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

The two black holes tracked by the Event Horizon Telescope were both of this type. Sagittarius A* (Sag A* for short) is smack in the middle of the Milky Way, some 26,000 light years from Earth.

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 ...

In this new study, researchers applied quantum gravity to the interior of a black hole. They focused on a specific type of ...

In the most detailed look at that black hole ever undertaken ... paper published in The Astrophysical Journal Letters, these types of flares usually burst out of accretion disks, or swirling ...

Scientists have discovered key conditions needed for a stellar black hole to create plasma jets. Their findings show that when superheated gas material experiences a rapid shrinkage towards the black ...

Black holes are bounded by outer barriers called event horizons that prevent us from ever viewing their interiors or their hearts, singularities at which all known laws of physics collapse.

Unlike a planet or star, black holes don't have surfaces. Instead, they have a boundary called an "event horizon," or a point of no return. If anything swoops too close, it will fall in ...

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy ...
