Swift Spacecraft Animation

NASA’s Neil Gehrels Swift Observatory, shown in this illustration, launched into Earth orbit in November 2004. The satellite investigates gamma-ray bursts, the most energetic explosions in the universe. Swift observes the sky in visible, ultraviolet, X-ray, and gamma-ray light. Its name reflects its ability to rapidly follow up on interesting objects in the sky. Swift also studies supernova explosions, star-shredding black holes in other galaxies, comets, stellar remnants called neutron stars, and other cosmic phenomena. In 2018, NASA renamed Swift in honor of the late Neil Gehrels, who helped develop the mission and served as its principal investigator for 13 years.

Swift, illustrated here, is a collaboration between NASA’s Goddard Space Flight Center in Greenbelt, Maryland, Penn State in University Park, the Los Alamos National Laboratory in New Mexico, and Northrop Grumman Innovation Systems in Dulles, Virginia. Other partners include the University of Leicester and Mullard Space Science Laboratory in the United Kingdom, Brera Observatory in Italy, and the Italian Space Agency.
