The Milky Way as You’ve Never Seen It Before – AMNH SciCafe

>>JACKIE FAHERTY: Is everybody excited? I’m just going to start with that. That’s good, because I can guarantee you
have never seen the Milky Way like you’re about to see it tonight. And it’s in part—that was a scream, I
like it. Whatever this energy is, I’m going to work
with it. What you’re going to see is rendering of
data that we do here at the American Museum of Natural History. And I’m so excited to show it to you because—I
mean, you guys are going to be some of the first people to see data in this way, rendered
in this kind of way because you are here in this place at the American Museum of Natural
History where we have some of the best data visualization tools. All right, so. To start, I want to set the landscape for
you. The landscape of astronomy. This is a picture of the nighttime sky, it’s
about the best kind of nighttime sky anybody on this Earth could hope to see. This is a picture of the nighttime sky. I was actually inside of one of those telescopes
when this picture was taken. This is a picture taken from the Las Campanas
Observatory, which is in northern Chile. And you’re seeing a fairly realistic, just
a little bit heightened, beautified image, of what the nighttime sky should really look
like. This is actually a very special picture. This was actually on my birthday a couple
of years ago. The photographer, Yuri Beletsky, took it for
me while I was observing. Notice there’s this red dot on the upper
right-hand side, I don’t know if you guys can notice that. It was a total lunar eclipse this night. So, actually—yeah, I like this. You guys, very nice, very nice, you’re into
it. On the left-hand side you’re seeing the
large and small Magellanic Clouds. You can tell it’s the southern hemisphere
if you’re seeing those two satellite galaxies of the Milky Way. And this picture, to me, I’ve got a giant
version of this up in my office. It’s one of my favorite pictures taken. And it is a gorgeous view. This is the view of the nighttime sky and
so when I ask all of you what you think of when you think of the cosmos, you probably
think of the nighttime sky. And you’d probably want to think of the
nighttime sky that I’ve got pictured for you here. However, and this is a beautiful image, you’re
missing some critical information here. The critical information that humans are just
not capable of detecting is how far away all this stuff is. Your eyes can’t tell that. You can’t tell that those two galaxies are
galaxies. That they’re not inside of the Milky Way
that we live in. You can’t tell that. You can’t tell what in this picture is the
closest star to you. You can’t see that. You actually need something else. You need science, which is real, not that
fake news, it’s real news. Well, with the applause on that. Science will give you answers to things like,
how far away is a star? And we’ve figured that out. The other thing that you don’t get from
this image, while magical and beautiful, is you can’t see motion in this image. All of these stars, everything that’s in
this picture right now, this snapshot taken on a gorgeous night during a total lunar eclipse
in Chile, is moving. But you’re not seeing it here. And what I get to show you tonight, through
the magic of data visualization tools and the magic of science, but it’s not magic,
‘cause it’s science, is—I’m going to show you how stars move. I’m going to take time and I’m going to
turn it on for you. And I’m going to show you how we can learn
a tremendous amount about our galaxy by looking at how far away stars are and how they move. So, I’ve got several movies that will take
us through that. And I want to thank a couple of things—this
talk was made possible by a couple of things. Number one, and the reason why I can do this
tonight, and I’m sure many of you actually don’t know this because it didn’t get
the kind of press I think it should have. That’s a satellite called Gaia. Gaia was launched several years ago. And on April 25th of this year, the entire
perception of the Milky Way was changed. The entire perception of astronomy was changed
on April 25th of this year. The foundation of astrophysics—the foundation
of everything you know about the cosmos—you need to know how far away something is. You need to know how far away a star is. It’s the foundation of stellar astrophysics. It’s the foundation of cosmology, it’s
the foundation of everything. And everything we knew until April 25th, 2018
of this year, was based on a prior mission—it’s one of the trivia questions, I don’t know
if anybody got it right—a mission called Hipparcos. There were 120,000 stars that Hipparcos had
measured distances from. And then we extrapolated on that and got a
ton of new information. Gaia came out on April 25th and released 1.7
billion parallaxes—distances to stars and motion. A hundred and twenty-thousand is what modern
astrophysics was based upon. One-point-seven billion is what we got on
April 25th. So that’s a big difference. You can applaud Gaia, because it is an amazing
mission. So, what I’m going to do for you is I’m
taking subsets of that Gaia data, and anytime you want to see Gaia, come to something we
do upstairs in the dome. I can fly you through 900 million stars. No one on this planet has seen that unless
you’ve seen it here, just FYI. The other thing, I’m using three pieces
of software throughout. You’ll note, I’ll have a little note on
the bottom of my screen during the movie so you can see which piece of software I’m
using. Some of this we develop here. Some of the movies you’ll see that it’s
me rendering them as I work through the science. But I’m going to take the Gaia dataset,
I’m going to break it down into subsets, and I’m going to explain to you how science
has moved forward using this amazing dataset with data visualization tools. So, I’m going to start with—I just showed
you the Milky Way. And there’s—this is going to be a movie
that I made using Partiview software, an open source piece of software. And this is a subset—so, 1.7 billion stars
breaks a laptop. So. Just in case you were wondering, it’s very
hard to render that on your laptop. So I’m going to show you subsets. This is going to be a couple hundred thousand
stars. A couple hundred thousand. It’s like me rolling my eyes at that—that’s
amazing. A couple hundred thousand stars. I’m going to run through this. So, this, now, is—this is not an image. These are all dots. These are all stars for which we’ve measured
the positions. And already you can see, before I start the
movie, it looks like the Milky Way already. I call this pointillism. It’s pointillism of the Milky Way galaxy. No one has ever been able to do this before. I’m going to turn this on and you’re going
to see—this is my flying around in the data. It’s a screenshot of me, using the software. And so the best part of this now is I can
fly out. I can actually move outside of the data. This is a specific subset of data. These are the hottest stars. So we never knew exactly how far away they
were because no one could actually measure their distances before, we didn’t actually
have a satellite that could do it. You can see I’m rendering this, I’m moving
out. So these are what are called the O and the
B stars that live hard, die fast. There’s like a—I mean, that’s literally
what happens. They are very big and they die in just a couple
million years. So they never move outside the plane of the
Milky Way. So, as I fly out, the dots that I turned on
there is the locations of what’s called “star formation regions.” Most people know Orion, right? Everybody loves Orion. Orion is the closest star-forming region to
the Earth. And so I pulled out, part of why I think this
phenomenal—notice these streaks. I kind of call them fingers of God. And those are marking for you clumps. These are where star-forming regions are located. And part of—I’m going to run it again—and
as you fall out, what you’ll see is, okay, we all know, that image of the galaxy you
just saw, we didn’t take that picture. Voyager is kind of the farthest thing we ever
sent and it’s barely left the solar system. So we’ve never taken a picture of the galaxy. But what we’re able to do in this map, and
as I fly out here the second time, what you’ll see is the locations of those star-forming
regions. Those locations of these hot, O and B stars
are telling you the shape of the Milky Way galaxy. It’s been heavily debated what the shape
of the Milky Way galaxy is. Does it have spiral arms? I mean, we think so, we’re in a spiral galaxy. What do those spiral arms look like? You can now use these stars as a map to try
and get to that structure. And part of why at this point in the video
that I’m sort of zooming around, and you’ll see I turn on this image of the galaxy and
turn it off. As you blink on and blink off, what you’re
seeing is gaps. And non-gaps. Which look like you’re basically getting
the structure of the spiral galaxy out from this very simple thing of just mapping the
hottest stars in the galaxy. Okay, next video I’m going to show you,
and this is my favorite one—you’re not supposed to have favorites, but I have favorites. So, this is my favorite one. This is what I call the solar neighborhood
flybys. This is something that I’ve wanted to do,
just something I’ve always wanted to do. If you know how stars are moving and you know
how far away they are, you can look at their trajectories. We are stuck in this static view, like I mentioned,
of what the galaxy looks like right now, what the nearby stars look like right now. But once Gaia showed up with all of these
motions and distances, we can turn time on and you can see—are these the stars that
have always been the closest stars to us? Did we ever have a flyby? Did another star come sweeping through our
solar system and knock a bunch of stuff around? Kicking comets and asteroids from the Kuyper
Belt and the Ort Cloud, the asteroid belt, in towards the inner solar system. Well, we can turn time on on this video. So this is a cartoon version of the sun. This is rendered with software we have here
called Open Space. So, again, in the corner here, it’s telling
you what software I’m rendering this with. And these are all stars that you cannot see
with your eye. Because your eye can’t really detect anything
but the brightest stars. And so I’m going to turn time on right now
and it’s going to go over a couple of million years. So you’re going to watch your future. And don’t be scared, but kind of be scared. This is a lot of stuff going on here. So, what you’re seeing—again, don’t
be scared, but be scared—that all of the stars around you are moving. Everything is moving. And you don’t know, though—are they moving
toward you? Are they moving away from you? What this video is showing is mostly—sorry—mostly
the stars motion through the galaxy. You’re watching the stars have their trajectory
in the plane of the galaxy. But notice some of them are flying closer
than others. And what was an immediate thing that came
out of this—this was actually something that we knew from Hipparcos, but we know it
so much better now, is that in—this another little movie that I’ll show you close in—in
1.2 million years, there’s a star called Gliese 710. It’s about 60% the mass of the sun. And it’s going to come within the Ort Cloud,
which is that cloud of debris that I’m flying you towards right now. You can see the star right there. You can come in past the glare of the sun,
past the Kuyper Belt into the Earth. And in 1.2 million years, look out. Who knows if we’ll still be around. But if are, Gliese 710 is doing a flyby. And, when it does, it looks like it’ll kick
around a bunch of stuff in the Ort Cloud. When it does that, it sends stuff into the
inner solar system. Now, okay, I’m not trying to scare you. But that is an absolutely important of understanding
solar systems, to know what is the dynamic nature of how things move. And just one other thing on this, too. I’m going to run this again. How many people have heard of Oumuamua? Anybody hear of Oumuamua? Couple of shouts, one or two. Oumuamua is this object that was a recent
visitor. So I’m just going to turn this on to continually
scare you. Oumuamua is this piece of debris, it looks
like, that came from a different solar system. It flew through our solar system very recently. It was discovered a year ago. And we caught it, it’s on what’s called
a hyperbolic orbit, which means it’s not bound to our own sun. Flew right out. Now, using the data like this, astronomers,
it was just last week, used this exact thing that I’m showing you to trace back where
Oumuamua might have come from. Now, we’re not sure that it’s right. I mean, that’s also the other aspect of
this. We’re not positive we got all the velocities
and the positions correct. But never before in time have we been able
to even take the step towards this. Where you could trace back the motion of an
object that came from a completely different solar system and try and find its host, to
find where it came from. An ejected piece of garbage from some other
star that just passed through here. And we studied it. And now we used this kind of thing to trace
back where it might have come from. So, that should excite you. That is the science on the horizon of what
we’re able to do in the nearby solar neighborhood. Another thing that we can do with this gigantic
dataset—this is something that I worked on heavily—is look for objects that move
together. Kind of looking for family members of stars. Until you know how far away they are and how
they move, you cannot know if they’re moving with each other or not. So what this movie is rendering for you, this
is a catalog of about 10,000 stars that I’m isolating for you. They’re very near to the sun. And I’m going to turn time on here and every
one of these objects is moving with something else. So you’re going to watch. This is over millions and millions of years. So the beauty of this is that you will never
get to see this, because we don’t live long enough. But I can simulate it for you. And so now, as you watch these dots, notice
how they’re moving in clumps. So you’ve caught a chunk of things over
here on the far left-hand side. Everybody’s got a partner here. And this, this is how you figure out where
do stars come from? How do stars evolve? How do they end up interacting with each other? Do they stay together? Are these clumps of just four and five stars—because
some of these are clumps of four and five stars that we’ve only recently discovered—are
they the last bits of core of a giant region of stars that had formed together millions
of years ago? Billions of years ago? This is the kind of stuff we get to figure
out now. It’s like forensic evidence that we didn’t
have before and all of a sudden we have access to. This is another one. This is now a catalogue, that was 10,000 stars
that I was focused on because they were all co-moving with each other. This now is a collection of stars that are
all young. So, we know that they’re young. All of these show the telltale signatures
of an object that is a young object. And so I’m going to pull out a little bit
and you’re going to see, there’s about 10,000 stars in here. And this I work on non-stop, because the young
stars near the sun are also where you would look for the baby solar systems, for the newly-forming
planets, for the areas where you’re going to get a glimpse of maybe what our solar system
looked like back when it was just a little baby. And as you pull out here, this is where it
gets intense, because you’re seeing what’s called the Centaurus-Lupus Super Complex. And as I’m saying that I’m forgetting
the full jargon for it. But this is a gigantic complex of young stars
near the sun. And I’m going to turn time on in the last
moment and you’ll watch that these objects—so these are the labels of some of them. There’s Coma Berenices, there’s Pleiades
8. There’s the Hades and the Pleiades, which
many of you might recognize because you’ve seen it in the sky. And now time is turned on and you’re seeing
how these things move. So they move together. But do they move together forever? That last video I showed you might be the
last remnants, the cores of these things which, at this point, we know are co-moving with
each other. They’re all young stars and this, this is
where the solar systems are forming. This is where astronomers look. And Gaia just gave us this unprecedented look
at where they came from, because you can actually run time backwards and forwards and see how
they interact with each other. One other thing that Gaia doesn’t do that
great of a job with, yet I was still able to pull out info and I have to say this because
this is my passion and my science, which is brown dwarfs. This is a video that’s showing you—even
there’s stuff that you can’t even see with your eyes in the Milky Way, yet it’s
right there, so brown dwarfs are these objects in-between stars and planets that are everywhere. And I just wanted to promote for you as well
that mapping the Milky Way and mapping the solar neighborhood is something that we’re
still doing today. The third and fourth closest—I said “systems,”
but it really means stars, star systems to the sun were only discovered in 2013 and 2014. Just imagine discovering an object that’s
sitting there right outside—it’s like turning over in bed and somebody’s there. And you’re, like, when you’d get there? Like, how did that happen? But that’s still happening. They’re really cold, so it’s also like
you can hide out because they’re cold. And I run a citizens science project called
Backyard Worlds,, if you’re interested. Go to the website. Help discover new worlds. Gaia isn’t as good with these because they’re
a bit too faint. What now I’m going to reflect on exoplanets. And this is a movie that we’ve rendered
here using Uniview software to give you a highlight of the current view of planets around
other stars. So this is a flight off of the surface of
the Earth into the nearby solar neighborhood, out of the glare of the solar system. And what you’re going to see is, as we move
out of our solar system, a bunch of stars are going to come up that we’ve only discovered
since basically the year 1995. But since 1995, we’ve been discovering exoplanets. And now all of the blue circles are showing
you were stars near the sun have been found to have an exoplanet around them. The majority of these that you’re seeing,
you can see that they’re all around you. And, as we pull out what you’re going to
see is a special catalogue of objects. It’s going to be color-coded in yellow and
it’s called the Kepler Planetary Objects. Kepler was this spacecraft launched many years
ago. So here comes Kepler into this field of view. Notice the blue circles here which are marking
for you the location of planets around stars. It’s very close to the sun. And that’s because a lot of those, we’re
just looking at the brightest stars using a technique called the radio velocity method. Kepler used what’s called the transiting
method, which means you stared at a field of view and you watched and waited for a planet
to cross in front of the star from your point of view. And so this is going to fly outside of the
Milky Way. Again, we didn’t take this picture of the
Milky Way because we’ve only gone as far as maybe outside the solar system. So this is an image of another galaxy that
we think looks like our own. And this should both absolutely amaze you
and also make you wonder, oh, my goodness, there’s a lot more to the galaxy for us
to try and figure out. So these objects we pull out, you can see
where Kepler was. This was our rendered view of it prior to
Gaia. I’m going to show you the view from Gaia
and part of that is Kepler redefined how we knew about exoplanets. Like I said, those exoplanets that you saw
with the blue circles, those were fairly close by. And, while we had a lot of them, we didn’t
quite have them the way that we do with Kepler. You can see that, you can go way further out. Way towards the edge of what you can do in
the galaxy. And there are now thousands of exoplanets
that have been discovered via Kepler. This is showing it to you now all mapped properly
with their distances from Gaia. And I’m going to turn time on in just a
minute and what you’re going to see it Kepler break apart. So this is the Kepler field of view. This is the view that you would have gotten
from Earth, from the detectors. And what you want to look for is, once you
have them all mapped out, you want to be able to see where they’re going and where they
came from. So, as we’re close in, you’ll see the
detector field of view comes in and we turn time on. And you’re going to watch where these stars
came from and where they’re going. That kind of broke the Internet when we put
this on Twitter the day after Gaia came out. So you’re watching where those stars came—where
are they going? Who are they moving with? These are all—this is the history of these
exoplanets. And this final thing that I’m gong to show
you is the thing that we can now with Gaia, matching it with very complicated missions
that now color-code all of these objects by their chemistry. So you can take very complicated surveys that
go and measure the abundances of different molecules and you can actually see, you can
see—this is showing you in color-coded—how much iron you’re getting out of stars. How much iron you were getting in Kepler and
then lots of other fields of view. And notice there’s the green and then it
gradients out to the blue. Blue means low metallicity. It means that there’s not a lot of metal
in that. That’s a signature of older stars, which
is what you see when you get outside of the galaxy. One more view of that from this perspective. And, by the way, the reason why this looks
so funny, with these footprints, these singular footprints, is because that’s the view that
we had from the telescope, when you looked up and you took an image of the sky. It’s in two dimensions and, through the
magic of data visualization, we can actually fly you through those datasets with Gaia Parallaxes
and beyond. All right. So that’s your quick tour of all of the
exciting aspects. I have probably a hundred more movies I could
show you, but I’m out of time on the movies, so I’m going to leave you with this takeaway:
The Milky Way galaxy, via Gaia, via many surveys on top of Gaia, is being mapped like never
before. And this data is revealing just the intricate
details of where stars come from and where they’re going. And, if you’re interested in playing with
the data, this is not just for astronomers. This is for the public. This is for everybody. This is for the kids. You guys are right here, I’m pointing at
you. This is for everybody to play with. So, download our software. Download the data. Play with it. It’s 1.7 billion stars, that’s too many
for the astronomers. There’s not enough astronomers for all of
the data. So please consider this your invitation to
the party of mapping the galaxy.

  1. Want more from Jackie on all things space? Check out our new explainer series, hosted by Jackie:

  2. Had to watch twice and could watch it again..alot of work went into this and ty for opening up our minds more.


  4. You're a great speaker, presenter, and SMART! Just like me….I wish. Like your video very much.

  5. Thanks Jackie… For telling the audience that there are five failed Stellar cores in our atmosphere chewing our planet to pieces … With more to come☹😲😢.

  6. Hollywood SPOILED US because this was NOT exciting. It's because the level of geniune scientific knowledge is nowhere close to depiction in science fiction.

  7. Magic! Amazing! Mind boggling!!
    And NOWHERE is a god detected!
    We are just dust in an unimaginable endless cloud!

  8. I am turning over in bed, and nobody is there, and it's still happening. Just imagine that one day, I don't want you to be afraid, but be afraid, if you could imagine, ahmna turn on time, and it is going to amaze you.

  9. Pretty cool but the shock and awe still seemed linear and presumptive in it’s presentation. The mere representation to the politicized Fake News comment takes away from the content and pushes it into the realms of climate-scientist’a and all the flawed and money driven results. Strange how nothing appeared to spiral in an orbit but float in direct paths with no apparent changes by gravitational forces of larger masses. Maybe just a precursor to more data and time to garner funds and grants or maybe the cosmic climate change science model OR maybe just a presentation that leads me to think 🤔- you choose – I have .

  10. If it's a scientific perspective it's a theory. If it's not a theory it's a religion. Take your pick.

  11. #flatearth NASA!
    F/NASA LIES ‼️
    EV' DAY
    ,.Nope, you need air to transmit the sound.
    ..Well, this proves the Astro'NOTS would die in min' from the heat.
    &. NO, we don't radiate heat

  12. Fantastic. I wish I would get the motivation to follow my dream career working like you do. But I don't and I probably won't. Damnit

  13. I'm 62 years old, born on Earth, well educated and you can put me down as a flat earther. But then this isn't 2000 years ago back in the Dark Ages when man thought the world was round we've come a long ways since then. Oh, I guess not. I guess according to science, science hasn't been wrong about anything in over 2000 years. Who needs GOD? We have NAZA.

  14. Happy indoctrination everyone!🎈🎈🎈🎋🎋🎋🎋🎊🎊🎊🎊🎉🎉🎉🎉🎉🎉🎉🎉🎉

  15. The earth will NOT TOTTER FOR EVER AND EVER .PSALM 104….you can worship NASA CORPORATION….OR GOD, We have free will, but government won't let us go to ANTARCTICA

  16. Bible warns against astrologers and stargazers….but you can worship FEDERAL CORPORATION if you choose, might as well worship CPS and IRS…the same corporate owners LIARS ALL, followed by will fully ignorant worshippers….

  17. Stars are light years far away from each other, so why on a clear starry night do stars look so close to one another as if clusters of stars were touching?

  18. Magic isn't sleight of hands, The demon magicians can make cards and other objects appear from nothing and also they can make objects disappear at the same time. That's because the real magicians are the demons, the magicians are just the mediums.
    The point I'm making is this. That by watching the demon magicians performing their small miracles, It gives us an insight on how God created the universe from nothing.
    God allows the demons to make objects appear from nothing before our very own eyes so to give us a clue how he created the universe from nothing.
    Magic isn't sleight of hands nor illusions, what you see is what it is.

  19. Why do you need to beautify your images??
    Oh I see, your interpreting data and then you produce what you think it looks like.

  20. Do you want beat you job or a 📅 soun wit a men the can help you find dark matter you can lose you job s in a mine at and you soul to or list in


  22. So why is she using CGI images just so called data show the real images from the so called satellites. She keep telling them i'm gonna show you a movie. Come on show real images.

  23. The video with the stars whirling about in every direction and coming into and out of eachothers does that fit with the big bang? Should all the stars be moving out and away from the singularity in a pretty stable rate?

  24. ThinK !  the stars she showed , looks like the organisms moving in a body of water, underneath a microscope…Bible says water above and water below…….Space is just a Fantasy made  up by so called scientist…..40 yrs of space and we have nothing but pictures…..CAN YOU SAY HOAX……I had a book of planets back  in the early 60's before we ever went to space, with great pictures……sure.

  25. I will tell you what to think and back it up with CGI, I will sell you what to believe with some hocus pocus, so that I will program your reality knowing that you will never verify any facts outside the box I put you in.

    When you speak the truth a child can understand. Where as if you speak a lie you have to complicate it so as to make yourself appear as an expert so that a thinking and a reasoning person will be swept away with what you say with out proofs.

    Wake up people and do some research. You would do that before you would buy a expensive item and yet you will sit there and listen to these preprogrammed sales pitch and invest your mind.

  26. Loved the video but there are so many questions I wish I knew the answers to, like Is there any symmetry in this new map of moving stars you have shown us? Is Gaia steadfast on 14 billion years as the birth of everything or are scientist willing to admit that the antiquated theory of the “Big Bang” is just not plausible anymore?

  27. Science is not NEWS. Science “explains” everything God has made.
    Nothing more, nothing less.

    Stop lying to children.

  28. so she sez ! im going to show you science ,, not fact news. and people go ha ha ha ,, she go's haha ,, and then eventualy she sez ,, well we'er not sure with all the numbers. and the room sez nothing! what a band presentation about guesses?

  29. Oh boy. I might have a case of pareidolia
    (seeing patterns in random data)
    And strangely after I point this out I’m curious if anyone else sees what I see.

    Stop video at time stamp 7:04 it’s just an image she says and not the real thing. But did you hear what she said before she played this?
    And I quote…

    ”This is me flying around in the data This is a screenshot of me using the software”

    So…it seems to be true that they really put the truth right in our faces by saying simple sentences.

    What I see is a sliver of her face that is upside down. Starting at the bottom is her forehead then an arched eyebrow, going up then I see a pc of her eye keep going up I see part of a nose then lip white teeth then another lip. These are all just pieces of each feature. So if you turn the screen just a tad to look at it the other way I see what looks like her. So when she said “this is a screenshot of me using the software”. Did she mean that literally? Like this is me that I made look like a galaxy, or what? If you stop the video at 3:50 take a look at her face and then divide it in half. Tell me that’s not her arched eyebrow or her lips and teeth.
    I don’t know why but this is what is very clear to me. Play the video from the 7:04 point and just watch that upside down image.

    Note: everyone sees things differently. So if you don’t see what I see that’s ok.
    And she might of possibly meant that is in fact a screenshot of her. I don’t know. It’s just pretty strange.

  30. Aliens and UFO are real.I think she would be amazed at how much we already know that she doesn’t know that they hide from us.The doesn’t say wow to me

  31. Finally i can see and understand what a telescope can actually do with today's technology, this is amazing👽🌠😱🤯🌏🌚

  32. ciencia esta ….puesta en un pedestal muchachita; ; la ciencia no le puede decir quien; ni como fuerton construidas las piramides; muchachita; ciencia; ciencia no puede llevarla de viaje a otras dimensiones; y visitar otros planetas en segundos mientras duerme; por favor; soberbia ciencia academica, entonces que es todo ese mapa estelar; virtual?; real?; fantasia?__ science is … put on a little pedestal; ; science can not tell you who; nor how the pyramids were built; little girl science; science can not take it on a journey to other dimensions; and visit other planets in seconds while you sleep; please; superb academic science_______________________where is the software to be downloaded….?

  33. Wow amazing can I get this in an app for my phone so if I want to take a look at another solar system I can access the app😍😎🧐

  34. Maybe we are all here as an eye witness to creation,space and everything around us,sort of a jump start to get us all thinking and to have ideas and inspiration,to dream,to wonder.I paint pictures on canvas and had a thought the other day if i would continue painting if there was none around to see and enjoy them.My answer is probably not….Why create if not to be admired. Wow,did i just make up a quote.

  35. Merveilleux . Merci beaucoup . Very easy to follow. Well … for a frenchie lol Well explained . Simple expressions . J ai ADORÉ . SIMPLY ADORED IT

  36. My curiosity didn't make it through the weird hyped type intro. More info less sell. Seems like this is being presented to people who are assumed to not know anything about astronomy. Shame.

  37. So we can see all this out side our solar system but we don't know what's all inside it ..whaaaaat T F ! Owe its Gia tv make sence

  38. Oumouamua a piece of garbage? Yeah right 🤔 didn’t know pieces of garbage travel a ridiculous speeds and take u turns totally against the realms of physics, please 🤦🏼‍♂️

  39. A piece of debris? Really? You are in the heart of space exploration and even you have been duped to think this isn’t a space craft- saddens me

  40. Interesting? At 12:49 you speak of the Oort Cloud as if it is a fact. It is pure theory and has never been observed. It is a theory because a rescue device was needed to explain why we see comets. You see, comets lose mass with each pass around our sun, hence the tail. Observational measurements show they can last no longer than 50,000 years maximum yet, there they are. We see them because the universe is NOT 13.5 billion years old and our solar system is NOT 4.5 billion years old. Plenty of GOOD science refutes this claim. Other than that, GREAT info video……..thanks!

  41. SHEEP … Science is SOOOOO far held back it's unbelievable. It's as much as mess as relgion as it is Patriotic.

  42. Several movies that are photoshopped oh yeah that's right it has to be LOL LOL data Photoshop just like NASA says all the time

  43. Wow, I'm watching an 8th grade reverse path tracking program (less complicated than auto return fire system for sniper bullet trajectory tracking )….

    Why's the program set data this guess was founded on?
    You say 'this and that' as facts…
    Though enthusiasm is appreciated however, starting from the false start of relativity this brilliant scientist is being stifled

  44. We don't get this type of info from our media because we accept a lot of the crazy, unimportant data they provide. In life we don't get what is fair, we get what we negotiate for. One important method of negotiation is to ignore the unimportant data and it's sponsors and, pay attention to the important information.

  45. Night time sky… We can not see motion in a photo…well I call it blur, that I can see, and know it is motion, but at what end of the perception. We learn we were wrong every ten years it seems.

  46. 🧐. Hummmm? Star forming regions? There has never been scientific observation of a star forming. No data has ever been collected of a star forming. You only assume or have been told that that’s what this must be.
    Again, assumptions and theories is not science.

  47. This is all propaganda. More brainwashing. Scientists discovered that the universe had a beginning. Also that the universe is expanding. Both of these “discoveries “ are mentioned in the Bible. Now they trying to “discover“ something that can discredit those findings.
    If it takes millions of years for a star to form, there’s no way to tell in a few years if a region is a “star forming”region. There is not enough time. If you going back in time millions of years, the sky should have less and less stars in it right?
    We see stars die, but never have we seen one form.
    This is because God made the heavens and the earth and then said, IT IS FINISHED. So they are desperate to find a star forming region. So desperate that I can see them faking it just like the missing links Lucy, pelt down man, geologic column, dinosaurs , embryo chart. ….

  48. This technology has been around a long time , just not open to the public, dont believe me? Look up the orion cube

  49. So they know how far stars are away, then they should know that they are not anything like the sun?

  50. Lies over lies that deceive your eyes…I've been to countries 20 years ago that hadn't the money to generate enough energy to feed or even build an infrastruction of streetlights to the farest hillbilly villages to enlighten them all night long (where it & what isn' t even necessary ! – if you dont want to light-pollute the skies over all people just to make us unable to examinate whats really going on up there) You'd see a billions of stars, meteroids & asteroids that are the only heavenly bodies that aren't circling around but fly straight or curved trough the visible sky. If everything was moving on their own tracks, how comes that all the stars and galaxies are keeping the same distance to each other for over hundreds & thouands of years!? Only if you watch the sky over a periode of houres you can see, that they circle over our visible sky -horizont. But governments build streets and rasters of lights like a net just to take your free sight on the night-sky! Wouldn't it be more important to invest that money for people in need, who hunger till death or need medical support or at least clean water to drink!? Think about that for a moment. If somebody will say "Oh thats a good thing its only for security we need that streetlights" …then I ask you – in our times? Really? Aren't we capeable of putting move-detectors or buttons on particular parts of streets or ways or at crossroads in that areas or even in city's infrastructure that streetlights will only turn on, if a person or a car is passing by or entering a certain block where they want to go?! Why must the laterns glow/burn all through the night & everywhere at the same time? It only costs a lot of energy & much more of our taxes that could be used otherwise & better!! Its all about disconnecting the people from the heaven and the stars above. They would give enough light anyways to find our way…well, if you are used to artificial light it will take some time but it will regenerate after some time. But thats not what the responsible people wants to happen

  51. How do you know the distance for example a star a million years away you cannot travel there measure the distance and comeback if you shoot a laser at it will take a million years to get there and another to comeback ow do you know?

  52. our galaxy is 500 000 light years in radius including the galactic halo
    our galaxy is more massive than andromeda
    our galaxy has ripples that were caused probably by a collision with another mini like galaxy
    our galaxy has rings, stellar streams
    our galaxy spins at 800 000 kilometres per hour meanwhile the galactic halo spins in the same direction at 600 000 kilometers per hour

  53. Does anyone even care about the scale of these images?
    Has anyone stopped these exploreres to explore about improving the life and sytem we have on this planet.
    Brutal irony.
