When scientists discovered an enormous black hole thousands of light-years from where it ought to be in space, they knew they had a cosmic oddity on their hands. NASA's Hubble Spa

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely

A new study may visually solve an enduring mystery about a bright object that's been studied since the 19th century

By zeroing in on the infrared scale, researchers offer details of the black hole jet stream in faraway galaxy M87.

By developing a new theoretical relation describing just how compact neutron stars — which are the remnants of massive stars that have gone supernova — can get, researchers have found a way to test the properties of nuclear physics under very extreme conditions.

It’s possible that these objects might be the primordial beginnings of the supermassive black holes found in the centers of most galaxies.

First-ever image of two black holes captured orbiting each other, confirming a decades-old theory using a powerful radio telescope.

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the initial destruction,

For the first time, astronomers have detected intense, fast-changing radio signals from a tidal disruption event, dubbed AT2024tvd, located outside its galaxy's core. Now, astronomers are trying to understand what the black hole is doing 2,
