Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA’s James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for ...

Listening to the "ringing" produced by black holes after they collide and merge could allow scientists to test Einstein's ...

A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new ...

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) ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in the sky. But no one knows whether the ...

An unusually massive black hole in the very early universe may be a kind of exotic, star-less black hole first theorised by Stephen Hawking. In August, Boyuan Liu at the University of Cambridge and ...
