The quasi-periodic eruptions of X-rays from a black hole 300 million light-years away are unlike any researchers have ever ...

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

A distant galaxy that lay quiet for decades has suddenly stirred, lighting up in dramatic bursts that have caught astronomers ...

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at ...

The black hole now gives off powerful X-rays at nearly regular intervals. These outbursts are known as quasi-periodic eruptions (QPEs), and have been observed emitting from other black holes. But ...

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

Now, astronomers are getting a close look at a black hole that is “waking up” and going from a dormant state to an active one as it starts chowing down on nearby matter. The black hole at the ...

QPEs are short-lived flaring events. And this is the first time we have observed such an event in a black hole that seems to be waking up,” lead author Lorena Hernández-García, a researcher at ...

Primordial black holes are ancient mysteries, born in the universe’s earliest seconds. Unlike regular black holes, they weren ...

Black holes are made of matter packed so tightly that gravity overwhelms all other forces. When you pick up a bowling ball, it’s heavy because the matter is densely packed. If you packed more and more ...

This artist’s impression illustrates the mechanism that could be at the origin of the powerful bursts of X-ray light seen from a newly awakened black hole named Ansky.
