A Very Massive Stellar Black Hole in the Milky Way Galaxy
VLT ISAAC Uncovers an Enigmatic Microquasar   view more (2001-11-27)

Biggest 'small' black hole discovered
Discovery of the largest example of a "small" black hole - one formed from the collapse of a single massive star at the end of its lifetime - has led scientists to revaluate of how black holes come into being, according to a report in Nature.   view more (2007-10-22)

How to Make A Black Hole Choke

ESA finds a black-hole flywheel in the Milky Way
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldn`t. You`d be dragged around at high speed as if you were riding on a giant flywheel. In reality, gas falling into the black... view more (2002-04-26)

No matter their size black holes 'feed' in the same way
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.   view more (2006-12-07)

UI researchers discover star orbiting a 'medium-sized' black hole
University of Iowa researchers have found a star orbiting a "medium-sized" black hole - about 1,000 times more massive than the sun - in the nearby starburst galaxy M82, a development that may help explain how medium-sized black holes form and evolve.   view more (2006-01-06)

The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be... view more (2003-11-27)

A hidden twist in the black hole information paradox
Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be 'hidden' in conventional ways, or in Braunstein's words, "quantum... view more (2007-02-28)

Flares illuminate the secret life of a quiescent black hole
Astronomers probing the intimate details of apparently quiescent stellar black holes have discovered that in reality they are dynamic, lively places, subject to flares that briefly illuminate the whole of the gas disc around the black hole. Their observations are helping to build up a picture of... view more (2002-04-04)

NASA's Chandra finds black holes are 'green'
Black holes are the most fuel efficient engines in the Universe, according to a new study using NASA's Chandra X-ray Observatory.   view more (2006-04-25)

A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory.   view more (2008-07-17)

Quasar light variability linked to black hole mass
Quasars are some of the most luminous and distant objects in the universe - and appear to have something in common with ordinary light bulbs.   view more (2007-01-09)

Study finds two supermassive black holes spiraling toward collision
A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars.   view more (2006-04-06)

Chandra data reveal rapidly whirling black holes
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... view more (2008-01-11)

TAU Scientists Help Discover the Most Massive Stellar Black Hole Ever Found
An international team, including astronomers from Tel Aviv University, has uncovered the most massive stellar black hole found to date in a binary system.   view more (2007-11-09)

Music of the black holes: they all play the same tune
Astronomers at the University of Southampton have uncovered a remarkable connection between the monstrous black holes residing at the hearts of distant galaxies and their comparatively tiny cousins which inhabit star systems in our own Milky Way: they are playing the same tunes. Dr Phil Uttley... view more (2002-04-04)

Massive Black Hole Smashes Record
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star.   view more (2007-10-31)

RIT study predicts how fast a black hole can be booted from a galaxy
Scientists have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger.   view more (2007-05-31)

Dancing around the Black Hole
ISAAC Finds "Cool" Young Stellar Systems at the Centres of Active Galaxies Supermassive Black Holes are present at the centres of many galaxies, some weighing hundreds of millions times more than the Sun. These extremely dense objects cannot be observed directly, but violently moving gas clouds and... view more (2001-08-14)

Scientists find the reason behind black holes' light shows
A team of astronomers led by the University of Michigan may know how black holes are lighting up the Universe.   view more (2006-06-22)

MIT: Spinning black hole leaves dent in space-time
MIT scientists and colleagues have found a black hole that has chiseled a remarkably stable indentation in the fabric of space and time, like a dimple in one's favorite spot on the sofa.   view more (2006-01-11)

New technique for 'weighing' black holes
ESA's XMM-Newton has helped to find evidence for the existence of controversial Intermediate Mass Black Holes. Scientists used a new, recently proven method for determining the mass of black holes.   view more (2007-05-17)

Polarizing filter allows astronomers to see disks surrounding black holes
For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be.   view more (2008-07-24)

Milky Way's Giant Black Hole Awoke from Slumber 300 Years 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.   view more (2008-04-16)
