The story behind creating and naming our favorite coyote. Samuel Brieden, The University of Edinburgh May 12, 2023 Welcome our new DESI ambassador for Education and Public Outreach (EPO), BaoBan! You might have met him already, when he was presenting our powerful focal plane (see a virtual tour through it here) or wishing a happy […]
The Dark Energy Spectroscopic Instrument (DESI)The Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe. It 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 is being conducted on the Mayall 4-meter telescope at Kitt Peak National Observatory. DESI is supported by the Department of Energy Office of Science to perform this Stage IV dark energy measurement using baryon acoustic oscillations and other techniques that rely on spectroscopic measurements.
5000 Eyes: Mapping the Universe with DESI is out now!
DESI's very own planetarium show is available for free to all planetariums. See the trailer and find more information here.
Translations in French, Spanish, Mandarin, and German are now available.
"After Fire and Monsoons, DESI Resumes Cataloguing the Cosmos
Collaborators on the Dark Energy Spectroscopic Instrument breathe a sigh of relief as they successfully restart the state-of-the-art experiment."

5000 Eyes: Creating the DESI Planetarium Film
Claire Lamman, Harvard University April 7, 2023 DESI’s planetarium show, “5000 Eyes”, was recently released to the public. It will be shown in hundreds of planetariums around the world and translated into ten languages. The support and contributions of many DESI members grew this project far beyond the little film I initially imagined. Here is […]
