Mapping One Billion Stars In The Milky Way And Beyond

[distractionxx]

great vid ★★★★★

[alliemunsch]

Excellent page here..loving the vibe!..



[enoughzenough]

This still doesn't change the fact that we Europeans are paying shitloads more money for Celestron and Meade telescopes than the US and Canadians do. When I happen to think that Schmidt, Cassegrain and Chrétien were all Europeans apart from Ritchey. I'm sickened just by the thought that we pay twice the pice for these telescopes! Our governments don't want us to become educated or what! We do have the technology but not for the grand public? Why are telescopes so f...g expensive in Europe?

[jr2261999]

wait

how can they get a map of our galaxy but not know whats on neptune

FAIL!

[mhobot]

ok, we will have a starmap around 2020, now all we need to focus on is how we gonna get to the new found planets !

[lokoxxxxx]

i love science but cant watch this video because of her

[jvictorthegreat]

GUYS, have you tried the Transcribed Audio function. Click on the CC button and have a laugh.

[jvictorthegreat]

No matter what they say about her gestures. I would marry her all the same.

[dkrypto911]

a little too much hand motion imo

awesome video though :) can't wait for Google Milky Way lol

[natman48]

you can tell she uses a mac, she moves her hands way too much.

[uut0]

doesnt milkyway@home also calculate this?

[irodmann]

Can't wait to see that 3D map of our galaxy in 2020.

[hochdaddy]

0:27 pause. lol. i'd still marry this woman. <3

[slimdXi]

@hochdaddy pause at ANY moment - it's all good!

(try 1:30)

thnks for a new hobby.. lol

[lurdk]

Does anyone else get a sort of William Shatner vibe from the way she speaks?

[KaelHunter]

She's getting better her voice isn't so annoying anymore but I still think she's a robot...

[LAnonHubbard]

Very interesting.

[kyledavidbyron]

What three bastards marked this thumbs down? lol

[Nickodemusodurn]

@kyledavidbyron

I was just thinking that!!!

[brmadman4455]

I can't tell, is she talking to me? 

I keeed, I keeeed, this is a great video, as usual.

[kobidobidog]

All of this is showing us how small, and insignificant humans really are, and how big the creator of all of this really is. This same God can be in each and everyone of us to help us to be good to whoever preparing whoever to go home with him where he is, and have the grandest adventure one could possibly; imagine.

[216trixie]

@kobidobidog Is this the Bible god? If so, no thanks. He makes Hitler look like Mother Teresa.

[kobidobidog]

@216trixie You don't know God. The idolatrous Established organized religions are teaching you the god of baal who demands human sacrifices.Why we have war,and condemning humans. I know the real Loving God, and I can teach you if you will have the patience to let me teach you,and to show you the error of the the E,O,R God takes no pleasure in the death of anyone ,and wants to save the soul of as many as he can. Don't turn your heart away from him by being bad to your neighbor.

[co0za]

hate to say it but 1 billion aint enough

[ButterflyDragon9]

I was totally distracted wondering how that woman can concentrate with hair in her eyes all the time.

[meatnug]

i want to smack her for the way she keeps moving her right hand.

[SillyCyban]

lol, judging by most of these comments, space exploration doesn't interest these people; only mating.

[grimwatcher]

holy fuck that telescope is gonna accumulate 1000 terabytes of info.

1000 Terabytes!

[sorry8140]

@grimwatcher i think they call 1000 terabytes an exopbyte. but ya, holy shit, where the fuck do we store that much info?

[SourcesAreEverything]

3:20 Looking at those flags really shows that space exploration is bringing the world together. GO CANADA! :-)

[yamaguchiyo]

amy mainzer, please replace this boring woman!

[aminizakoyayim]

Rebecca Barnes is the hottest woman on the internet. I'm so in love!

[rationalmuscle]

@aminizakoyayim A little chunky for my taste, but sexy eyes and great set of... attributes.

[Boy192]

@rationalmuscle Sexy eyes? She's f#%@ cross-eyed!

[rationalmuscle]

@Boy192 Yeah, that bit was a joke. ; )

[DarthCelcius]

@aminizakoyayim search google for "porn2 then come back and comment.

[maksphoto78]

@aminizakoyayim Then you haven't seen Amy Mainzer.

[m00ph00]

i want to just tie her arms to her sides so she stops moving them while she talks.

[leejw00t354]

Why are her trousers so wide?

[DarthCelcius]

@leejw00t354  fat arse?

[Wolfmoon23]

@leejw00t354

she has an Ph.D in Hip Hop

[Akshayphadke]

is that British accent?

[tonybeir]

shes is so hot. I would devote my life to her

[Kougeki1000]

@tonybeir get a life

[tonybeir]

@Kougeki1000

i do have a life but the great majority of women you meet are not smart and can't carry a conversation about anything scientific. In fact they actively dislike "smart talk" "it's boring"

[DarthCelcius]

@tonybeir myleene klass

[oggleman]

@tonybeir she's alright. doable for sure but i'm not digging the gay looking haircut. my astronomy crush is solar astronomer holly gilbert, ever since i saw "the universe" episode 101. if you're into astronomy chicks you should listen to astronomy cast, dr. pamela gay is an amazingly intelligent person, and she has a sexy voice too

[BFDK]

I love when our wealth of knowledge blossoms to more than before

[mattghtpa]

Every time I watch videos such as this one or recently a more profound one that covered the Hubble Ultra Deep Field View it amuses and saddens me at how advanced our science is getting, yet science is still handicapped by humanities reluctance to accept that not only is the Universe a place of wondrous astrological events, but also likely a very biologically active place with diversity exponentially matching Earth flora&fauna as well socio-civilization(s) aspect.

[Paxmax]

I wonder if Rebecca is used do presentations besides a boring whiteboard? She engages/occupies the audience with rather large hand movements which is a bit distracting wen there is animations running right besides her!

When there is generic background it's more ok to use big body language.

Still Rebecca, fantastic job!

[luckystrke]

Go Rebecca! <3 you're the best

[niiidar]

I didn't even know this was happening! Very interesting project, I have always wanted to know how the milky way looks...

[JonThm]

There can have been no Big Bang

[popgrafix]

REBECCA! STOP MOVING YOUR HANDS!

[EmperorAtahualpa]

Science rocks! Suck on it, religion!!!

[szlamx]

I feel like a child again.

[jmaxwell2]

She Blinded ME with SCIENCE!

[1imax111]

science #ftw

[saxmanchiro]

Love Science, dislike dogma based on imaginary friends.

[acs1978aus]

What a fascinating project. Lovely presenter as well!

[Rode57]

#GOOD

[dangermous1968]

It's about time....I'm outta here! now where can I download it to my Tom Tom? #LOL

[bangNL94]

Seriously, I have so much respect for everyone involved in this project.

[myjizzureye]

1:30 mark, just what exactly is astrometry..... here I was thinking it was astronomy. Wow she sure made me look like a retard huh. Certainly doesn't look like a fat chick reading a prompter trying to make out its clever. The massive billowing baggy pants might cover up your massive ass but the fat roll thats jiggling around your guts is a little harder to disguise (^.o)

[legionkreinak]

@myjizzureye

Lol, Google.

[Direkin]

@myjizzureye Astrometry is a branch of astronomy which focuses on the measurement of positions and movements of celestial bodies; the data collected is then used in other branches of astronomy.

[myjizzureye]

Hello, im Rebecca Barns, and im a dumpy fat chick with a boys haircut.

[fornss]

@myjizzureye If that is fat to you, you must be anorexic.

[brianl9944]

I like this charming lady... and like her accent as well.

[newcoleco]

Question : if Gaia need to be as stable as possible, how it will deals with "solar winds"?

[MegaYippie]

@newcoleco

Solar winds are generally quite weak - they move at rather high velocity (some 200-2000 km/s) but the particle density (in the order of tens of p/cm3) is usually way to low to have any mechanical influence (friction/slowing down/move the satellite).

The L2 point is gravitationally quite stable (three-body stable) and that's the point of using it. Of course corrections over time due to other gravitational sources are needed.

[MegaYippie]

@newcoleco

Oh, if you didn't know, since I failed to specify it clearly, the solar wind is always present and omni-directional of the sun. It just varies over time due to how the sun behaves at the moment. That said, it's quite stable over a short enough time period.

Basically, protect your electronics from the ionized particles and fix the orbit with small rocket engines if your satellite is moved by the wind, atmosphere (low orbits) or gravitational waves (mountains/other planets etc. etc.).

[Danandria]

Well, I'm glad Europe is going to do things like this.  Obama has basically killed NASA, I guess that's his "change." No, I'm not bitter, sure.

No, I honestly find Gaia to be a good step forward.

[MegaYippie]

@Danandria

Obama saved NASA. The Constellation project was sort of the scrapyard project you'd expect as cheap entertainment, instead of something done properly with new technology.

That said, Gaia seems cool. And, yeah, let's make sure Europe gets its own space program! Doing the calculations, if each EU country coughed up 200 million Euros a year for 20 years - we could have our own Apollo program running for that time. Call your representative and make it happen!

[Danandria]

@MegaYippie Yeah, 200 mil a year I think is doable...as long as Greece and Portugal don't pull things down. I liked the Constellation, because it was based on the Saturn V, something we know worked very well. True is was built last back in the 70's, but Obama wants to privatize Space....and I don't see that happening because a real space program is not profitable even with all the new tech developed solving the problems.

[MegaYippie]

@Danandria

The standard type of mission, unloading satellite and parts and crew for the ISS, is possible for private companies. I mean the kind of boring mission that is more of a business transaction than space exploration.

Let NASA deal with what's fun instead. Why waste the time of some of the most brilliant people in the world on trivial things like space stations and close-orbit satellites? NASA should work on the future manned mission to Mars or the establishment of a permanent moon base!

[Danandria]

@MegaYippie Precisely! That was what Constellation was going to do, but it's dead now. There was over a billion spent on that program already and it was all wasted. Now, there is no plan for US manned space flight....I just can't help but think: WTF!!!! The US is going o have to depend on Russia?!?!

[MegaYippie]

@Danandria

But Constellation was a failure. A complete waste of time. It couldn't even make it to Mars. The money spent on the project was dead money from the beginning. It basically was a scam and it is good that it's gone. Why waste time on scrapyard technology when you could develop better things?

Read Buzz Aldrin's take on Constellation: "Why We Need Better Rockets". It describes my point better than I can do right now (give me some years though(...)).

[teemuruskeepaa]

Could you please make a new Celestia with that catalogue?

[Direkin]

@teemuruskeepaa Probably add it as a package, but by the time the survey has completed there probably will be a new Celestia anyway :)

[DeathBringer9000]

why does every scientific video have design vs no design jabbering on it?

[LordNapalm]

I still say I would do her... like, if shes into it I mean.

Also.. great video.

[BlueNile123]

@LordNapalm hehe, yeah great vid. you sound as if you were once hesitant on the doing her part. she's doable...lol. peace

[LordNapalm]

@BlueNile123 I just noticed a lot of people saying bad things about her in previous videos. Thought I would throw in my 2 cents :P

[kyebean]

isn't this channel called "BestOfScience"? since when is astronomy the only science? what about biology, physics, geology, etc.? There's arguably more interesting and certainly more immediate news in other sciences.

[kyebean]

wow ms Barnes, we can speak english you know, but you get an A++++++++ for body language effort. that's practically sign language.

[216trixie]

Her hands are as big as the Milky Way.

[aminizakoyayim]

i want to marry rebecca barnes!

[jsmythib]

This is the BEST youtube channel ever! and ...a great hostess! :) Gaia is also, extremely cool!

[igytsiycm]

Great coverage of GAIA! I luvz u guyz =]

[andyct1982]

stop the video at 0:58-0:59 frame it slowly

[jsmythib]

@andyct1982 Ya know I had to go and look lol..COME ON!!...good one tho haha

[andyct1982]

@jsmythib thats not the only one either. lol

[BADBOYCH]

I have always wondered what our home galaxy looked like. Gaia looks like it might me able to chart every object within our own solar system as well as every other object within the Milky Way. 1 blillion suns charted so far. Another 399 billion to go.

[DancingHorses26]

Ok, so what I got from this is that we don't actually have a picture of what our galaxy looks like, because we're inside it looking out. I never really thought about that before, but it makes sense. So then when I Google "Milky Way", and get pictures of galaxies from the outside looking in, those are just "artists renderings" I guess.

[igytsiycm]

@DancingHorses26 Yes, because no object that could take pictures has ever left the galaxy from Earth.

[gordon1201]

Wow, a galactic map! Paving the way for space travel.

[nishbrown]

Hurry up and map it already!!

[JohnDReiser]

I don't see the connection between the name they picked (Gaia) and the mission objectives.

[prabhatpalpal]

tits or gtfo......or science maybe!!

[CROUTONZZ]

Lets all watch science videos and judge them based on appearance.

[nishbrown]

@CROUTONZZ

LOL, That's the idea!

It's all in fun. ;-) Anyone watching this is obviously interested in Astronomy, and likely subscribed to this channel.

They almost make it too easy.

[HiAdrian]

Very interesting project, i hadn't heard it of as of yet.

[zx1011]

i wonder if she just mouths it or actually understands it

[theeyeisblind]

@zx1011

according to the awful dress she wore a few vids ago, i think she DOES understand because no model would wear such terrible clothes

[TheCaptainLulz]

@theeyeisblind no other model has a fucking PhD do they. Infact 99% of models have less than 99 braincells.

[beeqool]

look at 1.06 :D:D:D:D:D

[ProveItBro]

Science, FUCK YEAH!

[tsjoencinema]

3D map of the milky way. Very cool.

[Realjhad]

#OMG

[pokerslut530]

@Realjhad how did you do that?????

[Realjhad]

@pokerslut530 #LOL

[pokerslut530]

@Realjhad hahah i looked it up after I saw your comment :P

Google #FTW !

[gigantibyte]

Please correct me if I'm wrong, but since the light from stars take thousands and millions of years to get to us, they wont really be mapping where the stars are, but where they were.

[HKragh]

@gigantibyte Yeah, you are right. But they will be using the distance (and therefore how "old" the view is) to calculate where the stars are now...

[8DX]

@gigantibyte Of course. But it's all we've got, I guess.

[Kdajrocks]

i cant stop looking at boobs, what was she on about?

[IntricationZ]

@Kdajrocks you have weird taste.

[puncheex]

@Kdajrocks: Doctors can fix that, you know.

[FloppyFormatFrenzy]

I've always liked looking at old maps because it gives an idea of what people in that time thought their world looked like. Now we've mastered making maps of the world, we know have a good idea of how land masses look. It's neat to think that right now we're just beginning to chart the stars; it's like the first maps of earth, slowly we'll get an idea of where we are.

[gir908922]

Science FTW!

[jlmood2007]

#OMG

[okuma0kuma]

gaia is a good name

[puncheex]

@okuma0kuma: Why? The other observatories from ESA are named for astronomers. Gaia is the personification of the Earth as a goddess; more recently the center goddess of a new age religion worshiping the Earth itself as a being. What does that have to do with mapping the stars? I would have thought Bayer or Flamsteed would have been more appropriate.

[okuma0kuma]

@puncheex as in gaia hypothesis aka nature

as see gaia in space is the nature of the galaxy you not see irony of this !?

with out nature you and i would be as alive as moon dust it has nothing to do with religion

[puncheex]

@okuma0kuma: The gaia hypothesis is that the Earth is a living creature. I see no connection with mapping the stars in the galaxy. Oh, there is a a very general "wonder of it all" sort of smarmy connection that could "bind us all together"but beyond that? No, I don't. Sorry, nature to me is the action of evolution over time and its results, combined with hydro-, litho- and atmo-sphere effects. I don't personify nature; it is harsh enough without willing its actions.

[GodKillerAtheist]

@puncheex "a new age religion worshiping the Earth itself as a being."

If you have a problem with religion you can always become an Atheist. Actually your comment is just nonsense. But I have to make fun of your bad logic. Take Care =)

[puncheex]

@GodKillerAtheist: Having looked it up, I find that gaia is a scientific hypothesis by James Lovelock and supported by Lynn Margulis, but opposed by Gould, Dawkins and others for lack of evidence. It has been adopted by new agers as a semi-religious doctrine, and to which they have added purposefulness (teleology).

Nonetheless, I don't get the point of your calling my comment nonsense. Where does Gaia have anything to do with mapping the stars, or where pointing that out is bad logic.

[GodKillerAtheist]

@puncheex "I don't get the point of your calling my comment nonsense"

I apologize I mistakenly took you for a new ager My bad.

[SiriusMined]

@TruthfulChristian

You keep resorting to the assumption that there is evidence of design. Your premise assumes it's conclusion.

Also, I'll correct your statement:

"Because the very definition of a design is to be caused and designed by A CAUSE that is uncaused because the infinite regression argument would restrict an infinite regression."

You are making the assumption that the cause is a being, with no basis for that assumption.

[Direkin]

@SiriusMined No, the corrected statement would read:

"I lack the understanding/education/intell­igence/curiosity* to know how nature works, therefore God did it". With that established, everything else is verbal diarrhoea.

* Delete as appropriate

[SiriusMined]

@Direkin

Well, I was feeling generous to TC.... his arguments are so bad, and he gets his face pounded in so frequently, I thought I'd show some compassion ;-)

Also, I figure the only way to teach him is to take him in small steps.....he's clearly not ready for the full answer.

[ScienceIsKnowledge]

@TruthfulChristian

Fuck off yo little fag. You are only here to provoke people. You care nothing for the truth, let alone science. Do us all a favor, fuck off back under that rock, from which u came.

[puncheex]

@TruthfulChristian: Causality is not a problem when you have quantum mechanics in the process; random, non-causal happenings are what QM does best. So, rather than going to an uncaused designer of the universe, we eliminate the middleman and go direct to an uncaused universe. Sorry, I reject your requirement.

[puncheex]

@TruthfulChristian: It would appear that you don't know very well your quantum mechanics (why would I need be surprised about that?). With QM, particles can come and go totally at random, with no cause and no prediction other than probabilistic. Rather than having an uncaused designer creating the universe, we have an uncaused universe. Your god? I don't need him, you can keep him.

[edeldoe]

@TruthfulChristian

I guess we know who the one downthumb is...

[okuma0kuma]

@puncheex haha pure nature and evolution are the same so you telling me mapping stars to find out clues to origin of life has nothing to do with evolution ? or did you just agree with me lol i think you did for once

gues this mean you confused my dialect again

when one species become extinct from event of a nature the food chain/cycle becomes unbalanced like a failing body organ ,example recent oil spill ,use any name you wish non of them can control nature if they could they would be gods lmao

[puncheex]

@okuma0kuma: Out in fairy tale land, evolution is whatever the user wants it to be. In science it is the study initiated by Darwins Origin of Species: the study of how biological species change, proliferate, and go extinct. It is not how life started (abiogenesis), or the Big Bang (cosmology) or Hitler/Stalin/Pol Pot's pipe dreams. Mapping stars is astrometry, as Barnes says.

When a species becomes extinct, it's not a problem but an opportunity for some other species to fill the empty niche.

[okuma0kuma]

@puncheex exactly evolution is only part of nature and gaia observer is now part of are galaxys nature ,barnes ego should stop looking only at land animals and know that once coral reef decay and die were will that opportunist be haha ,every one can be wrong just some of us are more right than others

[Pulsar89]

@puncheex

Gaia is an acronym for Global Astrometric Interferometer for Astrophysics, which was the original mission. Since then, the instrumentation design has changed, but the name remained.

[puncheex]

@Pulsar89: Ah, finally, a rationale for the name. Thank you. I appreciate it.

[smashbeans]

awsome!

[kroggwaff]

chicks talking about science is kinda hot.

[terr547]

@kroggwaff agreed :-)

[Arikiel]

I <3 Rebecca Barnes :D

The most interesting part of this in my opinion is finding out more about extrasolar planets. I wonder if they will use this to learn more about our outer planetoids in the Kuiper Belt and Scattered Disk.

[mobius1234]

Go Gaia!

[Bobbiethejean]

Oh Chripes, not her again. I want to TIE HER HANDS down. That notwithstanding, I like listening to her. :) Great vid.

[theeyeisblind]

alright! rebekah barnes keeps getting hotter with each vid!

of course the horrors of that ghastly beige skirt and leggings will haunt my mind for years to come...

[puncheex]

@theeyeisblind:

"Where did you get that dress, it's awful, and those shoes and that coat, jeeeeez!"

-- Johnny

[theeyeisblind]

@puncheex

yeah no kidding. just look back a few vids and she is wearing a god awful skirt that even a 50's nun would criticize

[GodKillerAtheist]

@theeyeisblind I think her husband dressed her. She's still cute.

[TheRationalizer]

Could someone explain something to me please?

Gravity pulls objects together, so why do photons effected by the gravity of the Sun make it look as though the stars are being pushed away from the Sun rather than being pulled towards it?

[Arikiel]

@TheRationalizer This is really hard to explain without pictures. The photons coming from behind the sun are at a slight angle to it and are pulled back toward it when they come around the side causing a bulge effect.

[TheRationalizer]

@Arikiel

Ah, I understand. I knew about that but until I tried to understand your answer I hadn't realised something.

It does pull the photons towards the Sun, but it makes it look further away from the Sun because our minds try to back-trace the photo in a straight line and think it came from a different angle (further out.)

Excellent, makes sense now, thanks for your time!

[superdau]

@TheRationalizer

Look up optics and how lenses works. Looking through a convex lense (at the right distance) makes an object appear bigger although the lense also focuses the light. This can't be explained without images though. So you have to search for it.

[puncheex]

@TheRationalizer: The photons on a direct path actually crash into the sun. Photons which are aimed at a slight angle away from the sun are bent by the sun towards the sun to then encounter your eye. So the star seems to move to the side, away from the center of the sun. As the center moves, you get the apparent motion. If you look carefully, the actual shape of the stars (or galaxies farther back) is bent and stretched and magnified as well.
