setup Yes actually this is the the the
the setup I sit here
so is that a tablet H I use I use a
my my phone to to drive the the exos 100 here is my my living room because I
I I start watching the the show this is the part of David ier from my living
room this was today with the the ac90
explor scientific that many many times I put in the street uh and take some
pictures of the Sun and with with the very easy because
I use the the cell phone and I encourage the people especially the kids this is
the telescope that I so more for kids and it's a great great um
telescope because it's easy uh to to find the image with the cell phone
adapter um look the it's a
meal in the in the front of the my store of my
store and this is the picture that I took today of the sun with a single
filter solar filter safe solar filter and today we we see we watch uh
uh at one this one is to don't easy to
to see the another Sunspot uh but four
four SS in the yes in a line in a line yes and this a big one that's a really
big one and we are preparing this Friday a encounter in in our in our
friends Staff San Miguel
Observatory well this was my my picture of oron H last week H Scott while we was
talking I say oh was impossible no no was impossible of course that is not the
perfect picture but look that in the in the middle of the of the city I have m42
M m42 m43 this part of the nebula that is
amazing that I I could between two weldings um was very very interesting to
to to have something well let's
return let's go and return to see how is
the now the or your NE look
that we have more more details
maybe it's fun how how we can uh we can
have something great where we um starting to
um very very dark image and now we have more and more details actually we have
more than two minutes of exposure and we can go and have more
more uh details and this is now the the the live
image of of I can try I can try go to
um another another maybe takar maybe I
don't know if I have my goto precisely but I can we can we can try we
can try well I change first of all I close Liv
[Music] stack
now I am I am in the a really
live single four you can see how how I I can I can
show you how I move in the telescope it's totally
real it's not artificial intelligence nothing it's a telescope with a camera
with a M and uh well I'll I'll choose kle
nebula maybe we are
going without prise something special I try to make a a a picture of Karina a
live picture I don't know maybe I'll go go into the the same area and I I prepare for you next week
uh the picture of a tarantula that I
took the telescope is
going something that we can see in is
that that it's so bright so
bright for your name let
me put stronger G okay this area is really
full full of star and I check if I can
Center in because I I need to say
that this technique is is very easy it's only changes funtion to
to to
now well it's too much
gain there you go okay yeah it is a little more yes yes that's
cool look that area is so strong
and if you have this kind of trouble me now that my goto is not
precise align
it I can try no
problem I see only the the Define there because I have more
more [Music] field I Center in
this it's looking good
now Caesar do you take um do you invite guests to come up and see this setup um
uh when you're doing this kind of Imaging do you show people how easy it
is yes maybe you can you can you can see you can listen the the noise of the
motors actually I can't I cannot hear it it's too yes is it's
quiet we are we are uh traveling this is like like a
vage yes Star Trek I I'm curious Caesar do you bring do you bring people to see
uh to visit your uh balcony astronomy uh
uh do you ever have guest over or customers come yes in the
Rooftop in the rooftop yes because when somebody live in this area
yes sure oh I see a globular cluster yes this this cluster yeah
Jesus I love the because I there it is of all yes put a a
velocity lower velocity which cluster yeah yeah we are which which
cluster is this I think that this the the name it's really I think that this
the the cluster near to the nebula I don't remember if maybe maybe
55 67 my memory sorry but it's is in the
area okay we
can it's a it's an open cluster very very interesting it's beautiful though
yeah beautiful beautiful pile of diamonds you know
poured out
nice
beautiful
question look that very nice
class maybe each star is with no more no
more right like maybe nine magnitude
even know very nice and if you if you
see the the color of the cluster is more with more R red stars like another ones
very interesting
I put less game to have more contrast but it's very fine this cluster
it's open but I'm not sure that this the cluster that I
say because we can try with live stack okay
here less with less
gain now we have a better a better
image but I don't I don't sure which cluster
is because we are in the area but it's something that I can't see in the
totally is blind this to my my
finding totally it's something that is impossible to see in this area in this area I remember
I be having remember my the shape because it's it's very particular the
shape um I need to know who is who exactly
is try if I
have remember that all of this is is live yeah can be
fair
and what's happening now we we are in the in where we are in
the in the area of of Karina okay
yes but well no it's it's too much for
for tonight it's is an area full full of of
a star but but
my maybe maybe uh yes I try I try if I I
can open the the um this another one this uh
Tanta nebula me one minute more because it's the
time I don't know how many minutes I tried this
but
well we are returning to
serial okay
I think that yes okay yes yes
yeah Tanta neula from today let me show you oh my God
sorry you can see and I'll I'll try to stretch a little
more
okay
okay
okay out look that of course that it's it's a um this
is the nebula and of course that is not the best uh way to make a picture in
this way of live stacking and this is because we have a lot of Art facts and
but you can have yes you can have a a image a live image in minutes and it's
so interesting neula maybe we can make
something um but well I don't try more
that I show you this because this was to was took earlier but I can make a a
decent picture for the next weeka but the idea is of
course uh you got the data you got the data there yes
yes absolutely and the nebula is very interesting because is a you can see a
smaller nebula than orona and maybe a darker not so right like oron but it's
I I don't remember how many times is more long a long distance that oron and
it's so big and and big tarantula nebula
that if you if you have at the same distance of a of the of your nebula
tarantula nebula you can have a a you never had a knife because it's it's so
bright and so big because a nebula that is in the in
the big magelan cloud is in another
galaxy in in in our accessory Galaxy this is very interesting uh sorry the
but the quality of of the of you know I don't remember how I can
show you with [Music] the like aumm of this but it's very
interesting really very interesting well this is all for for
tonight um okay sorry that fail a little my goto because I I I don't put the
the precisely the thetion but for for next week we can try
we can return to the to the rough tube um watch more more like in ah we can I I
stop the live stack of or sorry okay okay but good yes maybe we
can make a a a fast uh fast you know uh
process but I'm more I'm more interested and I say to the people use the camera
with the livestock because you can use a planetary cheaper camera and make image
of NE and this is very interesting well thank you Scott it's a
pleasure thank you very much Cesar and best regards to uh you and your entire
staff down there thank you so much thank you great by okay okay so our next uh
our next speaker is uh young Navin uh
Navin is um um uh living down in Texas these days
and and he was originally from uh um I think in the Virginia region uh he
joined an astronomy club at quite a young age and is stuck with astronomy the entire time and he's back uh now uh
talking to us about the history of exoplanet exploration and so navine uh
let me bring you on it's a pleasure to have you on global Star Party
there we go hello everyone hi Scott thanks for having me how are you doing how's
everything good how about you good I'm good yeah school is uh treating you well
and and uhh you're enjoying your studies so far yes school's been very
good here down here in Texas weather's been nice yeah Skies have been good and
so let's get into my presentation first so I'm G start my screen share uh let's
see just share my screen and let's go to the
presentation so can you guys see my screen yeah it looks good
okay so today we're gonna be talking about the uh great history of exop Planet
exploration and the first thing that we we're going to go and do is the first
event that happened in 1984 so this was the first planetary
disc that was observed and this is like an image of dust and
gas around the star known as B PCT Taurus and it was taken with the dup
Dupont 2.5 meter telescope in the Lost compas observatory in Chile in the sou
in the Southern Hemisphere and this is a 2.5 AR 25 arxan
exposure and this was back in April of 1984 and that's that's a while back and
our next event that we're going to go to is the first actual explanate that was
discovered is in January of 1992 and the two astronomers that discovered this was
Alexander wor Wan I'm sorry I can't say that like and
then American astronomer Dale frail announced the uh discovery of two rocky
planets in PSR B1
257 a plus 12 which is a pulsar in the constellation of Virgo and these rocky
planets are technically bombarded with radiation from like a dead neutron star that they orbit around which means that
these planets can't really support like organic life like humans or any sort of like other life life
technically and as we go into our third event which is the first exent found
around like a SE main sequence star which is in October of
1995 and the two astronomers that found this were D quos and Mikel
mayor which um they announced the discovery of the first planet orbiting
the sequin star known as pegas 51 and the planet technically for
reference is half the size of Jupiter and it technically just grazes
around the surface of like its primary sequence start and which is very interesting and
it's some something astronomers are still like wondering about and like researching about like recent days so
far and our next event is the first transiting exoplanet discovered using
the transiting method in 1999 and two research teams led by David
sharbono and Greg Henry um which were independently observed a planet orbiting
across the Star HD 209458 in the constellation of Pegasus
and this OBS observation allows astronomers to analyze the atmosphere of
the planet which contains water and oxygen actually which is similar to Earth because that makes a planet
habitable if it has liquid water and oxygen and this is actually like the
first planet found within the habitable zone which was found on April 14th
2011 and astronomers actually from Geneva University in Switzerland discovered this planet HD
28185 B and it is technically the same distance from the
Earth orbits from the Sun so technically us here in
Earth and the distance to the Sun and that planet is the same exact distance from its parent star and to that planet
and it orbits like the same distance from that star to that planet
which is similar to the Earth which is very um which is a coincidence it's very interesting and this planet for
reference is six times the size of Jupiter and let's go into our next event
and first light from first light from an actual exoplanet which is discovered in
March of 2005 and astronomers that discover a direct infrared light
observation from a exoplanet for the first time from planets HD
209458b and Tres one using the Spitzer t space telescope and this was one of the
first times that they actually used the spit Space Telescope for exoplanet um research and studying and this is like
this is going to start a new era of exoplanet exploration using
spectroscopy and infrared Technologies which is very cool and that's right now
in the 21st century right now which is very amazing and this is the first time that
astronomers were actually able to see a light aminating from a
exoplanet and let's go move on to our next event and this is the first map of
an exoplanet in May of 2007 and the same astronomer J David
chonu and another fellow astronomer Heather nutson used the spiter Space
Telescope again to create the first map of an exoplanet and this is very interesting because mapping out
exoplanets is kind of a tough thing and Spitzer is is very crucial and it's
going to play a huge role like this study of exoplanets and the next event as we go
on to is first exoplanets observed using
spectroscopy and this is eight planets HD
29458 B and HD 189733b are the first planets to their Spectra observed by the
Spitzer Space Telescope and these readings provide information about each
planet's atmosphere which again it's very interesting you can see like type of atmosphere they have like what like
the type of gases they have whether they have an ozone layer or not which is very interesting in general and that's
something that will play into find finding many more exit plants in the
future and next event now we're we're going to use the Kepler space telescope and Kepler
contributed to a lot in like this uh field of exoplanet exploration and it
comes with many crucial interesting discoveries
which will help contribute to find ex planet and n and the Kepler's
first Bak exop planet is called Kepler 10B and it is for reference it is 1.4
times the sinus of Earth and this is an image of that planet how it would look like and and this was in January of
2011 and next event and this is the first exoplanet
cloud map created which is in September of 2013 and this is using data from the
Spitzer t space telescope which astronomers create the first exoplanet
cloud map and this is cloud mapping a planet which is 50 times 50% larger than
the Jupiter called Kepler 7B this is an image of that planet being um Cloud
mapped and next to and then this is the first earth size planet found H in
habitable zone in April 2014 and this is similar to Earth because it's it's the similar size to
Earth and it's Earth sized also and it's got the similar climate the Earth and
stuff and it's called it was the first bird size
exoplanet where liquid water could exist was called Kepler
186f and it was just 10% larger than the earth and 500 light years away not that
far it's fairly close to us it's a similar Earth not too far from us which is which is
very insane and yeah and Kepler again after that
discovers hers bigger older cousin in July of 2015 and Earth's
bigger older cousin is known as Kepler 452 has made its debut to the public in
the earth to us and the size of this planet is around 1.6 times larger than
the earth and has a claim of only having 385 days to orbit which is similar to
our 365 days that Earth takes to orbit the Sun but it's com its nickname is
super because it's the bigger older gigantic cousin of her and next one and this is technically
the Clos exoplanet known to men right now and this is discovered in August of
2016 and this is a rocky planet that is discovered near the star of Proxima centari and this new planet is called
Proxima B and this would orbit a start that would allow liquid water to form on
Surface and we we don't exactly know if this planet has liquid water on its surface
but it's claimed that have liquid water on its surface and scientists are still doing research on whether this proximal
B Planet actually has liquid water and next one and actually something that's very
mouthwatering and crazy is that seven earth-sized planets found orbiting a red
dwarf star found in February of 2017 is NASA
discovers seven NS size planets orbiting a star called trapes one which is only
40 light years away and it's also in the habitable zone so seven of these earth-sized planets or Earth similar
sized Earth siiz planets and which are habitable would have liquid water maybe
which we don't know and but these are all seven habitable Earths which
is literally mindboggling which we which something we've never discovered before
and it's also closer to us also and officially on the planet
counter hits 4,000 exoplanets on June 14 2019 and NASA officially confirmed the
discovery of 4,000 exoplanets and na actually I think made this video on
mapping all 4,000 exoplanets and like this diagram here this is like an image of it and it's very it's a very cool
video so I recommend you guys to all see it it's a very cool video on all the
extra plants that are discovered and next one and right now
the current times near current times we're in the age of Discovery guys and
we've officially hit 5,000 exoplanets so far in March of 21 March according to
March 21 2022 and the count of exoplant hits 5 5,000 after 30 years of exploration
which represents a journey of exent exploration which this itself is a
journey 5,000 after 30 years and we're still going to keep going we don't see
any signs of stopping that's how sence is going right now
and before I wrap up I just want to show you guys a meme this is a very interesting meme
because it's a artist concept om nom nom nom it's a star e Planet world and this
is star called wasp 12b and this is something NASA released saying we're out
there and this is celebrating 20 years of exop blance actually this is a special
limited special meme match that NASA released
and yeah that's it thank you that's all I have for today okay all right that's
great okay having thank you so much it's uh
it's been a pleasure uh to have you back on to Global Star Party um I'm curious
that uh you seem to be very very interested in the exoplanet research uh do you uh do you hope to
participate in that professionally or maybe in a research project when you get to a
university maybe that's what my plan is but uh yeah I'm looking into like opportunities in like exoplanet like
research in like that field yeah and I might start like start in that field
like soon yeah soon okay well that's great well there's a lot of Citizen science
programs that of course you can get involved with uh Tess being one of them uh so um and I know that you have a
unistellar telescope and that yeah I'm aware of the unistellar citizen science I'm aware of yeah yeah and they they
they have have also detected been able to measure the dip and Stellar
brightness from a passing exoplanet have you been able to participate in any of
that so far not yet um I'm trying to get myself into it I'm I'm getting hooked up
into it and I'm learning I'm getting my way into it okay and I will get my way into it and that be make a
few all right well thanks so much n okay thank you for having me on the show yeah
thank you anytime of course you know so it's been a pleasure yeah okay hope to
see you guys soon excellent okay thanks so much all
right so let's see um our next speaker is marchelo Souza marelo is uh down in
Brazil um and uh he is the editor of uh
Sky Up Magazine uh which was launched originally by David Levy and Wendy Levy
and um it's great that marchello keeps the uh the magazine alive and uh with
lots of participants from around the world so this is a global magazine and it happens to be free so um and
marchello is also very much involved in uh astronomy Outreach the preservation
of Dark Skies down in Brazil I think leads the uh largest and most active
astronomy Outreach programs in South America so uh it's a pleasure to have
you back on marello you've been on many times and uh um how are things going in
uh in your part of the world thank you Scot for the invitation nice to see you
Dr David levie and the participants here every is a
great pleasure to be here here now the year began in Brazil because for us
the year only be only begin after Carnival then Carnival already finish
then say here in Brazil that year already began then now everything is
working here in Brazil this is something that is different from other placees in
the world but the year officially begins in January first
of January first but in reality only after Carnival that's everything begins
to to work here in Brazil let me I share my screen
here because I I I chose today to talk
about the James we telescope because I'm
studying the T the results of 10 and the work of the
telescope the because this year the topic of the Global Science oper will be
the James the James web telescope let me see if you work here
for me yeah this is a a draw
showing how that we need to be take care of the space around the
earth because you have so many satellites and space Jun
in that in few years I don't know what
to happen you have so many things around the op of the earth and but I I'm
showing this mze because I'm I will not talk in about satellites in of the Earth but
about James telescope and I show this am because only show the difference because
the James web telescope is a different he is
Notting the Earth like telescope I show this is difference
between the mirror of the Hubble and the M of the
James oh wow yeah it's it's that's a nice visualization right there yeah you
can compare with a person here and it is a big telescope that
the ER Cent space and something that is fantastic
this that I think that is the difference between as we already had other space
telescopes in different SS and but this H as it is a the
biggest Space Telescope many people now are trying to understand these POS these
positions in space that we also use to
have the space telescopes there the reason that you have space telescopes
that part of the rrad ultraviolet xrays gar
Rays the didn't arrive in the surface of the Earth whe that come from the Sun
from the space because H the atmosphere protect us then we need to
send telescopes to space to analyze the object in this wave
lens here another image showing difference parts of the infrared we can
see from the osphere this is the reason that we had a
project with Sophia that is a airplane that they used
to take pictures already send many space
telescopes I produ and Senter space got image from the GMA Rays until the uh
microwaves from space with many different kinds of telescope I have here
that shows more space telescopes that our
sent to space then having formations and different wavelengths in
different frequency then you now ER have conditions to to stud Universe
in all the frequencies and this was the Sophia that
I said in the the H the space but where is the
James these are five place in the solar
system that is called the lrange points
like range positions that are places where you can have synchronous movement
with the Earth the L1 L2 or have L3 L4 L5
and is a some of them you have the the the
forces the gravitation from the Sun and from the Earth you can have the same
condition for both then is a stable position and in other ones like L2 you
have the the gravitational force from the Sun and from the earth and both
allow that works like a centrifugal for a centripetal force and then
the the satellite2 can ER follow the
Earth in the or around the Sun then H James web is in position
L2 here is a image that shows this how that
the they have equilibrium between the the first gravitational force this a
potential gravitational potential and we had the others and yeah
yet have other space telescopes in other of these lrange positions one of the is
so that is L1 that
he we have image of the sun he but he is
orbiting in synchron in synchrony with the the Earth around the Sun in position
L1 that is located 1 million and 500,000 kilomet far from Earth the
same distance for the L2 approximately 1 million and 500,000
kilomet far from us but all the satellite the space telescopes they are
not in the L1 position they are
biting around dis position I have I amaz that you show but
I have another Space Telescope solar space telescopes that are the stum that they
have two different ER space telescopes one is
located the almost in the earth op but
behind the earth and the other ahead of the earth taking picture images of the
sun then you have the soul that is following the Earth in the around the
Sun and you have the St that one's located behind the other ahead of the
earth then have a daily image of the Sun from different
positions and I'm talking about this but we have others in L1 position and the L2
is now have the James we telescope that it's prob because we want to
see the space ER not in the direction of the sun
then ER they have a protect over that and the Mir ever is
located in a different not in the direction of the Sun in opposite in
opposite direction and this is this is position
of the2 where is located the James web
telescope there something fantastic what I don't know if for
everyone that studies astronomy that likees astronomy that something easy to
believe that the the humanity now has
condition to send the space ships to any position and put any Orit that they want
in the solar system for me is something ever that I analyze
this the loue of this Rockets the the
Journey of the spaceship until they arrive in the position is something
fantastic because you have different gravitational fields came from the sun
from the earth we now analyzing all the Sun and the Earth but we know that you
have effects from the other planets also but it's very difficult to to deal with
a problem with more than two BS and now we are considering three B
the Earth the Sun and the spaceship then something that's very
difficult to find a solution then it it shows how that we
the development of the technology the technology now something fantastic that
we can do this this another shows the position and
the or of the James web telescope telescope around
his position telescope didn't stay in
a in a fixed position they or fallowing the Earth around the Sun
but they have an illation around the that is that you call this L uh
Point [Music] position and these are two image that
shows the importance of the jamesb telescope that is changing many things
the the left image is the the image of ultra
deep Sky image from the hble telescope and the in the right we have the same
vision in a image from the James W telescope we can see the difference
between both here
uh a mosa that has made joining both images from the Hub
and from the James web telescope this is our DP
Sky something fantastic amaz we have fantastic
results that's this is the ring NAA from
the Hubble telescope and now the same one Frontier
James W telescope yeah we have different
wavelength that you analyze but uh you can compare
both now this shows that we have
fantastic data to analyze we got ma of objects at three 13
billion and 5 5,000 million
years ago is almost is very is not so
far from the period that you begin we consider that happen the big
bang and is a reasion that we didn't imagine that we find
structures then I think that yeah when we have
Fant better telescopes we got receive data that can be
H make us to change the models that we have that we consider then as happened
in the past maybe we are now leaving a moment that probably we make discoveries
that that will make us to consider a
different model or make changes in the models that
we consider like the big bang let wait to see and now I have a
new information I read this today I think that today that you has
announced now Uranus now has 28 moons and Neptune 6
moons three moons for Uranus to to Neptune each day we have
news news we have a new discoveries and new information now H the moons of only
around that is the planets this is the final until today now I don't know
tomorrow but today these are the data that have H has 95
mooves no moons now sat 46 moons uran 28 Moes and Neptune 16
mooves now we having so many moons now wow 146 moons around Saturn yes most of
then are small moons very small moons but is the planet is the planets is it
amazing they're like solar systems unto themselves each one it's really
beautiful every if I was reading a book about the solar system from five years
ago everything is different about the solar
system everything is changing very [Music] have each day having new discoveries new
informations new data then this shows
that the technology that we now have and
have control of technological resources that we allow us in few years
to have a unbelievable equipments like the telescopes the
digital telescope that you have now that are very small digital telescopes that give fantastic allow us
to have fantastic M and I think
that in few years we have everything for us will
change but develop activities because
you need new equipments and need I I I I was talking
today with a friend about this uh in the
a few years ago it's we go with telescope everybody would like to see in
the IPS the maze but now all the kids
have smartphones have tablets C the maze here
and these telescopes allow them to see the maze in their smartphones I don't
know if this generation now if they have the opportunity to use the smartphones
to get the maze if they feel motivated to go
outside to be with your to look in the I of the of telescope I don't know what to
happen I don't know what to happen and I I I I can I can follow from my
daughters if they have a smartphone or a tablet for for them it's
fantastic I this I was remember what happened with our friends a group of
friends that organize observation this happened more than 10 years
ago they was observing a lunar eclipse but they had a telescope scope
with a simulation of of the eclipse animation one person arrived and
stay all the time looking for the simulation of the eclipse they didn't look to the sky see
the moon no she saw only the simulation the computer then he left thank you
thanks then and left 10 years ago this something that make me to think
about our future what we need to do I think that
this H soon everybody will be discussing this
in the astronomy events we cannot avoid this discussion
because things are changing the digital telescopes each day
are less expensive then it would be possible for everyone
buy considering the technology that they have you know so um we uh we were at the
winter star party with uh with this telescope uh which is it is about
$22,000 but we were able to live broadcast um uh images of the Oran
nebula and we were having 20 and 30 m an hour wind gusts in in on the beach and
it was still able to give us nice images of Orion and uh even uh Jupiter you
could see the cloud belts on Jupiter and this kind of thing so um you know and
when you use something like this uh and also get involved in their citizen science programs and stuff uh it's quite
powerful you know so uh um you know the integration of computers and software
and imagery and all the rest of the stuff is allowing people to to uh
explore things in ways that they never dream that they could do so but um but
you know it is disappointing to think that somebody would just look at software versus looking up at the real
Sky you know so yeah I I prefer to look the sky to have a manual
telescope no electricity nothing David David Levy would also
agree with this he looks at the night sky every clear night
so what do you think David I absolutely would totally agree with Marcello and uh
um I'm not much of an astrophotographer and that's something some saying something considering that I've taken
thousands and thousands of Astro photographs when I was observing with the
shoemakers but I'm primarily a visual Observer but uh I love doing that and I
love I love the process of going out under the night sky and looking up and
marello you did a brilliant job tonight thank you yeah thank you thank you very
much it's nice to see the Journey of uh where we've come so far and uh we can
only imagine you know as you say what is what is the next only five years or next
year going to bring us you know uh we have so many uh discoveries happening it
seems like every week or almost every day and um it is a great time to be
involved in astronomy if you're watching this show and you're just thinking about
getting involved in amateur astronomy uh I can recommend no other uh lifestyle
than this because it is filled with amazing people uh of the best character
and uh uh doing some of the most interesting things you can possibly imagine so yeah
y a little bit of of business Scotty sure U because sometimes you're hard to
reach sometimes you're not but uh next week I will be there I will be here but
I won't be able to stay P much past my poetical thing because I'll be in San
Diego sure but but I will be there for the beginning of it if we have one next week all right well that's fine that's
right just want to let you know Y and marello uh uh I mentioned you're already
starting on the next edition of Sky Up Magazine um you know if you're listening
out there and you'd like to submit photos or articles or whatever you know
uh marchello would be very happy to uh receive those and uh you know
consideration submission in the magazine so uh I write an article there David
Levy does uh marello does but also there are writers from around the world
participating in this so uh if you haven't got the most recent issue of
Skies up you can just go to explor scientific.com skyup
and uh we would be uh very pleased to have you read our latest issue um that's
available right now so and contributions will be very welcome
yes is is fantastic to know what people are doing around
you we have so many groups that are developing fantastic projects right and
the magazine is is a a space for they
show what they are doing for our that's right contribution will be
very welcome well excellent well I think this is a wrap uh thank you so much to the
audience thanks to our presenters thank you David Levy uh for uh co-hosting uh
this program with me and um uh it's a definite highlight I look forward to all
week long so I honor to be with you Scott y same same all right um let's uh
let's take this away and um I
will good night marello thank you good and to the audience thanks we
have an international audience watching right now and uh uh you know all the way
from the UAE to South America and uh uh Europe and of course here in the United
States and North America South America so anyways uh take care and we will be
back with more Global Star
Party
