A supermassive black hole in a distant galaxy is once again surprising scientists. In 2018, a black hole called 1ES 1927+654, located about 270 million light-years away from Earth, showed its first ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

While black holes suck in light, white holes gush light outward. Objects cannot avoid being pulled to the center of a black hole, but would not be able to reach the center of a white hole.

Black holes themselves emit no light, but the supermassive black holes at the centers of galaxies are often surrounded by huge clouds of material. It's this material, heated by friction and gravity as ...

Astronomers detected X-ray flashes from the black hole that increased in frequency from one every 18 minutes to one every ...

Regular pulses of X-ray radiation emanating from a supermassive black hole could be explained by a white dwarf star on the ...

"This would be the closest thing we know of around any black hole," Megan Masterson, a physicist at MIT who co-led the research, said in a statement. "This tells us that objects like white dwarfs ...

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.

Astronomers theorize that a low-mass white dwarf, a compact core of a dead star about as large as Earth, could be the culprit. A cosmic mystery surrounding a black hole some 270 million light ...
