Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

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 ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

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 ...

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 ...

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 ...

This mash-up of data from the James Webb Space Telescope and the Chandra X-ray Observatory reveals two galaxies mid-collision, with their spiral arms overlapping and bending toward their neighbors' ...
