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.

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.

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 ...

What does the Milky Way look like?. Sometimes, the billions of stars comprising our home galaxy appear especially vibrant during “Milky Way season” as the band arcs across the night sky. The ...

But the only way to get to a new prediction about the eventual fate of the Milky Way will be with even better data.” DOI: Nature Astronomy, 2025. 10.1038/s41550-025-02563-1 ( About DOIs ).

While the Milky Way is generally always visible from Earth, certain times of year are better for stargazers to catch a glimpse of the band of billions of stars comprising our galaxy.

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.

Milky Way's chance of colliding with Andromeda? New study puts odds at 50-50 For this new study, the scientists relied on updated galaxy measurements to factor in the gravitational pull on the ...
