Gamma Ray Burst (GRB) are the most powerful burst in the entire universe after big bang. GRBs outshine every gamma source in the sky even the sun. They brightness is more than hundred times the brightness of the normal supernovae. Since the gamma rays have the highest energy in all the electromagnetic radiation, they are the most lethal for any life form. The Gamma Ray Bursts are able to devastate the life on Earth if happens to occurs in the neighbourhood of the solar system.

You will be surprised to know that these elements were not formed at the time of Big Bang Explosion. After the Big Bang only lighter elements like Hydrogen and Helium were formed. Then how the rest of the element originated? How did the materials for formation of planets and asteroids get formed?
