Powerful Nearby Supernova Caught By Web
One of the nearest supernovas in the last 25 years has been identified over a decade after it exploded. This result was made possible by combining data from the vast online archives from many of the world's premier telescopes. view more (2008-09-26)
e-Science, fundamental physics and the GRID
Research into e-Science reached a milestone in the UK today [Thursday 25 April] when Gordon Brown, The Chancellor of the Exchequer, opened The National e-Science Centre in Scotland. The centre, run jointly by the Universities of Glasgow and Edinburgh, will provide a focal point for the UK`s involvement in e-Science initiatives and integrate... view more... (2002-04-25)
NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. view more (2006-08-22)
Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous burst of star formation. view more (2008-10-21)
Another bar in the Bulge
Using 2MASS data, Christophe Alard (astronomer at Paris Observatory) has reconstructed a map of the projected density of the old stellar population of the Galactic Bulge region. By making a combination of the H and K photometric bands, it is possible to overcome the effect of reddening, and thus penetrate the inner structure of the Galactic Bulge. view more (2001-11-21)
A Window towards the Distant Universe
The Osservatorio Astronomico Capodimonte Deep Field (OACDF) is a multi-colour imaging survey project that is opening a new window towards the distant universe. It is conducted with the ESO Wide Field Imager (WFI), a 67-million pixel advanced camera attached to the MPG/ESO 2.2-m telescope at the La Silla Observatory (Chile). As a pilot project at... view more... (2001-04-11)
Suzaku Snaps First Complete X-ray View of a Galaxy Cluster
The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. view more (2009-05-29)
Storm clouds over Titan
Taking advantage of advanced techniques to correct distortions caused by Earth's atmosphere, astronomers used the NSF-supported Gemini Observatory to capture the first images of clouds over the tropics of Titan, Saturn's largest moon. view more (2009-08-13)
First RAVE data release offers clues to Milky Way evolution
An international team of astronomers released to the public the first data collected as part of the Radial Velocity Experiment, an ambitious spectroscopic survey aimed at measuring the speed, temperature, surface gravity and composition of up to a million stars passing near the sun. view more (2006-02-13)
From the surface of Mars to the skin on your body: UK science goes public
The 24 exhibits cover an extraordinary range of up-to-the-minute research. A model of the Beagle 2 robot lander - that will range over the Martian surface - is on show, as is a 3-D tour of an astronomical observatory in Hawaii. There is a novel look deep inside turbulent industrial processes; a chance to test your skills as a surgeon under the... view more... (1999-06-04)
Colossal Black Holes Common in the Early Universe
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form. view more (2008-10-17)
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)
Water shortages in Northeast Linked to Human Activity
Recent water shortages in Rockland County, N.Y., reveal an increasing mismatch between water demand and supply following rapid growth in the Northeast during period of abnormally high precipitation. view more (2006-05-18)
The Double Firing Burst
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth. view more (2008-09-11)
Magnetic Fields Play Larger Role in Star Formation than Previously Thought
he simple picture of star formation calls for giant clouds of gas and dust to collapse inward due to gravity, growing denser and hotter until igniting nuclear fusion. In reality, forces other than gravity also influence the birth of stars. New research shows that cosmic magnetic fields play a more important role in star formation than previously... view more...

Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. view more (2009-01-07)
Heavy Metal Stars: La Silla Telescope Detects Lots of Lead in Three Distant Binaries
Very high abundances of the heavy element Lead have been discovered in three distant stars in the Milky Way Galaxy. This finding strongly supports the long-held view that roughly half of the stable elements heavier than Iron are produced in common stars during a phase towards the end of their life when they burn their Helium - the other half... view more...

Starburst galaxy sheds light on longstanding cosmic mystery
An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. view more (2009-11-03)
Dark energy may be vacuum
Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. As part of the international collaboration ESSENCE they have observed distant supernovae (exploding stars), some of which emitted the light we now see more than half the age... view more...

Superstrings could add gravitational cacophony to universe's chorus
Albert Einstein theorized long ago that moving matter would warp the fabric of four-dimensional space-time, sending out ripples of gravity called gravitational waves. No one has observed such a phenomenon so far, but University of Washington researchers believe it is possible to detect such waves coming from strange wispy structures called cosmic... view more...
