​​​​Gamma-Ray Bursts (GRBs) have kept astronomers fascinated since their accidental discovery in the early 1970s by military satellites. These bursts in mega electron-volt gamma rays briefly outshine the persistent gamma-ray emission from the entire universe. Now we know that one variety of these bursts, called long-duration GRBs, are death throws of extremely massive stars while another variety, called short-duration GRBs, are final episodes after mergers of two neutron stars in a binary system, emitting gravitational waves along with gamma rays. Located at cosmological distances, these are the most powerful electromagnetic explosions in the universe and can serve as laboratories for fundamental physics. In this talk I will present an overview of GRBs and recent discoveries related to them. ​​
