A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts-both extremely luminous, distant objects-has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars. view more (2006-08-01)
Astrophysicists Solve Mystery in Milky Way Galaxy
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. view more (2009-07-09)
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)
On October 10th at the Canaries the Magic telescope will be inaugurated: the biggest in the world for the study of gamma radiation
On October 10th the Magic Telescope (Major Atmospheric Gamma Imaging Cherenkov telescope) will be inaugurated. The telescope is located La Palma island, 2200 meters above the sea level at the Observatory Roque de los Muchachos, of the Itituto Astrofisico de Canarias. With his 17-meter-diameter-mirror and 240 square meters surface, it's the largest... view more... (2003-10-06)
NASA's Fermi Finds Gamma-ray Galaxy Surprises
Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. view more (2009-07-15)
GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays. view more (2008-08-27)
Invading black holes explain cosmic flashes
Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today. view more (2009-09-21)
Delta II Rocket Coming Together for NASA's GLAST Satellite Launch
The Delta II 7920-H, or "Heavy," rocket that will launch NASA's Gamma-ray Large Area Telescope (GLAST) satellite is in the process of being assembled on Launch Pad 17-B at Cape Canaveral Air Force Station, Fla. view more (2008-04-15)
Molecules of positronium observed in the laboratory for the first time
Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their antiparticles, called positrons. view more (2007-09-13)
Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these extraordinary explosions from the X-rays given out... view more... (2003-09-17)
NASA's Swift Catches Farthest Ever Gamma-Ray Burst
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away. view more (2008-09-23)
Where are the supermassive black holes hiding?
European and American scientists, on a quest to find super-massive black holes hiding in nearby galaxies, have found surprisingly few. Either the black holes are better hidden than scientists realised or they are lurking only in the more distant universe. view more (2006-07-27)
Stem cells could halt osteoporosis, promote bone growth
While interferon gamma sounds like an outer space weapon, it's actually a hormone produced by our own bodies, and it holds great promise to repair bones affected by osteoporosis. view more (2009-03-05)
European Satellites Probe a New Magnetar
On Aug. 22, 2008, NASA's Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. view more (2009-06-17)
Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB). view more (2009-10-29)
Integral - tracking extreme radiation across the Universe
INFO 8-2002. Integral is the International Gamma Ray Astrophysics Laboratory of the European Space Agency. It is a cooperative mission with Russia and is scheduled for launch on 17 October 2002 from the Baikonur Cosmodrome, Kazakhstan, on a Russian Proton rocket, the Russian contribution to the programme. It is the world`s most advanced... view more... (2002-10-02)
Astronomers use gamma-ray burst to probe star formation in the early universe
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. view more (2009-01-07)
UC Santa Cruz physicists eagerly await launch of NASA space telescope they helped build
When NASA launches its newest space observatory, physicists at the University of California, Santa Cruz, will be watching as the product of nearly 16 years of hard work blasts into orbit. view more (2008-05-30)
Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated - a finding that may help fine-tune therapies for depression. view more (2009-10-19)
NSF / NASA 'Firefly' CubeSat Mission to Study Link Between Lightning and Terrestrial Gamma Ray Flashes
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected only from space. view more (2008-11-18)
