Astronomers believe they may have witnessed a massive black hole wake up and become active in a far-away galaxy.

A black hole 360 million light years away from Earth suddenly begun shining brighter and consuming material within its pull. Scientists say it's the first time they've witnessed the phenomenon in real time.

The mysterious brightening of a distant galaxy is thought to be caused by a black hole ‘feasting’ on the surrounding gas.

A similar awakening may one day occur with the Milky Way's supermassive black hole

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European…

The mysterious brightening of a distant galaxy is thought to be caused by a black hole ‘feasting’ on the surrounding gas.

In late 2019, galaxy SDSS1335+0728 brightened unexpectedly. Astronomers used observatory data to track its brightness, revealing a massive black hole awakening at its core.

Scientists have captured the moment a terrifying supermassive black hole 'awakens' in a distant galaxy, and warn that the same thing could happen in the Milky Way

Five years ago, a galaxy 300 million light-years away got a lot brighter in telescopes, radiating ultraviolet, optical, and infrared light out into space. This year, the resurgent galaxy started emitting X-rays, indicating that its initial…

Astronomers believe the 2019 brightening of galaxy SDSS1335+0728 may be the first real-time observation of a massive black hole awakening. The galaxy’s persistent increase in...

Mysterious brightening of distant galaxy believed to be caused by material falling into huge black hole

"We were able to observe the awakening of the massive black hole, [which] suddenly started to feast on gas," researcher Claudio Ricci said.

A surprisingly normal looking quasar when the Universe was 750 million years old.

The early Universe was a strange place. Early in its history—in the first quintillionth of a second—the entire cosmos was nothing more than a stunningly hot plasma. And, according to researchers at the Massachusetts Institute of Technology…

Astronomers believe that at the heart of most, if not all, galaxies sits a titanic black hole with a mass that is millions or even billions of times that of our sun. These supermassive black holes cannot be directly created through the…
