Powerful black holes might grow up in bustling galactic neighborhoods

An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.

We found some strange radio sources in a distant galaxy cluster. They’re making us rethink what we thought we knew.

One of the objects is a ‘fossil’ radio source – a leftover from the death of a supermassive black hole that once shot out huge jets of plasma.

Some black holes are anything but black – and we’ve found more than 75,000 of the brightest ones

Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.

Could a human enter a black hole to study it?

If you are a sci-fi junkie you’ve probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you’d fare all depends on the type of black hole.
