A never-before-seen blast from a supermassive black hole was spotted by two sophisticated X-ray space telescopes. This giant ...

Supermassive black holes are notoriously messy eaters, but the behemoth at the heart of spiral galaxy NGC 3783 really takes ...

Scientists have spotted the brightest flare yet from a supermassive black hole that shines with the light of 10 trillion suns. These bursts of light and energy can come from things like ...

A supermassive black hole around a million times the mass of the Sun just gave away its position in spectacular fashion. When a passing star veered a little too close, it was torn apart in the ...

Scientists observed a supermassive black hole in galaxy NGC 3783 releasing wind at 20% of the speed of light after a sudden X-ray flare. New data from XRISM and XMM-Newton explains how magnetic activi ...

"We were amazed by the fact that these observatories can detect about 100 black holes just 250 million years after the Big Bang. Such detections would greatly help to constrain black hole ...

A monstrous black hole in a distant galaxy has earned itself a nickname worthy of a science-fiction horror movie for its gluttonous feasting on any stars that dare get near. Meet "Space Jaws." ...

Researchers believe the 'ultramassive' black hole is big enough to be the largest of its kind ever detected. Black holes are regions of space where the pull of gravity is so intense that even ...

Primordial black holes that formed during the earliest moments of the universe could have swollen quickly to supermassive sizes, complex cosmological simulations have revealed. The discovery ...

Scientists have discovered a supermassive black hole that appears to be "waking up" after being inactive for decades. The black hole at the heart of SDSS1335+0728—a distant galaxy 300 ...

When black holes emerge out of hiding to feast on their prey and some type of matter is sucked into their celestial maw, they begin to glow brightly. The events, dubbed “extreme nuclear transients ...
