Neil Gehrels Swift Observatory

NASA's Neil Gehrels Swift Observatory is a rapidly repointing, multiwavelength telescope built to detect gamma-ray bursts and study their afterglows. Its Burst Alert Telescope, X-Ray Telescope, and Ultraviolet/Optical Telescope work together to locate transient events and begin follow-up observations within minutes.

Description
NASA's Neil Gehrels Swift Observatory is a rapidly repointing, multiwavelength telescope built to detect gamma-ray bursts and study their afterglows. Its Burst Alert Telescope, X-Ray Telescope, and Ultraviolet/Optical Telescope work together to locate transient events and begin follow-up observations within minutes.
Launch Site
Outcome
Swift remains an active time-domain observatory after more than two decades. It has localized and characterized gamma-ray bursts, supported rapid international follow-up, and expanded its observing program to supernovae, tidal-disruption events, novae, active galaxies, and other transient sources.
