New research shows that black holes are not the ultimate destroyers that are often portrayed in popular culture. Instead, warm gas escaping from the clutches of enormous black holes could be one source of the chemical elements that make life possible. picked by AutumnLotus 1 year ago

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all. picked by 2manyusernames 1 year ago

Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. Finding such an unmasked form of what physicists term a singularity "would shock the foundation of general relativity." picked by AutumnLotus 1 year ago

Astronomers can't see black holes. And they definitely can't go out and grab a piece of one to measure its mass.

So how do they weigh them? picked by AutumnLotus 1 year ago

Legions of tiny black holes created during the big bang may lurk at the centre of the galaxy, creating a prodigious antimatter factory, a new study suggests. The work could explain where the Milky Way's antimatter comes from – one of the biggest mysteries in astrophysics. picked by AutumnLotus 9 months ago

According to two astrophysicists from Paris Observatory, the fate of stars that venture too close to massive black holes could be even more violent than previously believed. Not only are they crushed by the black hole's huge gravity, but the process can also trigger a nuclear explosion that tears the star apart from within. picked by AutumnLotus 5 months ago

Spitzer Space Telescopes show that the vicinities around the black holes could be backing up with excess matter - the black holes just can’t consume it fast enough to clear the space. When this happens, the matter heats up, and releases a tremendous amount of energy. picked by 2manyusernames 2 years ago

The incredible amount of energy given off across the entire electromagnetic spectrum during a gamma-ray burst is what Jonathan Grindlay of the Harvard-Smithsonian Center for Astrophysics calls "the birth pangs of a black hole. This is the scream." picked by AutumnLotus 1 month ago

Black holes can't be seen, but they're detected by noting their effects on stars or gas around them. They're so dense that nothing, including light, escapes them. Only two classes of black holes are firmly established to exist: Stellar black holes typically weigh a few times the mass of the sun; supermassive black holes are loaded with millions or billions of solar masses. picked by AutumnLotus 6 months ago

A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth. picked by AutumnLotus 9 months ago

Hundreds of "missing" black holes have been found lurking in dusty galaxies billions of light-years away. The finding is the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths constructing supermassive black holes at their cores. picked by AutumnLotus 12 months ago

The most energetic particles in the universe likely come from enormous black holes nestled in the restless hearts of traumatized galaxies, scientists say. Where these cosmic "bullets" originated has been a source of much speculation, with scientists proposing everything from gamma ray bursts to decaying dark matter. picked by AutumnLotus 11 months ago

Supermassive black holes could leave behind long-lasting infrared afterglows visible to current instruments when they merge, a new study says. If so, scientists could find signs of these mergers much sooner than expected. picked by AutumnLotus 7 months ago

What is the magic "X factor" that determines which stars become the biggest and brightest in the universe? The answer, new calculations suggest, is how dense their parent gas clouds are. Denser clouds heat up more evenly, preventing the clouds from fragmenting into lots of tiny stars and allowing one or two big stars to form instead. picked by AutumnLotus 8 months ago
