Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

“Massive black holes are always at the centers of galaxies, but we know that galaxies merge — that is how galaxies grow. And when you have two galaxies that come together and become ...

An artist's concept of a star's remnants forming a disk around a black hole. Illustration: NASA, ESA, STScI, Ralf Crawford (STScI) Astronomers have spotted an apparent supermassive black hole ...

Ever since general relativity pointed to the existence of black holes, the scientific community has been wary of one peculiar feature: the singularity at the center—a point, hidden behind the ...

The sneaky black hole betrayed its presence in a newly identified tidal disruption event (TDE) where a hapless star was ripped apart and swallowed in a spectacular burst of radiation. These ...

That is a black hole. There are a few defining characteristics for these objects. They tend to have an event horizon, the surface that separates them from the rest of the universe – once you ...

Researchers have finally confirmed that black holes spin. By watching the radio jet of the black hole at the center of the galaxy Messier 87, researchers were able to watch it tilt, a movement ...

In most cases, these newly arrived supermassive black holes would end up at the center of the galaxy and eventually merge with the central supermassive black hole. But note the phrasing there ...

At least, that’s the conclusion of an international team of researchers that applied geometric structures inspired by particle physics and string theory to the behavior of black holes when the ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

Measurements of wind in a luminous galactic core reveal dense pockets of gas — a finding that calls for a rethink of how black holes interact with their host galaxies. Read the paper ...
