When scientists discovered an enormous black hole thousands of light-years from where it ought to be in space, they knew they ...

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...

Science fiction is full of amazing space phenomena. Some of those phenomena have gone from theory to reality — like black holes and pulsars. But what about wormholes? These portals through space are ...

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of times ...

Seven strangely-behaving stars in the Milky Way's Omega Centauri cluster may be under the influence of an extremely rare type of black hole, new research suggests. Using the James Webb Space Telescope ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...

Scientists detected the merger of two extremely massive black holes. This merger created the most massive black hole ever observed through gravitational waves. The black holes' size and rapid spin ...
