It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

Astronomers now believe the Milky Way's "inevitable" collision with a neighboring galaxy is much less likely than originally thought.

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...

CNN — A new telescope image showcases two entangled galaxies that will eventually merge into one millions of years from now -- and previews the eventual, similar fate of our own Milky Way galaxy. The ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

New observations of a pair of colliding spiral galaxies hint at what might be in store for the Milky Way and the Andromeda galaxy if and when they collide. The findings, described in July in the ...

NASA has released a new composite image of two spiral galaxies, NGC 2207 and IC 2163, as they begin a multi-billion-year process of merging into a single celestial entity. This event was captured with ...

Recently, two NASA space telescopes, the James Webb Space Telescope and Chandra X-Ray Observatory, captured images of two galaxies beginning to collide. NASA released a composite image showing both ...
