Astronomers found a massive black hole that spent ages in a "quiet" phase when everything around it in the early universe ...

In 1974, Stephen Hawking put forward an intriguing idea: Using the principles of quantum physics, he predicted that even though nothing is supposed to escape a black hole's event horizon ...

Strange vibrations emanating from a supermassive black hole appear to be growing more frequent and they could be caused by a white dwarf star orbiting perilously close to its event horizon.

A flat public servant wages forecast may have made sense under a stingy Coalition, but it makes no sense under a Labor ...

We do not know what dark energy is but its existence allows astronomers to explain so many features of the universe. A new hypothesis suggests quite a peculiar source of this energy: black holes.

In this case, the sheer size of the dormant black hole suggests that our standard models may not fully explain how holes of this magnitude form and grow. “It’s possible that black holes are ...
