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

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

An international team, led by astronomers at the MIT Haystack Observatory, has obtained the closest views ever of what is believed to be a super-massive black hole at the center of the Milky Way galaxy. picked by AutumnLotus 1 month ago

In a distant galaxy, a star orbiting a massive central black hole strays too close to the insatiable giant and is torn apart. But before it can be devoured, the star lets out one last scream in a flare of light that slowly echoes across the galaxy. Astronomers on Earth pick up this faint call and use it to map the nucleus of the galaxy from which it emanated. picked by AutumnLotus 5 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 9 months ago

US astronomers have discovered the biggest black hole orbiting a star 1.8 million light-years from Earth in the constellation Cassiopeia, with a record-setting mass of 24 to 33 times that of our Sun. The massive newcomer beats the previous stellar-mass black hole discovered October 17 in the M33 galaxy that has 16 times the mass of our Sun. picked by AutumnLotus 12 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 12 months ago

A colossal black hole has been spotted exiting its home galaxy, kicked out after a huge cosmic merger took place.

The event, seen for the first time, was announced today. picked by AutumnLotus 6 months 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 5 months ago

Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy’s central black hole let loose a powerful flare three centuries ago. picked by AutumnLotus 6 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

A dramatic new Chandra image of the nearby galaxy Centaurus A provides one of the best views to date of the effects of an active supermassive black hole. Opposing jets of high-energy particles can be seen extending to the outer reaches of the galaxy, and numerous smaller black holes in binary star systems are also visible. picked by AutumnLotus 9 months ago

Astronomers have discovered a super massive black hole about 13 billion light years away from earth. This means it was formed only one billion years after the big bang, when the universe was merely an infant. Cool. picked by Moe 1 year ago

Attempt to prohibit (from a court in Hawaii) attempts to make a mini black hole at CERN in Europe.

A black hole's intense gravitational field can cause individual photons of light to go into orbit around it temporarily, new calculations suggest. That means that photons from a single burst of light that explodes near the black hole could orbit the hole for different amounts of time before escaping into space, making the black hole appear to flash like a strobe light. picked by AutumnLotus 9 months ago

The date of 2008.03.19 marked the brightest ever cosmic explosion observed from the Earth. The outburst denoted as GRB 080319B was probably the death of a massive star leading to the creation of a black hole. Watch video here. picked by AutumnLotus 7 months ago
