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

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

What can astronomers learn from observing black holes that suddenly wake up? This is what a recent study published in Nature ...

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

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

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.

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a ...

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 ...

Could our galaxy actually be inside a black hole? New research seems to suggest this possibility. NASA's James Webb Telescope discovered that the rotation of the galaxies goes against what scientists ...
