On July 28, 2019, the LIGO and Virgo gravitational-wave observatories recorded a brief shudder in spacetime: two black holes, ...

Scientists have developed a new technique that could turn black hole collisions into cosmic detectors for dark matter, ...

Some black holes could have tamer origins—in the folds of unusual "spacetime crystals" that researchers finally managed to ...

Size comparison of the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration: M87*, at the heart of the galaxy Messier 87, and Sagittarius A* (Sgr A*), at the centre of the Milky ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around it—or the other way around—is still a matter of some debate, but we know ...

A study in Nature finds that black holes in the early Universe go through short periods of ultra-fast growth, followed by long periods of dormancy. Scientists have spotted a massive black hole in the ...
