News Picks : Brightest gamma-ray burst ever detected
22 November 2013
BBC: The brightest and longest gamma-ray burst seen so far was detected 27 April by NASA’s Swift mission and the Fermi Gamma-Ray Space Telescope. The findings concerning GRB 130427A were published yesterday in Science. It is believed that this burst originated from the collapse of a massive star located about 3.6 billion light-years away—relatively close, by cosmic standards. As such stars run out of fuel, they collapse under their own weight and eject a burst of high-energy radiation. Because of its luminosity and proximity, GRB 130427A is providing researchers with valuable data to help them better understand such extremely energetic explosions.
