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,…
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…
The "deaths" of galaxies are caused by their central supermassive black holes, and the "smoking gun" evidence of this connection takes an unexpected form.
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 chaotic movements of magnetic fields…
Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from black hole surroundings. The radiation originates from the combined effect of the chaotic…
New York Gov. Kathy Hocul's attempts at zingers and her overall performance received brutal reviews at the first night of the Democratic National Convention.
Monash University astronomers have contributed to a breakthrough in understanding the dramatic fate of stars that wander too close to supermassive black holes at the centers of galaxies.
