Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.

The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass ...

The size and spin of black holes can reveal how they are formed and where they were born. You can tell a lot about a human being's ancestry from their general characteristics. A child can have ...

Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes—those up to billions of times heavier than the sun. The new survey is unique because it was as ...

Jets from black holes trigger cooling in the hot gas, causing it to condense into warm filaments. These filaments then flow toward the black hole, feeding it, and the cycle repeats. Brightness ...

One supermassive black hole has kept astronomers glued to their scopes for the last several years. First came a surprise disappearance, and now, a precarious spinning act. The black hole in ...

It's no secret that black holes are some of the weirdest objects in space. Their disks are fluffy like cake, and diving into one is both interesting and terrifying. Now, a group of astronomers ...

The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary research Sara Hashemi Daily Correspondent An artist’s concept of a white ...

An undiscovered population of ancient black holes may be lurking throughout the universe. These bottomless cosmic pits would have a lot in common with more familiar black holes; in some cases ...
