Astronomers think they have established a new way to calculate the size of supermassive black holes: by studying the feeding patterns of these invisible giants.
A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light. Learn more about what black holes are and the latest news.
Concentric ripples in galactic dust clouds triggered by a powerful black-hole X-ray burst can be seen in a new image released by NASA.
A German X-ray mission is mapping the distribution of black holes and neutron stars in the Universe, having discovered over two million such new objects in less than two years since its launch.
New images obtained by the Event Horizon Telescope (EHT) reveal a powerful jet ejected from a supermassive black hole in unprecedented detail.
Theories that attempt to resolve the so-called black hole information paradox predict that black holes are much more complicated than general relativity suggests.
Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence.
A cluster composed of thousands of stars may dissolve to become a mob of dozens of black holes in a billion years.
Could gas escaping the gravitational grasp of supermassive black holes be forming "tsunamis" in space?
The "active galactic nucleus" phase of the supermassive black hole at the heart of the galaxy Arp 187 has apparently just ended.
After more than four years of exploring a menagerie of cosmic happenings through gravitational waves, scientists have finally spotted the third expected variety of collision — twice.
Physicists analyzed data from the first ever gravitational waves detected to prove Hawking's theory, and think that even more could be discovered from studying the ripples in space-time.
Scientists have found the earliest known "storm" generated by a supermassive black hole, a discovery that could shed considerable light on the coevolution of galaxies and their central black holes.
Astrophysicists dream of one day truly seeing a black hole merger, rather than merely painting its portrait based on how it affects surrounding matter.
Astronomers have apparently found the closest known black hole to Earth — a weirdly tiny object dubbed "The Unicorn" that lurks just 1,500 light-years from us.
Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.
A stunning new animation from NASA shows the entrancing dance of two monster black holes in orbit around each other.
