In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's accretion disk,…
Researchers at the University of Helsinki have advanced our understanding of black holes using supercomputer simulations, revealing how magnetic fields cause turbulence that heats plasma and produces X-ray radiation observable from Earth.…

A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon.
Supermassive black holes that shred and devour stars throw them up like a "bad curry" and cover themselves in the wreckage, sick new simulations reveal.
Stars that wander too close to supermassive black holes may be violently undone in a process called "spaghettification." New simulations provide the most detailed look ever at the gory interaction.
The precarious state of Barcelona’s finances is a problem the club and Spanish football in its entirety seems determined to ignore most of the time. However, when the club is forced to give away one of its highest-earning players, it can…
