An examination of earlier observations from the wide-field X-ray telescope revealed another persistent X-ray signal preceding the gamma ray burst, which is an odd order of events for high-energy ...

Astronomers have reported an unusually high-energy event that may represent a rare form of black hole feeding. The transient, named EP250702a, was fir.

Astronomers have discovered the closest black hole to Earth. It's so close that its sister stars can be seen with the naked eye. Wednesday's announcement backs up the theory that there are lots of ...

A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole. The study, coordinated by Dongyue Li and Wenda Zhang of the Chinese Academy of ...

Astronomers suspect that in the first second after the universe formed, the very first black holes also formed. These tiny though profoundly dense objects — think of an atom-sized particle wielding ...

Black holes are one of the most devastating objects in space, sucking up everything around them. But there's another space phenomenon that's just as destructive, and it's known as a white hole. Now, ...

Size matters when it comes to telescopes. The bigger they are, the farther they can see. Prioritizing constructing large ones is therefore high on the priority list for many observational ...

Meet your new but shy galactic neighbor: A black hole left over from the death of a fleeting young star. European astronomers have found the closest black hole to Earth yet, so near that the two stars ...
