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 11 months ago

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 dork 1 year 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

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 10 months 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

Black holes can be secretive about their past, but now there may be an easy way to tell if a monster black hole was once a pair that got cosy and fused together. picked by AutumnLotus 2 months ago

Right now, the colour black, or “Kuro” in Japanese, is surprisingly enjoying widespread popularity in Japan. A trend so strong that we could even find an oh-so-hip black toilet paper. picked by muppet 12 months ago

The most massive black hole in the universe tips the cosmic scales at 18 billion times more massive than the sun, astronomers suggest today at a meeting of the American Astronomical Society. Even though researchers suggested black holes up to this mass might exist in quasars, this is the first direct confirmation of such a behemoth. picked by AutumnLotus 6 months 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 3 months ago

A stellar black hole much more massive than theory predicts is possible has astronomers puzzled. The newly weighed black hole is 16 solar masses. It orbits a companion star in the spiral galaxy Messier 33, located 2.7 million light-years from Earth. Together they make up the system known as M33 X-7. picked by AutumnLotus 9 months ago

We are close to seeing the true blackness of a black hole. Astronomers have detected radio emission coming from within 30 million kilometres of the dark object, thought to be a colossal black hole, that lies at the centre of the galaxy. Includes video. picked by AutumnLotus 6 months ago

Hundreds of undetected black holes, each with a mass thousands of times greater than the Sun, might be stealthily roving our galaxy, ready to devour anything that crosses their paths. picked by AutumnLotus 6 months ago

A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance. picked by AutumnLotus 5 months ago
