Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny ...

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

Galaxies might be separated by hundreds of thousands of light-years at the very least, but they do occasionally merge. During those collisions, the supermassive black holes that sit at the center of ...

Observations from NASA’s James Webb Space Telescope and other telescopes have shown what appears to be a supermassive black hole forming right between two merging galaxies. There have been multiple ...

Astronomers combined data from NASA’s JWST and Chandra X-ray Observatory to create a stunning new image of two merging spiral galaxies ...

Two massive galaxy clusters are slamming into each other, and for once astronomers are not reconstructing the crash from the debris long after the fact. They have caught the system in the act, with ...

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 ...

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave ...

Perched high in the foothills of Chile’s Andes mountains, a revolutionary new space telescope has just taken its first pictures of the cosmos—and they’re spectacular. Astronomers are excited about the ...
