Latest GRB 080916C Stories
On Saturday, April 27, the Fermi Gamma-ray Telescope detected a sudden, powerful flux of high-energy gamma-rays, indicating a historic burst event in a distant galaxy. The instrument then notified other telescopes located in space and on the ground that a Gamma-ray Burst (GRB) had been detected.
Detectable for only a few seconds but possessing enormous energy, gamma-ray bursts are difficult to capture because their energy does not penetrate the Earth's atmosphere.
NASA reported recently that astronomers can say with certainty there is no fear of a supernova being close enough to hurt Earth, especially by 2012.
ESAâ€™s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein.
Gamma-ray bursts are among the most energetic events in the Universe, but some appear curiously faint in visible light.
A gamma-ray burst is an immensely powerful blast of high-energy light thought to be generated by a collapsing star in a distant galaxy, but what this collapse leaves behind has been a matter of debate.
Astronomers studying two exploding stars, or supernovae, have found evidence the blasts received an extra boost from newborn black holes.
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity.
NASA will hold a news teleconference at 2 pm EDT on Wednesday, Oct 28, to discuss the first-year science results from the Fermi Gamma-ray Space Telescope.
