https://howfarawayisit.fandom.com/wiki/Encyclopedia_Howfarawayica In this segment of our “How far away is it” video book, we cover interacting or colliding galaxies.
We describe what it means for galaxies to collide given the great distances between stars within each galaxy. We then take a look at some of the interacting galaxies photographed by the Hubble Telescope. These include: The Antennae Galaxies, The Mice, NGC 2207 with IC 2163; Apr 256; ESO 576-69; APR 142; NGC 6240; the Tadpole Galaxy; UCG 1810 with UCG 1813; the spectacular APR 147; NGC 454; South America Galaxy; and ZW II 28.
We spend some time on peculiar galaxy NGC 7603 with its multiple red-shift objects that challenge well accepted theories on Dark Matter and Cosmology.
Next, we discuss how we go about seeing a process that takes a billion years by observing interactions at various stages along the process as understood by computer simulations. Here we show a few that illustrate the phases of an interaction: the initial approach with NGC 6786 and LEDA 62867; first contact with VV 304A and VV 304B; penetration with Mayall’s Object; out the other side with ESO 77-14; wrap around with VV 705; and merge with The Owl.
We end with another simulation. This time it’s the collision between Andromeda and the Milky Way. Music:

Infinity & Beyond — Episode 5: The Milkomeda Collision
Our galaxy, the Milky Way, and its nearest large neighbor, the Andromeda Galaxy (M31), are on a collision course. Billions of years from now, the merger will transform the structure of both galaxies and create a new arrangement of stars we have dubbed Milkomeda (“milk-AHM-mee-da”). The merger will radically transform the night sky. But into what? Currently, the Milky Way’s thin disk of stars and gas appears as a nebulous strip arching across the summer sky. As Andromeda grazes the Milky Way, a second lane of stars will join the one that presently graces the night sky. After the final merger, the stars will no longer be confined to two narrow lanes, but instead scatter across the entire sky. Join host Abigail Bollenbach as she walks you through our galaxy's impending date with destruction.

TWITTER ➜ https://www.twitter.com/astrobytez If it was possible to travel anywhere in the galaxy, the next step in our epic journey would be travelling to our nearest major galaxy, which is Andromeda. It is 2.5 million light years away from Earth. It is the most distant naked eye object you can see in the night sky. Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. It is the nearest major galaxy to the Milky Way and it gets its name from the area of the sky from which it appears the constellation of Andromeda, which was named after the Greek mythological princess Andromeda. Here are five fascinating facts about the Andromeda galaxy. 5. Andromeda Has One Trillion Suns.
There are around one trillion suns in the Andromeda Galaxy, compared to between 100 and 400 billion stars for our own Milky Way galaxy. Not only does it have a lot more stars than the milky way, Andromeda is enormous with a diameter of around 220,000 light-years across, which is nearly one and a half times longer than the Milky Way. Despite that, the mass of the Andromeda Galaxy is only 400 billion times that of our own Sun. The Milky Way is imagined to be considerably heavier because it probably possesses more Dark Matter and Dark Energy than the Andromeda galaxy.
4. Andromeda Appears Six Times the Size of our Moon.
3. Andromeda is Full of Black Holes.
2. Andromeda and Milky Way will collide.
1. Andromeda Was Once Thought To Be A Nebula.
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 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
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.

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
