A collision between our Milky Way galaxy and the neighboring Andromeda galaxy, long considered inevitable, may be in question, astronomers say.

New data show a 50% chance the Milky Way won't collide with Andromeda. A merger with the Large Magellanic Cloud is far more likely.

For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has ...

Our galaxy may not collide with its neighbour after all, suggests new research. For over a century, astronomers believed a dramatic collision between Milky Way and Andromeda galaxies was ...

The long-proposed Milky Way and Andromeda galactic merger might not be as certain as astronomers previously believed.

New data from NASA's Hubble Space Telescope has created uncertainty in the theory that the Milky Way and Andromeda will collide and merge.

For over a decade, researchers have suggested a high possibility of our Milky Way galaxy smashing into neighboring galaxy Andromeda around 5 billion years from now. The collision would merge the ...

Our neighboring Andromeda Galaxy (Messier 31, or M31) appears to sport a lopsided arrangement of satellite galaxies that defy scientific models, stumping astronomers who are also trying to figure ...

The distance between the Milky Way and Andromeda in 50 simulations. Just slightly more than half of orbits result in a Milky Way - Andromeda collision within 10 billion years.

The Milky Way and the neighboring Andromeda galaxy are currently hurtling through space toward each other at a speed of about 250,000 miles per hour (400,000 kph), setting up a possible future ...

Three simulations showing Milky Way and Andromeda bypass at 1 million light year separation. At 500,000 light-years, dark matter provides friction that brings galaxies to a close encounter.
