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)

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)

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)

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)

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)

Yale Astronomer Discovers Upper Mass Limit for Black Holes
here appears to be an upper limit to how big the universe's most massive black holes can get, according to new research led by a Yale University astrophysicist.   view more (2008-09-12)

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)

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)

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)

Ultrafast star escapes black hole
Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur.   view more (2006-10-05)

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)

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)

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)

Chandra catches 'piranha' black holes
Supermassive black holes have been discovered to grow more rapidly in young galaxy clusters, according to new results from NASA's Chandra X-ray Observatory.   view more (2007-07-25)

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)

Galaxy may hold hundreds of rogue black holes
If the latest simulation of what happens when black holes merge is correct, there could be hundreds of rogue black holes, each weighing several thousand times the mass of the sun, roaming around the Milky Way galaxy.   view more (2008-01-10)

Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust.   view more (2005-08-08)

UCSB professor's paper on safety of large hadron collider to be published in Physical Review D
Particle colliders creating black holes that could devour the Earth. Sounds like a great Hollywood script.   view more (2008-06-30)

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)

Black holes have simple feeding habits
The biggest black holes may feed just like the smallest ones, according to data from NASA's Chandra X-ray Observatory and ground-based telescopes. This discovery supports the implication of Einstein's relativity theory that black holes of all sizes have similar properties, and will be useful for... view more (2008-06-19)

NASA'S Chandra finds black holes stirring up galaxies
Black holes are creating havoc in unsuspected places, according to a new study of images of elliptical galaxies made by NASA's Chandra X-ray Observatory.   view more (2006-01-11)

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)

LHC switch-on fears are completely unfounded
A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday next week, poses no threat to mankind. Nature's own cosmic rays regularly produce more powerful particle collisions than... view more (2008-09-08)
