A collision between our Milky Way galaxy and its largest neighbor, the Andromeda galaxy, predicted to occur in about 4.5 billion years, has been anticipated by astronomers since 1912.

Because Andromeda is 2.5 million light years away, its proper motion is very hard to measure. Indeed, no-one had ever done it until the STScI team spent 10 years monitoring the galaxy, which is also ...

There’s now a 50-50 chance this galaxy will crash into ours. Astronomers have long thought that the Milky Way is headed for an inevitable crash with its neighbor, Andromeda.

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 ...

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 ...

In half of them, the Milky Way and Andromeda have a close encounter, losing enough orbital energy to eventually collide. But in most cases, that takes place in the next 8 to 10 billion years.

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

In roughly 4 billion years, our home Milky Way galaxy may collide with the neighboring Andromeda galaxy. We are approaching Andromeda at roughly 250,000 miles per hour, and scientists have ...

Andromeda and the Milky Way may completely miss each by more than 500,000 light-years, meaning no merger. (Image credit: NASA/ESA) The team was able to present different scenarios of what could ...

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. Newsletters Games Share a News Tip. Featured. Featured.

Three future scenarios for Milky Way & Andromeda encounter. Main A 100,000 light-year separation leads to a collision (Bottom left) At 500,000 light-years, dark matter provides friction that ...
