For over a quarter of a century, gamma-ray bursts were the outstanding mystery in astronomy. No one knew where they were or how they worked. The Biggest Bangs tells how the mystery was unraveled, from the discovery of gamma-ray bursts by a Cold War satellite system monitoring the Nuclear TestBan Treaty to the localization of bursts in distant galaxies and the observation of surprisingly bright flashes of light from the bursts themselves. The Biggest Bangs is for laymen with an interest in science, physicists and astronomers interested in subjects in those fields not their specialty,students in non-technical astonomy courses, and as supplemental reading for courses in the history of science.
