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.
1 gru 2023 · Learn how the two galaxies will merge to form a giant elliptical galaxy, what will happen to the black holes and the solar system, and how the night sky will change. See simulations, illustrations, and facts about the upcoming cosmic event.
Obecnie galaktyka M31 znajduje się w odległości 2,52 miliona lat świetlnych (ok. 23,5 trylionów km) od Drogi Mlecznej i zbliża się (prędkość radialna) do niej z prędkością około 400 tys. km/h, na co wskazuje przesunięcie ku fioletowi światła docierającego z M31.
31 maj 2012 · NASA astronomers use Hubble Space Telescope data to show that our galaxy will collide with Andromeda in four billion years, forming a new elliptical galaxy. The collision will affect the orbits of stars, but not the sun or Earth.
31 maj 2012 · 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.
9 sie 2024 · 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.
7 lut 2019 · Astronomers have long suspected that Andromeda will one day collide with the Milky Way, completely reshaping our cosmic neighbourhood. However, the three-dimensional movements of the Local Group galaxies remained unclear, painting an uncertain picture of the Milky Way’s future.
