  • DESI is a state-of-the-art instrument on the 4-meter Mayall telescope at Kitt Peak Observatory in Arizona. DESI can capture light from up to 5,000 celestial objects simultaneously. It is visible a long black cylinder supported by the metal framework of the telescope, points at the domed ceiling.Credit: Marilyn Sargent/Berkeley Lab
