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][2][3][4][5] The stars involved are sufficiently far apart that it is improbable that any of them ...

2023年12月1日 · In about 4 billion years, our home galaxy will merge with the nearest large spiral in the Local Group. Here's what will happen. Billions of years from now, the night sky will glow …

2012年5月31日 · 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.

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 …

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...

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.

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.

2012年6月1日 · About 3.75 billion years from now, Andromeda’s disk fills the field of view and its gravity begins to create tidal distortions in the Milky Way. The view is inspired by dynamical computer...

2024年8月19日 · Located roughly 2.5 million light-years away, the Andromeda (M31) galaxy is approaching our Milky Way at a speed of 68 miles per second (110 kilometers per second).

2025年1月16日 · The Milky Way, on the other hand, hasn’t had a collision with another galaxy in about 8 to 10 billion years, he said. The two galaxies have a linked fate, however. “In 5 billion years, Andromeda will collide with the Milky Way, and we’ll just have eventually one big elliptical galaxy left in the local group,” he said.
