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

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.

Astronomers have long thought the Milky Way was destined to merge with the nearby Andromeda galaxy. The aftermath of this predicted clash has been dubbed “Milkomeda,” and researchers predicted ...

Our possible futures: Three scenarios for a future encounter between the Milky Way and Andromeda galaxies. Top left: The two galaxies bypass each other at a separation of 1 million light-years. Top ...

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 ...

Shockingly Tiny Galaxy Near Andromeda Is Just One-Millionth the Size of the Milky Way The fully formed galaxy is remarkably teeny, raising new questions about how galaxies emerge and evolve.

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.

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.

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.
