Artificial black holes made with metamaterials
While our direct knowledge of black holes in the universe is limited to what we can observe from thousands or millions of light years away, a team of Chinese physicists has proposed a simple way to design an artificial electromagnetic (EM) black hole in the laboratory. View More (2010-11-16)
Black hole surprise in ancient star cluster
Astronomers have made the unexpected discovery of two black holes inside an ancient cluster of stars in our galaxy, the Milky Way. View More (2012-10-04)
Cookie cutter in the sky
Black holes can now be thought of as donut holes. The shape of material around black holes has been seen for the first time: an analysis of over 200 active galactic nuclei-cores of galaxies powered by disks of hot material feeding a super-massive black hole-shows that all have a consistent, ordered physical structure that seems to be independent of the black hole's size.

Planets smashed into dust near supermassive black holes
Fat doughnut-shaped dust shrouds that obscure about half of supermassive black holes could be the result of high speed crashes between planets and asteroids, according to a new theory from an international team of astronomers. View More (2011-10-31)
Movement of black holes powers the universe's brightest lights
Whether on their own or orbiting as a pair, black holes don't typically sit still. View More (2011-07-21)
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)
Answers to black hole evolution beyond the horizon?
One of the most important predictions of Einstein's theory of General Relativity is the existence of black holes. The dynamics of these systems are not yet fully understood, but researchers from Queen Mary, University of London have now provided a rigorous way of determining the evolutionary stage of a black hole by analysing the region outside where matter cannot escape, the event horizon.

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 affects galaxy growth. View More (2008-01-11)
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)
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 precise, astronomers do not detect black holes. But they do detect the phenomena that can only be... View More (2003-11-27)
Sleeping Giants Discovered
Astronomers recently discovered the most massive black holes to date. Found in two separate nearby galaxies roughly 300 million light years away from Earth, each black hole has a mass equivalent to 10 billion suns. View More (2011-12-07)

Simulating black hole radiation with lasers
A team of Italian scientists has fired a laser beam into a hunk of glass to create what they believe is an optical analogue of the Hawking radiation that many physicists expect is emitted by black holes. View More (2010-11-09)
Record-breaking black holes discovered, U of T astronomer on international team
An international team of astronomers has discovered two gigantic black holes with masses about 10 billion times the mass of our sun. These black holes have a mass more than 50 per cent greater than any other previously measured. View More (2011-12-06)
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)
Curtains down for the black hole firewall paradox
Research by scientists at the University of York has revealed new insights into the life and death of black holes. View More (2013-03-07)
Gas promises bumper black hole 'weigh-in'
A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies. View More (2013-01-31)
