Artist’s depiction of DESI first year data slice

In this artistic rendering, a slice of the 3D map of galaxies collected in the first year of the Dark Energy Spectroscopic Instrument (DESI) Survey appears in a rainbow of color above the NSF Nicholas U. Mayall 4-meter Telescope, on which DESI is mounted. Earth is at the tip of the map, with the furthest galaxies plotted at distances of 11 billion light-years. Each point represents one galaxy. This version of the map includes 600,000 galaxies — less than 0.1% of the survey's full volume.
