Mission
Because gamma rays and X-rays cannot penetrate Earth's atmosphere, direct observations must be made from space.
Objects such as the mysterious gamma-ray bursters and supernovae are the targets of interest of this satellite.
occurred on March 5, 1979, and was detected by several satellites. Since then, N 49 has had several subsequent gamma-ray emissions, and is now recognized as a "soft gamma-ray repeater," releasing lower-energy gamma-rays than most gamma-ray bursters.
