Gamma-ray bursts are the brightest and most powerful type of electromagnetic radiation that can be emitted in the universe in the outcome of a violent stellar explosion, whose afterglow remains extremely bright up to several hours after the occurrence of the event that generated it. A new study found that afterglows ... |

NASA's gamma-ray telescope developed in order to explore the high-energy universe, such as astrophysical and cosmological phenomena occurring inside active galactic nuclei, pulsars, dark matter and so on, has been fitted recently with the Ku-band communication system. The Ku-band system will have the role of ens... |

Three weeks ago, the Swift satellite detected the brightest gamma-ray burst in the visible universe in a galaxy located more than 7 billion light years away from Earth. It is though that the supernova explosion could have been the result of the collapse of a massive star into a black hole, and that, during the explos... |

GRB's, or gamma-ray bursts, are the most powerful radiation emissions released during cosmic collisions between massive objects such as neutron stars or possibly black holes. Most of the gamma-ray bursts received from the interstellar medium usually present long period bursts, which are thought to be produced b... |
