Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds.
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.
A team of scientists now suggests black holes could reach what they call "stupendously large" sizes, each harboring the mass of 100 billion suns or more.
For black holes, a collision doesn't have to be a once-in-a-lifetime experience, new research suggests.
A cosmic gas cloud has a mysterious gamma-ray "heartbeat" that appears to be in sync with a neighboring black hole.
Astronomers might detect black holes falling into wormholes via ripples in space and time called gravitational waves, a new study finds.
Tens of thousands of planets like Earth and Neptune might orbit the giant black hole at the center of the Milky Way.
Over two dozen misidentified supermassive black holes have finally been revealed in a new, sky-scanning study.
What does it mean when a black hole suddenly stops gobbling up gas completely — and then just as suddenly starts again, hungrier than ever?
A coming sky survey will help test a wild idea — that a grapefruit-sized black hole lurks undiscovered in the outer solar system.
Astronomers have found a way to pinpoint our solar system's center of mass to within a mere 330 feet (100 meters), a recent study reports.
Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.
It's right there in the name: black holes aren't supposed to produce flashes of light. But scientists think that last year, they spotted black holes doing just that.
Astrophysicists have spotted the strangest gravitational-wave signal yet, an observation that could force scientists to rewrite what they know about the cosmos.
A black hole shooting out gassy material at nearly the speed of light has been caught on video by NASA's Chandra X-ray Observatory.
NASA's Hubble Space Telescope is further probing the remnants of a massive space explosion visible from Earth 3.5 million years ago.
A new virtual reality experience lets you fly closely, but safely, towards the supermassive black hole embedded in the heart of our galaxy, the Milky Way.
