Gamma-ray burst (GRB) research has made a quantum leap in the last three or four years, with the discovery of slowly fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence for many of them being associated with star forming regions and possibly supernovae. Significant progress has been made in understanding how the GRB and afterglow radiation arise in terms of the relativistic fireball shock model. New avenues of inquiry have opened up dealing with the nature of the central engine, the identity of their progenitors, the effects of the environment, and their possible gravitational wave, cosmic ray and neutrino luminosity. The puzzles and possibilities associated with these recent developments ensure that GRB remain among the most mysterious objects in astrophysics.
