While sifting out signatures of supernova remnants, a high-schooler stumbled upon the afterglow of a dormant black hole. It ...

It will take well over 10^100 years for even the smallest known black holes to die. If the KM3NeT neutrino is due to an ...

A tiny black hole may have exploded, firing a powerful neutrino at Earth — possibly proving Stephen Hawking’s theory after 50 ...

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 ...

The universe is ballooning outward at an ever-faster clip under the power of an unknown force dubbed dark energy. One of the ...

Their novel method, which will make it easier for the mass and the spin of black holes to be measured, ... Dance of Electrons Measured in the Glow from Exploding Neutron-Stars Nov. 4, 2024 — The ...

"The higher the spin, the more energy the black hole can release." Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Some become neutron stars while very massive ones become black holes. An exploding supernova throws hot gas into space. Depending on the mass at the start of its life, a supernova will leave ...

New research suggests it could be evidence that Stephen Hawking was right about the nature of black holes and the early universe.

This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or astronomers have been measuring the universe's expansion incorrectly ...
