Andromeda–Milky Way collision - Wikipedia
The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
NASA’s Hubble Shows Milky Way is Destined for Head-On Collision
2012年5月31日 · NASA astronomers announced Thursday they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy.
Milky Way may escape fated collision with Andromeda galaxy
2024年8月9日 · For years, astronomers thought it was the Milky Way’s destiny to collide with its near neighbor the Andromeda galaxy a few billion years from now. But a new simulation finds a 50% chance the impending crunch will end up a near-miss, at least for the next 10 billion years.
The Andromeda and Milky Way collision, explained - Astronomy …
2023年12月1日 · The Andromeda Galaxy is approaching the Milky Way at nearly a quarter million miles per hour. It is the closet major galaxy to our Milky Way and is the most distant thing you can see with the...
The Milky Way and Andromeda may not merge, after all
2024年9月30日 · Our Milky Way Galaxy and the Andromeda Galaxy are (likely) destined to collide nearly head on in a few billion years. In one possible scenario, the smaller Pinwheel Galaxy (M33) misses the...
Will our galaxy really collide with Andromeda? Maybe not
2024年8月22日 · Astronomers have long considered it inevitable that our home galaxy, the Milky Way, will merge with the neighboring Andromeda galaxy within the next 5 billion years. However, a new simulation...
Will the Milky Way and Andromeda Galaxies Ever Collide?
2024年8月23日 · Andromeda and the Milky Way may collide, or they may safely swing past each other. Time will tell. A pair of far-distant colliding spiral galaxies, as seen by NASA’s Hubble and Spitzer space...
[0705.1170] The Collision Between The Milky Way And Andromeda …
2007年5月8日 · We use a N--body/hydrodynamic simulation to forecast the future encounter between the Milky Way and the Andromeda galaxies, given current observational constraints on their relative distance, relative velocity, and masses.
The Fate of the Milky Way, Andromeda, and Triangulum Galaxies
2012年5月31日 · Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together in a head-on collision about 4 billion years from now. The thin disk shapes of these spiral galaxies are strongly distorted and irrevocably transformed by the encounter.
Future merger of the Milky Way with the Andromeda galaxy and …
2021年2月22日 · We used direct $N$-body simulations to model this interaction to shed light on the future of the Milky Way - Andromeda system and for the first time explore the fate of the two supermassive black holes (SMBHs) that are located at their centers.
