The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

The Porphyrion jets, which come from a supermassive black hole about 7.5 billion light-years from Earth, were found thanks to radio images from the International LOFAR Telescope, which revealed ...

Scientists may have cracked one of the biggest mysteries in space science, determining that supermassive black holes bent the laws of physics to grow to their huge sizes.

Either way, it appears M87's supermassive black hole might be behind the unusually high number of neighboring novae—the exact mechanism of its work is just unclear. Tagged In ...

Supermassive black holes grow primarily in two ways. They can consume gas from their host galaxies in a process called accretion, and they can also merge with each other when two galaxies collide.

Sagittarius A*—the supermassive black hole at the heart of the Milky Way—is presently in a dormant state, although astronomers believe that it did have large-scale radio jets in the past.

And, once a supermassive black hole gets big enough, its event horizon is so far out that stars can pass through it before they get disrupted, and all the energetic release would take place inside ...

The Large Magellanic Cloud, a close neighbor to the Milky Way, may house a giant black hole. It's the closest supermassive black hole outside of our galaxy.

Scientists clear up how supermassive black holes came to be (hint: big seeds) The origin of supermassive black holes has stumped scientist for a long time. They now have the answer to this ...
