Gamma ray burst (GRB),illustration. GRBs are focused beams of extremely high energy coming from distant galaxies. It is thought that they occur when a star is torn apart by powerful jets that form as it undergoes gravitational collapse. This massive short-lived burst of energy is hundreds of times brighter than an ordinary supernova or hypernova | |
