Thanks to a clever piece of design and a sophisticated piece of analysis by European astronomers, Integral - ESA's orbiting gamma ray observatory - can now make images of the most powerful gamma-ray bursts even if the spacecraft itself is pointing somewhere completely different. Scientists know that once every day or two, a powerful gamma ray burst (GRB) will take place somewhere in the Universe. Most will last between 0.1 and 100 seconds, so if your telescope is not pointing in exactly the...

LONDON (Reuters) - Three international teams of astronomers said on Wednesday they have detected the most distant gamma ray burst ever observed in the early Universe. The cosmic explosion, a gamma ray burst (GRB) called GRB 050904, was detected by astronomers in the United States, Japan and Italy last September using NASA's Swift satellite. A gamma ray burst is the most distant and powerful type of explosion known to astronomers. It can last from a few milliseconds to several...

An international team of astronomers led by Danish astronomer Jens Hjorth [1] has for the first time observed the visible light from a short gamma-ray burst (GRB). Using the 1.5m Danish telescope at La Silla (Chile), they showed that these short, intense bursts of gamma-ray emission most likely originate from the violent collision of two merging neutron stars. The same team has also used ESO's Very Large Telescope to constrain the birthplace of the first ever short burst whose position could...

First simultaneous observation of a gamma-ray burst in the X-ray and in the very high energy gamma ray band For the first time a gamma-ray burst (GRB) has been observed simultaneously in the X-ray and in the very high energy gamma ray band. The MAGIC telescope at La Palma, Canary Islands, observed the enigmatic source GRB050713A, a long duration gamma-ray burst, only 40 seconds after the explosion, at photon energies above 175 GeV. The puzzling nature of gamma-ray bursts is still not fully...

Cambridge, MA -- Reporting in the May 12th issue of Nature, astronomers announced that they have penetrated the heart of the universe's most powerful explosion - a gamma-ray burst (GRB). Using the PAIRITEL (Peters Automated Infrared Imaging Telescope) robotic telescope on Mt. Hopkins, Arizona, they detected a flash of infrared light accompanying the burst of high-energy radiation that signaled the death of a star roughly fifteen times more massive than the Sun. "This is the first time...
