Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

When NASA detects two black holes colliding, the cosmos is in a state of chaos. Black holes lie at the centre of most ...

Discover how researchers found a bizarre black hole feeding at an exceptional rate, challenging theories on black hole growth.

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

A strange black hole is making scientists scratch their heads.

In an article published in Physical Review Letters on Thursday, scientists carried out an innovative study testing the ...

X-ray spectroscopy of gas deep in the potential well of the black hole, where the effects of strong gravity are important, allows us to probe the properties of the black hole itself. We numerically ...

Space-time may not be continuous but instead made up of many discrete bits – and we may be able to see their effects near the edges of unusually bright black holes ...
