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 ...

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

Milky Way galaxy might not collide with Andromeda after all Astronomers ran 100,000 computer simulations using combined Hubble/Gaia space telescope data.

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

The odds of a galactic collision in our distant future are much lower than we thought, according to new simulations.

Astronomers reported Monday that the probability of the Milky Way and Andromeda galaxies colliding is less than previously thought.

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.

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.

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.

Astronomers have long thought that the Milky Way is headed for an inevitable crash with its neighbor, Andromeda. But a new study complicates the story.
