DESI Begins: The Dark Energy Spectroscopic Instrument
The Dark Energy Spectroscopic Instrument (DESI) will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3D map spanning the nearby universe to 11 billion light years. The DESI Survey will be conducted on the Mayall 4-meter telescope at Kitt Peak National Observatory, which is operated by the National Science Foundation's National Optical-Infrared Astronomy Research Laboratory.
