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

"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 ...

Supermassive black holes are seen as sources of wanton cosmic destruction, but there may be more to their powerful influence ...

A white dwarf would also lose angular momentum through gravitational waves, but it also has an additional source of energy. By slowly losing its outermost material to the supermassive black hole ...

It's believed that a dead stellar remnant, or white dwarf, could be spinning precariously on the edge of the black hole, causing the explosions of high-energy light. “This would be the closest ...

"Black holes really do sit at the frontier of human understanding." Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as the ...

“This looked absolutely nothing like a normal black hole.” Astronomers are not sure why that might be happening. The most likely explanation is that there is a spinning white dwarf slowly ...

The supermassive black hole at the center of the Milky Way, called Sagittarius A*, is about four times more massive than this one. White dwarfs are among the most compact objects in the cosmos ...

Now, researchers report that they have caught a supermassive black hole in the act of eating a white dwarf, the last stage of evolution for stars like our Sun – but the white dwarf is not giving ...
