Swift's Key Discoveries

Swift discoveries are answering key questions on gamma-ray bursts (GRBs). They have confirmed the promise of GRBs as unique probes of the high-redshift Universe and provided key information on the birth of black holes. Rapid, uniform observations on broad time scales make Swift the most capable GRB observatory ever. The XRT detects 88% of all GRB X-ray afterglows and 40% of all optical afterglows.

Swift is a multi-purpose observatory that has evolved into a major general observing facility. Swift has observed supernovae, cataclysmic variables, active galactic nuclei, galactic transients, active stars, comets, and many other phenomena. Target of opportunity observations from the astrophysics community account for 55% of Swift's observing time

Some of Swift's key discoveries (as of Feb 2010) are listed here.
