Both the Milky Way and the Andromeda galaxies (M31) are part of what's known as the Local Group (LG), which also hosts other ...

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

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

Close stellar encounters could change the structure of our planetary system, potentially dooming Earth or other worlds to ...

"As it stands, proclamations of the impending demise of our Galaxy seem greatly exaggerated." That's the conclusion scientists have reached after revisiting the possibility of what we thought was a ...

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 ...

The Milky Way was on a collision course with a neighboring galaxy. Not anymore. NASA scientists had forecast an impending crash in four billion years, sending the sun flying ...

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. But new ...

But the Large Magellanic Cloud, whose orbit intersects those of the Milky Way and Andromeda, makes it less likely. In short, it's a real "will they, won't they?".

Astronomers thought the Milky Way was doomed to crash into Andromeda. Now they're not so sure. ... slow orbit around each other—close companions that never quite collide.
