You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers ...

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 ...

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 ...

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 ...

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 ...

Learn how dozens of galaxies may have merged into a giant galaxy shortly after the Big Bang.

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

The James Webb Space Telescope has peered through cosmic dust to reveal new details and a stunning image of a rare type of galaxy. The space observatory's latest image shows the Cartwheel galaxy, a ...

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 ...

Examples of merging galaxies containing a heavily obscured growing supermassive black hole observed by the Hubble Space Telescope. The top panels show nearby galaxies at ~500 million light-years from ...
