GRB 990510: Another Unusual Gamma Ray Burst
Gamma-ray bursts are some of the most powerful explosions in the universe, releasing immense energy in seconds. Instruments like BATSE on the Compton Gamma Ray Observatory and Beppo-SAX detect these flashes. After a burst, astronomers quickly turn optical telescopes to the location to study the fading afterglow. These events provide clues to the deaths of massive stars or the mergers of neutron stars.
