Abstract:
Gamma Ray Burst (GRBs) are the brightest explosions in the Universe. They are detected by orbiting space telescopes at the rate of about one a day. The number that could be detected from Earth should be much higher than the current rate, but the efficiency of the instruments is the obstacle. In spite of the fact, that GRBs are regularly observed they are still physics mysteries. The mechanism by which they convert energy into radiation remains a dark puzzle. Neither the light curves nor the early-time spectra of GRBs can be explained with the currently known physical processes. However, strong GRB from within our galaxy can induce serious damage on the heliosphere and can destroy earth's magnetosphere.
