The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth&rsquo ...

Runaway black holes have moved from theoretical oddity to observed reality, and the picture they paint is as unsettling as it is awe inspiring. Instead of sitting quietly at galactic centers, some of ...

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) ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking’s area theorem and Einstein’s ringdown behavior. The findings also provide ...
