At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions ...

Astronomers have witnessed a distant supermassive black hole devouring its surrounding matter so rapidly that it is "burping" out excess mass at nearly a third of the speed of light.

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.

New research suggests that black holes may actually be "frozen stars," bizarre quantum objects that lack a singularity and an event horizon, potentially solving some of the biggest paradoxes in ...

Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of ...

The biggest problem with the Hawking radiation emitted by our Universe's black holes is the power: the highest-flux black hole emits just 10 -29 W of power, an incredibly small amount.

It is extremely difficult to observe the radiation that is thought to be emitted by black holes. The properties of this radiation have now been analysed using an analogue black hole comprising a ...

Do-it-yourself event horizon Hard to recreate in the lab You might expect black holes to be, well, black, but several decades ago Stephen Hawking calculated that they should emit light. Now, for ...
