Astronomers have long predicted that a collision between our galaxy and nearby Andromeda could be inevitable, but new ...

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

An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.

The collision between the Antennae galaxies, which are located about 62 million light-years from Earth, began more than 100 million years ago and is still occurring.

These findings will help scientists understand how giant galaxies interact, collide, and merge to produce even bigger galaxies where gravity draws them together across chasms of space-time.

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all.

Scientists hace created an atlas of colliding galaxies previewing the ultimate fate of our Milky Way galaxy, which is set to collide with its neighbor, Andromeda.

The colliding Antennae galaxies appear here at a relatively early stage of the collision process, which began about 500 million years ago. The collision has triggered the formation of millions of ...

465 million light-years away, two galaxies are colliding. Immense tidal forces have distorted both galaxies, leaving the larger one noticeably off-kilter.

Scientists have managed to capture, for the first time, a series of images showing what happens when galaxies collide and merge together, causing a massive explosion and supermassive black holes ...
