Neil Gehrels Swift Observatory

The Neil Gehrels Swift Observatory, formerly known as the Swift Gamma-Ray Burst Mission, is a space telescope launched in November 2004. It is dedicated to studying gamma-ray bursts (GRBs)—the most energetic events in the universe. Equipped with a multi-wavelength array of instruments including a Burst Alert Telescope (BAT), an X-Ray Telescope (XRT), and an Ultraviolet/Optical Telescope (UVOT), Swift can rapidly detect GRBs and observe their afterglows in the gamma-ray, X-ray, ultraviolet, and optical wavebands. This observatory was named in honor of Neil Gehrels, its late project leader, recognizing his contributions to astrophysics. Swift’s quick-response capabilities and broad range of observational tools have made it a critical asset for both swift GRB assessment and multi-wavelength astronomical observations.
