A Hungry Quasar Caught in the Act
The VLT Secures Spectacular Image of Distant Gravitational Interaction A new image of a distant quasar (the luminous core of an "active" galaxy) shows that it is engaged in a gravitational battle with its neighbouring galaxies. It also provides information on how supermassive black holes present in the center of quasars are fed. Using the FORS2 multi-mode instrument at the ESO 8.2-m VLT KUEYEN... View More (2001-05-31)
Extremely rare triple quasar found
For only the second time in history, a team of scientists--including Carnegie's Michele Fumagalli--have discovered an extremely rare triple quasar system. Their work is published by Monthly Notices of the Royal Astronomical Society. View More (2013-03-12)
Astronomers using NASA's Hubble discover quasars acting as gravitational lenses
Astronomers using NASA's Hubble Space Telescope have found several examples of galaxies containing quasars, which act as gravitational lenses, amplifying and distorting images of galaxies aligned behind them. View More (2012-03-16)
Astronomers discover an unusual cosmic lens
Astronomers at the California Institute of Technology (Caltech) and Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have discovered the first known case of a distant galaxy being magnified by a quasar acting as a gravitational lens. View More (2010-07-16)
Earliest watery black hole discovered
Water really is everywhere. A team of astronomers have found the largest and farthest reservoir of water ever detected in the universe-discovered in the central regions of a distant quasar. View More (2011-07-25)
Virginia Tech scientists discover record-breaking black hole energy blast
Virginia Tech physics researchers have discovered a quasar with the most energetic outflow ever, a finding that may answer questions about how the mass of a galaxy is linked to its central black hole mass and why there are so few large galaxies in the universe. View More (2012-11-29)
Astronomers discover universe's most distant quasar
A scientist at The University of Nottingham is part of a team of astronomers which has discovered the most distant quasar to date - a development that could help further our understanding of a universe still in its infancy following the Big Bang. View More (2011-06-30)
NASA's Chandra Finds Evidence for Quasar Ignition
New data from NASA's Chandra X-ray Observatory may provide clues to how quasars "turn on." View More (2006-03-24)
Black hole in search of a home
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. View More (2005-09-15)
Is the Universe older than expected?
An analysis of 13.5 thousand million-year-old X-rays, captured by ESA's XMM-Newton satellite, has shown that either the Universe may be older than astronomers had thought or that mysterious, undiscovered 'iron factories' litter the early Universe. ESA`s Norbert Schartel and colleagues from the Max-Planck-Institut für extraterrestrische Physik,Germany, found more iron than anyone thought... View More (2002-07-10)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is some 13 billion light years away, and we are seeing it when the universe was very young - only 900... View More (2003-04-02)
New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses, which are seen when a galaxy bends the light from a distant quasar to form several images of the same...

Galaxy 'Hunting' Made Easy
Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits a first-class instrument, represents a major breakthrough in the field of galaxy 'hunting'. View More (2007-09-17)
Quasars: Mileposts marking the universe's expansion
Scientists can't travel deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the west. View More (2012-09-19)
Cosmic engines surprise XMM-Newton
XMM-Newton has been surprised by a rare type of galaxy, from which it has detected a higher number of X-rays than thought possible. The observation gives new insight into the powerful processes shaping galaxies during their formation and evolution. View More (2008-04-08)
Hubble zooms in on a space oddity
A strange, glowing green cloud of gas that has mystified astronomers since its discovery in 2007 has been studied by Hubble. View More (2011-01-11)
Cosmic curiosity reveals ghostly glow of dead quasar
While sorting through hundreds of galaxy images as part of the Galaxy Zoo citizen science project two years ago, Dutch schoolteacher and volunteer astronomer Hanny van Arkel stumbled upon a strange-looking object that baffled professional astronomers. View More (2010-11-04)
RIT Study Confirms Supermassive Black Holes Produce Powerful Galaxy-Shaping Winds
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. View More (2007-11-01)
When the first stars blinked on
As far back in time as astronomers have been able to see, the universe has had some trace of heavy elements, such as carbon and oxygen. View More (2012-12-06)
Quasars help trace ancestors of giant elliptical galaxies
By using the Hubble Space Telescope (HST) as a `time machine`, astronomers from the Universities of Edinburgh and Oxford in the UK and the Space Telescope Science Institute (STScI) in Baltimore in the USA have been able to trace back the history of massive elliptical galaxies. They have found that galaxies of this kind, which still exist today, were already luminous families of stars about 10... View More (2002-04-04)
