Black Hole

Astronomers have found the most extreme example yet of a black hole outweighing its own galaxy, and it may be hiding clues to how the supermassive black holes seen today formed in the early universe. In a new study, astronomers directly measured the mass of a black hole sitting in…

Gigantic, ancient black hole threatens to upend cosmic history Debate still swirls around the nature of “little red dots,” black holes glimpsed in the early universe by the James Webb Space Telescope. A controversial new weigh-in may settle the matter By Joseph Howlett edited by Lee Billings An artist’s conception…

In 1993, Canadian physicist Matthew Choptuik demonstrated black holes may emerge spontaneously from critical collapse, during which spacetime curvatures organize themselves into a defined, repeating crystal-like pattern. But researchers weren’t quite able to describe this nicely in formulaic language—until now. A team of theoretical physicists say it’s found the long-sought…

The Late Show With Stephen Colbert is officially a late show, as in it’s no longer with us. Its last Questionert has been answered; its final rescue dog has been rescued; its ultimate guest, Sir Paul McCartney, has left the building. Colbert filled his 80-minute finale with the same thoughtfulness,…

(Image credit: Robert Lea (created with Canva)) New research suggests that supermassive black holes that existed before the cosmos was 1 billion years old may have formed with a helping hand from dark matter, the universe's most…

The strong stellar wind from the supergiant starpushes the jets launched by the black hole away from the star. (Image credit: International Centre for Radio Astronomy Research(ICRAR)) Astronomers watched as jets blasting from a black hole cannibalized a blue supergiant companion star. Data from the Square Kilometre Array Observatory (SKA)…

New research by Professor Enrique Gaztañaga from the University of Portsmouth and the Institute of Space Sciences in Barcelona suggests some black holes formed before the Big Bang and survived a cosmic ‘bounce,’ potentially explaining dark matter, gravitational-wave backgrounds, and the early growth of supermassive black holes and galaxies. Gaztañaga…

Researchers have taken a major step toward understanding how black holes influence the universe by directly measuring the power of their jets. Using a network of radio telescopes spread across the globe, a team led by Curtin University captured detailed images that reveal just how energetic these jets can be.…
