Gamma-ray bursts have long been the record holders for the most energetic explosions in the universe. Results reported at a workshop last November and discussed by Piran in his Perspective show, however, that the previous energy estimates were too high because the emission was believed to be isotropic. With respect to energetics, gamma-ray bursts tie with supernovae. Gamma-ray bursts continue to hold the record as the brightest objects in the universe.
