Colliding galaxies can trigger rapid star formation but also cause gas to be expelled. Astronomers used the James Webb Space ...

New observations from the James Webb Space Telescope show that ancient galaxies lived fast and died young because of intense, ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

JWST and radio interferometry caught six massive galaxies colliding 12 billion years ago, while a young supermassive black ...

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 ...

For more than a decade, the collision between the Milky Way and Andromeda galaxies has been treated as a settled fact of ...

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 ...

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 ...

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...

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 ...

Neutron star collision in merging galaxies reveals how cosmic destruction forges heavy elements like gold, offering clues to the universe's chemical evolution. (Nanowerk News) A recently detected ...
