Gamma Ray Burst Discoveries by the Swift Mission

The NASA Swift mission, in orbit since November 2004, is an innovative new multiwavelength observatory designed to determine the origin of gamma-ray bursts and use them to probe the early Universe. Early results from the mission will be presented. The long-standing mystery of short GRBs is beginning to be solved in a most interesting direction. High redshift bursts have been detected to redshift z=6.3 leading to a better understanding of star formation rates a early times. GRBs have been found with giant X-ray flares occurring in their afterglow. The very nearby GRB 060218 has an accompanying supernova SN 2006aj that is being observed to date.
