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.
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.
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.
If you could journey through the cosmos' most monstrous objects, what tales — if any — would you be able to tell?
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.
The supermassive black hole at the heart of the galaxy M87 is coming into sharper and sharper focus.
NASA's long-serving Hubble Space Telescope is seeing double after detecting two rare pairs of quasars nestled within galactic collisions that occurred 10 billion years ago.
Evidence of collisions between black holes and neutron stars suggests dark matter might consist of concentrations of primordial black holes.
Light coming from an explosion in the early universe has illuminated a black hole that astronomers think could expand their understanding of how the celestial objects form.
Astrophysicist Andrea Ghez has spent her scientific career peering at the center of the Milky Way, trying to see the invisible.
A supermassive black hole is racing across the universe at 110,000 mph (177,000 km/h), and the astronomers who spotted it don't know why.
A space telescope might have spotted one of the most distant supermassive black holes spurting an X-ray jet.
The hypothetical Planet Nine may not be a planet but rather a small black hole that might be detectable from the theoretical radiation emitted from its edge, so-called Hawking radiation.
A newly discovered quasar from the early universe is the most distant found to date that's shooting out powerful radio jets.
