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.

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 with stars, dust,...

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...

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...

2018年5月23日 · The three largest galaxies in our Local Group of Galaxies are our Milky Way along with the Andromeda (also known as Messier 31) and Triangulum (also known as Messier 33) galaxies. This scientific visualization of a computer simulation depicts their joint evolution over the next several billion years and features the inevitable massive collision ...

2013年6月12日 · Andromeda, also known as Messier 31 (M31), is a spiral galaxy located about 2.5 million light years away. It is thought that the Milky Way and Andromeda will collide several billion years from now. The black holes located in both galaxies will then reside in the large, elliptical galaxy that results from this merger.

2020年10月3日 · The strong gravitational attraction between the Milky Way and Andromeda wins out over the dark energy attempting to drive them apart, and will ultimately cause a collision to occur. But don’t lose any sleep over our inevitable collision with Andromeda, it won’t happen for a few billion years!

2023年4月17日 · Call it a “Tale of Two Galaxies”: our Milky Way and neighboring Andromeda (M31). Astronomers have described these galaxies as resembling twins. Both are spiral galaxies with long, coiled arms of gas. They grew up in the same cosmic neighborhood. (Andromeda is 2.5 million light-years from Earth.) They are also about the same size, shape, and age.

This video series of photo illustrations shows the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. The sequence is inspired by dynamical computer modeling of the inevitable future collision between the two galaxies. 1: Present Day – This is a nighttime ...
