Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum ...

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.

Our cosmic neighborhood may be far more crowded than previous estimates have suggested. New research hints the Milky Way could have many more small dwarf galaxy "satellites" around it than expected.

For this new study, the scientists relied on updated galaxy measurements to factor in the gravitational pull on the Milky Way's movement through the universe. They found that the effects of 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).

Breakthroughs, discoveries, and DIY tips sent every weekday. In roughly 4 billion years, our home Milky Way galaxy may collide with the neighboring Andromeda galaxy.

The computer model also makes use of new mass estimates for other galaxies within the Local Group—a galactic group that hosts the Milky Way and Andromeda, among others.

Our cosmic neighborhood may be far more crowded than previous estimates have suggested. New research hints the Milky Way could have many more small dwarf galaxy "satellites" around it than expected.

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.
