Something unusual may have risen from the ashes of an epic smashup. In the middle of a galaxy shaped like an infinity symbol — thought to be the result of two galaxies colliding — sits a supermassive ...

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 ...

A faint dwarf galaxy drifting 45 million light-years from Earth may have joined one of astronomy’s strangest clubs. It ...

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

Far beyond the Milky Way, vast collections of galaxies continue to drift, gather and occasionally collide. One such region ...

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 ...

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 ...

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