Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth.

"This pushes our models to their limits and challenges our existing ideas about how these X-ray flashes are being generated." ...

"This rare event provides an opportunity for astronomers to observe a black hole's behavior in real time," said astronomer Lorena Hernández-García.

Although we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, ...

Image of the supermassive black hole Sagittarius A* (Sgr A*). from the Event Horizon Telescope (EHT) collaboration "has uncovered strong and organised magnetic fields spiralling from its edge ...

The black hole at the heart of galaxy SDSS1335+0728, located 300 million light-years away, was quiet for decades as it consumed little matter and was in a dormant state. But recently it suddenly lit ...

While black holes are common, radio galaxies are not. Only between 10% and 20% of all galaxies exhibit this phenomenon. Giant radio galaxies are even less common.

A new study of 263 galaxies has provided fresh evidence to support a theory that our universe is the interior of a black hole. Using data from Nasa’s James Webb Space Telescope, researchers at ...

A new discovery using the James Webb Telescope has implied we may live in a black hole. The telescope, launched by NASA three years ago, gives us the ability to take photographs of deep space with ...

This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or astronomers have been measuring the universe’s expansion incorrectly ...

Astronomers are investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behavior unfold in real time offers a unique opportunity to ...
