DESI Fan and 3D Galaxy Fly-Through

DESI has made the largest 3D map of our Universe to date and uses it to study dark energy. Earth is at the center in this animation, and every dot is a galaxy. DESI is mounted on the U.S. National Science Foundation Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory (KPNO), a Program of NSF NOIRLab.
