While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

A team of US astronomers led by Kailash Sahu said they have finally discovered the first isolated stellar-mass black hole ...

Most people know that black holes are kind of scary. Admittedly, that's true, but black holes are so much more than that.

One of the most powerful objects in the universe is a radio quasar — a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its ...

You can imagine the black hole as a rotating sphere, and the accretion disk as a disk with a hole in the center. The black hole sits in that center hole and rotates one way, while the accretion disk ...

Physicists have built the first ever black hole bomb, a long-theorised phenomenon where energy is boosted by a black hole and trapped by surrounding mirrors until an explosion occurs. Thankfully ...

In 2018 astronomers at MIT and elsewhere observed previously unseen behavior from a black hole known as 1ES 1927+654, which ...

"We want to understand how these galaxies are forming stars, how many stars they’re forming, and especially how the black ...

You can imagine the black hole as a rotating sphere, and the accretion disk as a disk with a hole in the center. The black hole sits in that center hole and rotates one way, while the accretion ...

Earlier black hole models assumed perfect symmetries not found in nature, positing, for example, that a star was a perfect sphere before collapsing into a black hole, or that it had no net ...
