The Compton Gamma Ray Observatory was somewhat the equivalent of the Hubble Telescope almost a decade ago, in terms of searching for gamma-ray bursts, the most immense blasts ever detected in the vastness of space, from 1991 to 2000. Sadly, in June 2000, following a major glitch of the device, NASA decided to retire ... |

The Fermi telescope from NASA has managed to depict from the myriads of celestial bodies the only one that emits its pulses in gamma-ray beams alone. It is about 10.000 years old and it sends its light towards Earth at a rate of 3 times per second or, more precisely, once every 316.86 milliseconds. The amount of ener... |

One of the most expected launches of the year was carried out yesterday at approximately 12:05 pm EDT from NASA's Launch Complex 17-B at the Cape Canaveral Air Force Station, with the help of a Delta II rocket. The newest high-energy gamma-ray space observatory GLAST was launched into space and inserted into Ear... |

NASA's GLAST satellite, or the Gamma-ray Large Area Space Telescope, set to study the universe at its highest energies was scheduled for launch on June 3rd, between 11:45 a.m. and 1:40 p.m. EDT from the Launch Complex 17 at NASA's Cape Canaveral Air Force Station. GLAST will be carried into space with the h... |

The vast majority of stars end their lives through supernova explosions while others, more massive, are thought unable to produce such explosions simply because they implode and collapse under their own weight only to produce a black hole. Since these particular types of stellar death don't generate brilliant em... |

Nuclear weapons generate high explosive energies by either fusing or splitting certain chemical elements. A new type of nuclear explosive developed by the US Department of Defense, on the other hand, uses nuclear reactions in order to determine gamma-ray emissions carrying energies about one thousand times larger tha... |

The Thomson-Radiate Extreme X-ray Source is an energetic light source emitting picosecond laser pulses and possibly one of the brightest laser light sources in the world at this moment. T-REX is a LLNL project developed in collaboration with the NIF & Photon Science Principle Directorate and the Physical Sciences Dir... |

It would certainly appear so, and considering that our galaxy is filled with at least 200 billion stars, it would be no surprise if one of these rays of death would decide to hit our planet some day. However, the subject of discussion here is a star dubbed WR104, located about 8,000 light years from Earth in the Sagi... |

We used to think that Quasi Stellar Objects or quasars are the most energetic structures in the Universe, but this doesn't seem to be the case with the Milky Way, and why would our galaxy be more special than the others? The quasar is a special type of black hole, which goes through a 'feeding' process... |

A new instrument went online at the ESO Telescope at the La Silla Observatory and was able to take images simultaneously in seven colors, to examine the most energetic phenomena in the universe, the gamma-ray bursts.From time to time, a huge explosion followed by a bright flash of light can be observed in space. It&... |

In a vacuum, light travels at a speed of nearly 300,000 km/s (186,282 mi/s) and it's generally believed that matter cannot exceed this speed. Recently, astronomers discovered matter traveling at more than 99.999% the speed of light.It's the fastest speed ever recorded in the case of matter in the universe,... |

From time to time, a huge explosion followed by a bright flash of light can be observed in space. It's a colossal gamma-ray burst (GRB), emitting for a few seconds as much radiation as a million galaxies.A new discovery made by NASA's Swift satellite showed that the extremely energetic flares that follow a... |
