Supermassive black holes usually lurk unseen, but when an unlucky star drifts too close they ignite titanic outbursts ...

NASA, ESA, and ground observatories have detected powerful space explosions caused by black holes tearing apart massive stars. These extreme nuclear transients, like the event nicknamed “Barbie,” ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

Hubble Space Telescope snapped an image of UGC 11397, a spiral galaxy situated in the constellation Lyra, about 250 million ...

NASA, ESA, and ground observatories have observed black holes causing the most powerful space explosions ever recorded, revealing previously hidden black holes.

Hubble spotted a rare off-center black hole shredding a star, revealing the first optical discovery of a wandering ...

For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are ...

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

The discovery, made with the LOFAR (LOw Frequency ARray) radio instrument in Europe, indicates that galaxy clusters, which ...

Researchers say there are far more supermassive black holes out there than we previously suspected, and they're starting to ...

But since only 10% of early black holes are actively eating gas and dust, extreme nuclear transients — that is, catching a supermassive black hole in the act of eating a massive star — are a different ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 ...
