New research can help explain how black holes can produce powerful jets.

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.
Another reason you don’t want to get too close to a black hole is because of something we call ‘spaghettification’. If this happened to Earth it would be… unpleasant.
If you got too close to a black hole, it would suck you in and you'd never be able to escape, even if you were travelling at the speed of light.
This point of no return is called the event horizon.

Scientists turned Earth into one giant telescope to capture the uncapturable.

Who wouldn't want to travel in time, glimpsing the dinosaurs or peeking at humans 2,000 years from now? Now physicists have designed a time machine that seems deceptively simple.
We don’t know what the black hole at the centre of the Milky Way will look like.
The first ever picture of the Milky Way's black hole is expected to be a bright crescent shape rather than a disk.
“Infinite” is where we get to when we reach the limits of our understanding.
Peruse the astrophysical literature and you could be forgiven for thinking black holes exist. But do they really? What makes a black hole special is its event horizon: a no-return gateway to an unknowable…
