DESI Year-3 Fan Plot

Two ‘fans’ corresponding to the two main areas DESI has observed, above and below the plane of our Milky Way (see this map). 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. DESI has made the largest 3D map of our Universe to date and uses it to study dark energy. Earth is at the center of the two fans, where bluer points indicate more distant objects. This is a still from an animated rotation of the DESI Year-3 data map.
