A ripple in spacetime from two colliding black holes may hold the first direct fingerprint of dark matter — and detectors just caught the signal
On July 28, 2019, the LIGO and Virgo gravitational-wave observatories recorded a brief shudder in spacetime: two black holes, ...
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 ...
Some black holes could have tamer origins—in the folds of unusual "spacetime crystals" that researchers finally managed to ...
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 ...
