While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared.

The infant universe's population of huge black holes could owe itself to ultralight dark matter, scientists say.

Astronomers have used space-based telescopes, including NASA's Swift X-ray observatory, to watch a monster black hole spring to life with powerful X-ray eruptions.

In the early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime, new research suggests. This makes them an interesting candidate for dark matter.

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

A hidden monster black hole in the Large Magellanic Cloud fired runaway stars at the Milky Way at millions of miles per hour.

Scientists have discovered more about the process that causes black holes to "leak" energy to their surroundings, finding the faster they spin, the more energy is extracted.

Gamma rays detected by NASA's Fermi spacecraft indicate that microquasars are powered by small black holes slowly devouring stars. They pack quite a punch, bombarding Earth with cosmic rays.

Using a revolutionary dark energy camera, astronomers have discovered the largest haul of "missing link" intermediate-mass black holes ever seen, but there should have been more.

Using the James Webb Space Telescope, astronomers have taken a detailed look at the supermassive black hole at the heart of the Milky Way, Sgr A*, finding it endlessly blowing bubbles.
