Why Do Galaxies Rotate?
If you believe the world’s leading physicists, the vast majority of matter in the universe is hiding in plain sight. For nearly a century, evidence has mounted that the gravitational pull necessary to keep clusters of galaxies intact, as well as stars within galaxies from flying apart, requires far more matter than we can see—matter, according to the experts, that has eluded our telescopes, because it does not give off light. Problem is, such “dark matter” has also eluded one specially designed detector after another that researchers have deployed to catch it. Which raises the big question: What if we have failed to find dark matter because it isn’t there? Join leading physicists on a scientific treasure hunt that has proved more challenging than anyone expected, and may ultimately require rethinking some of our most fundamental ideas about the universe.

The science of expansion: Andromeda, gravity, and the ‘Big Rip’ | Michelle Thaller
New videos DAILY: https://bigth.ink Join Big Think Edge for exclusive video lessons from top thinkers and doers: https://bigth.ink/Edge ---------------------------------------------------------------------------------- The Andromeda Galaxy and our Milky Way are on a collision course that will obliterate life on Earth 4.5 billion years from now.The universe is expanding in all directions, all at once – so why are Andromeda and the Milky Way drawing nearer? The gravity between them is a stronger force than expansion.The rate of expansion is accelerating. If it continues to speed up, its force may become strong enough pull things apart that are currently held together by superior forces: Our galaxy, the solar system, and even the atoms in our bodies. That possible ending to the universe is known as the 'Big Rip'. ---------------------------------------------------------------------------------- MICHELLE THALLER Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory's (JPL) Spitzer Space Telescope. After a hugely successful mission, she moved on to NASA's Goddard Space Flight Center (GSFC), in the Washington D.C. area. In her off-hours often puts on about 30lbs of Elizabethan garb and performs intricate Renaissance dances. For more information, visit
NASA. ---------------------------------------------------------------------------------- TRANSCRIPT: MICHELLE THALLER: One of the questions I get asked most commonly as an astronomer is if almost all the galaxies in the universe are flying away from us in space, why is the Andromeda Galaxy getting closer to us? Does that somehow mean that the Big Bang works differently in different parts of the universe? And the answer simply is: no. Space is expanding because of the Big Bang. All of space is expanding in every direction all at once and from our viewpoint that means that it looks like all the other galaxies are moving away from us. But not all the universe around us appears to be expanding. For example, the Earth doesn't seem to be getting any farther away from the Sun. The Sun is not getting any farther away from our galaxy. Thank about smaller scales, like your body; your body (luckily) is not expanding along with the universe. And the reason is that the expansion of the universe is actually a pretty gentle force; you really only notice it out in the middle of nowhere in the vast reaches of space between the galaxies. There's a lot of space out of there, so there is a lot of space to expand and so you really notice this expansion. But there are things that are stronger than the expansion force. For example, my body is held together by chemical forces and by electrical forces. That is much, much stronger than the tiny little push that space has to expand inside me. I hold together very well. One of the analogies I think about is: You could try to push over the Empire State Building by blowing on it. You are actually exerting a force on the Empire State Building by blowing on it, you can measure that force, but you're not going to blow over the Empire State Building. There are things that are much stronger than this omnipresent but gentle force of the expansion of the universe. The gravity between the Sun and the Earth is stronger than space's pressure to expand over that scale. The force of gravity is stronger than the outward push of the expansion of the universe. That's also true of the galaxy, we are held in orbit around the center of the galaxy. Gravitationally, that's much stronger than any expansion force. So why is Andromeda different? Andromeda is close enough to our Milky Way Galaxy that the gravity between the two is strong enough for the two to start moving together. Yeah, space is expanding between us and the Andromeda Galaxy, but gravity is accelerating Andromeda toward us faster than that expansion. And, in fact, that means that Andromeda is going to collide with the Milky Way in a couple billion years. And we see this happening all over the universe. There are clusters of galaxies where the galaxies are close enough together that they are merging and colliding. When galaxies are far enough away from each other that the gravitational force is weaker, the acceleration due to gravity is weaker than the outward expansion, then they start moving away. Now one of the intriguing things is that we don't know what the future holds when it comes to the expansion force of the universe. Just recently in the last couple of decades we've measured...

OTD in Space - Dec. 15: Andromeda Galaxy Spotted by Telescope for the 1st Time
On Dec. 15, 1612, the Andromeda galaxy was seen through a telescope for the first time by a German astronomer named Simon Marius. The Andromeda galaxy is the closest major galaxy to the Milky Way, and it can be seen with the naked eye. Early astronomers thought it was a nebula, or a glowing cloud of space dust. Even after Simon Marius saw it through a telescope for the first time, he still couldn't tell that it was actually a galaxy filled with about a trillion stars. It took another three hundred years before Edwin Hubble came along and figured out that it was a galaxy.

Our Nearest Galactic Neighbor Is A Cannibal And It Ate Our Galactic Sibling
According to a report by Geek.com, a new discovery by researchers at the University of Michigan has uncovered our Milky Way galaxy's long-lost, and long-dead, stellar sibling. The new study shows that our nearest galactic neighbor, the Andromeda galaxy, cannibalized another massive galaxy two billion years ago. "A rich trail of evidence" left behind after the galaxy, named M32p, was devoured has helped scientists understand how disk galaxies like the Milky Way evolve and survive. It turns out the consumed galaxy was at least 20 times larger than any galaxy that ever merged with the Milky Way, and had been the third-largest member of the so-called Local Group.

Scientists Claim The Milky Way's Long-Lost Sibling Was Cannibalized By Andromeda
According to a new study published Monday in the journal Nature Astronomy, two billion years ago, our Milky Way galaxy's sibling, known as M32p, was violently cannibalized by our closest and largest galactic neighbor, Andromeda. CNN reports that the large neighboring galaxy is expected to have consumed hundreds of surrounding smaller galaxies. Before being consumed, the M32p galaxy was reportedly the third largest galaxy behind Andromeda and the Milky Way and was at least 20 times larger than any galaxy that ever merged with the Milky Way. Both evidence and computer simulations allowed researchers to reconstruct the events leading up to galaxy M32p's demise approximately 2 billion years ago.

Milky Way is as big as Andromeda - SpaceTime with Stuart Gary S21E16
*Milky Way is as big as Andromeda
A new study claims our nearest big neighbour the Andromeda galaxy M-31 and our own galaxy the Milky Way are about the same mass. The findings contradicts earlier studies which concluded that Andromeda was two to three times larger than the Milky Way. *New Hubble constant hinting at strange new physics beyond the standard model
Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements yet of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the new results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe. *The most distant supernova ever seen
Astronomers have confirmed the discovery of the most distant supernova ever detected. The findings claim the huge cosmic explosion took place 10.5 billion years ago – meaning it’s taken some three-quarters of the age of the universe for light from the blast to reach Earth. *The Science Report

The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth. It is the nearest major galaxy to the Milky Way and It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the Greek mythological princess Andromeda. So next time you look up at the nights sky and see the distant glimmer of the extragalactic stars, remember these 5 fascinating facts about the Andromeda galaxy! 1 - Andromeda can be seen with the unaided eye, which has meant that it has been known since ancient times. On a clear night with little light pollution, it can be seen as a diffuse blur, with the central region clearly visible through a good pair of binoculars. Larger telescopes provide even more-spectacular views of this impressive galaxy. 2 - Andromeda is the biggest galaxy by volume, it contains around twice the number of stars than our galaxy, the Milky Way, which has around 200-400 billion. Not only does it have a lot more stars than ours, Andromeda is enormous, with a diameter of around 220,000 light years across, which is nearly 1 and half times longer than the Milky Way. 3 - Because Andromeda is so visible on a clear night, astronomers have studied its history for decades. It is estimated to of been born 10 billion years ago out of the merger of many smaller proto galaxies and then, around 8 billion years ago, it collided with another galaxy to form the giant that we see today. 4 - Like our own galaxy, there’s also a super massive black hole at the centre of Andromeda, with two others possibly orbiting as a binary, with a mass around 140 million times that of the Sun. Dozens of smaller black holes are also believed to lye in the centre and many more have been picked out by the Chandra X-ray Observatory though out the galaxy. 5 - Our neighboring galactic bully is on another collision course, but this time with us. Both the Milky Way and Andromeda are moving towards each other at a rate of 75 miles a second, when the collision has been completed, they will merge to form a giant elliptical galaxy. However this is estimated to happen in around 3.75 billion years from now. So nobody has to panic for a low time. Attributes -

Hubble Finds Giant Halo Around the Andromeda Galaxy
The Andromeda galaxy is our Milky Way's nearest neighbor in space. The majestic spiral of over 100 billion stars is comparable in size to our home galaxy. At a distance of 2.5 million light-years, it is so close to us the galaxy can be seen as a cigar-shaped smudge of light high in the autumn sky. But if you could see the huge bubble of hot, diffuse plasma surrounding it, it would appear 100 times the angular diameter of the full Moon! The gargantuan halo is estimated to contain half the mass of the stars in the Andromeda galaxy itself. It can be thought of as the "atmosphere" of a galaxy. Astronomers using Hubble identified the gas in Andromeda's halo by measuring how it filtered the light of distant bright background objects called quasars. It is akin to seeing the glow of a flashlight shining through a fog. This finding promises to tell astronomers more about the evolution and structure of one of the most common types of galaxies in the universe. Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss this latest finding from #Hubble with the astronomers who made the observations. Read more here:

Left Spine Down - “X-Ray”
https://www.youtube.com/watch?v=4tcoZNrSveE&feature=youtu.be I don’t want to freak you out, but you should be aware that there’s a gigantic galaxy with twice our mass headed right for us. Naw, I’m just kidding. I totally want to freak you out. The Andromeda galaxy is going to slam head first into the Milky Way like it doesn't even have its eyes on the road. This collision will tear the structure of our galaxy apart. The two galaxies will coalesce into a new, larger elliptical galaxy, and nothing will ever be the same again, including your insurance premiums. There’s absolutely nothing we can do about it. It’s like those “don’t text and drive commercials” where they stop time and people get out and have a conversation about their babies and make it clear that selfish murderous teenagers are really ruining everything for all of us all the time. And now that we know disaster is inbound, all we can do is ask WHY? Why this is even happening? Isn't the Universe expanding, with galaxies speeding away from us in all directions? Shouldn't Andromeda be getting further away, and not closer? What the hay, man! Here’s the thing, the vast majority of galaxies are traveling away from us at tremendous speed. This was the big discovery by Edwin Hubble in 1929. The further away a galaxy is, the faster it’s moving away from us. The most recent calculation by NASA in 2013 put this amount at 70.4 kilometers per second per megaparsec. At a billion light-years away, the expansion of the Universe is carrying galaxies away from us at 22,000 km/s, or about 7% of the speed of light. At 100 million light-years away, that speed is only 2,200 km/s. Which actually doesn't seem like all that much. Is that like Millenium Falcon fast or starship Enterprise Warp 10 fast? Andromeda is only 2.5 million light-years away. Which means that the expansion of the Universe is carrying it away at only 60 kilometers per second. This is clearly not fast enough for our purposes of not getting our living room stirred into the backyard pool. As the strength of gravity between the Milky Way and Andromeda is strong enough to overcome this expansive force. It’s like there’s an invisible gravity rope connecting the two galaxies together. Dragging us to our doom. Curse you, gravity doom rope! Andromeda is speeding towards us at 110 kilometers per second. Without the expansion of the Universe, I’m sure it would be faster and even more horrifying! It’s the same reason why the Solar System doesn't get torn apart. The expansion rate of the Universe is infinitesimally small at a local level. It’s only when you reach hundreds of millions of light-years does the expansion take over from gravity.
You can imagine some sweet spot, where a galaxy is falling towards us exactly as fast as it’s being carried away by the expansion of the Universe. It would remain at roughly the same distance and then we can just be friends, and they don’t have to get all up in our biz. If Andromeda starts complaining about being friend-zoned, we’ll give them what-for and begin to re-evaluate our friendship with them, because seriously, no one has time for that.
The discovery of dark energy in 1998 has made this even more complicated. Not only is the Universe expanding, but the speed of expansion is accelerating. Eventually distant galaxies will be moving faster away from us than the speed of light. Only the local galaxies, tied together by gravity will remain visible in the sky, eventually all merging together. Everything else will fall over the cosmic horizon and be lost to us forever. All things in the Universe are speeding away from us, it’s just that gravity is a much stronger force at local levels. This is why the Solar System holds together, and why Andromeda is moving towards us and in about 4 billion years or so, the Andromeda galaxy is going to slam into the Milky Way.
Zooming in on the Andromeda Galaxy
This video begins with a ground-based view of the night sky, before zooming in on a Hubble image of the Andromeda galaxy — otherwise known as M31. The new Hubble image of the galaxy is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40 000 light-years.

Milky Way's Head On Collision
This animation depicts the collision between our Milky Way galaxy and the Andromeda galaxy. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now. Around 6 billion years from now, the two galaxies will merge to form a single galaxy. The video also shows the Triangulum galaxy, which will join in the collision and perhaps later merge with the Andromeda/Milky Way pair.

How Far Away Is It - 11 - Andromeda and the Local Group (1080p) see update
(Newer version at http://youtu.be/IhP1GnAvm0w) Text at http://howfarawayisit.com/documents/ In this segment of our "How far away is it" video book, we cover the Andromeda galaxy along with our local group of galaxies, including some of the dwarf galaxies orbiting the Milky Way. We begin with Edwin Hubble's discovery of a Cepheid variable star in what was thought to be a Milky Way nebula. The star was V1 and it changed the history of astronomy. We cover the black hole at the center of Andromeda, highlight the size of this beautiful galaxy with its trillion stars, and point out what was going on here on our planet when the light we see left Andromeda on its journey into our telescopes. Next we identify the local group of galaxies including: Triangulum with its great star birth H II region NGC 604; irregular galaxy NGC 6822 with its unique Hubble V H II region; the recently discovered galaxy IC 10; nearly edge on galaxy NGC 3109; and Sextans A. Then we focus on the two main galaxies orbiting the Milky Way -- the Large Magellanic Cloud and the Small Magellanic Cloud. Then we take a look at some of the amazing nebula within these two dwarf galaxies including: Supernova Remnant N 63A, SN 0509-67.5, the Tarantula Nebula, 30 Doradus, Hodge 301, the Double Bubble, LH 95, NGC 2074, NGC 602, and NGC 346. We conclude with a review of the galaxies we covered marked on a map of the Local Group. STEM
