The American Astronomical Society (AAS) has announced its selection of the DESI collaboration as the recipient of the 2026 Lancelot M. Berkeley–New York Community Trust Prize. Established in 2011, the prize is awarded annually for highly meritorious work advancing astronomy in the previous year. Previous recipients have included both individuals and teams for their work […]

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.
Latest News from DESI
New results from the first 3 years of DESI data strengthen hints that dark energy is evolving, with consequences for our understanding of nature and the fate of the Universe. Read more in the March 2025 BerkeleyLab Press Release. Videos discussing the results are available at the DESI YouTube channel. Further details are available in our guide to the publications reporting these results. The papers themselves are available here.
A new DESI data release is also now available for all to explore. The largest dataset of its kind ever shared, it contains information on 18.7 million galaxies, quasars, and stars. Read more in a companion BerkeleyLab Press Release.

Black Holes that Convert Matter into Dark Energy Allow for Positive Neutrino Masses
21 August 2025 Joan Najita (NOIRLab) DESI recently reported compelling evidence that dark energy is dynamic and evolves with time. What drives this evolution? In a recent paper, a group of DESI scientists propose that the evolution is driven by the creation of non-singular black holes, which converts ordinary (baryonic) matter into dark energy. The […]

DESI High, the School of the Dark Universe, is Back!
by Alma González (University of Guanajuato, Mexico) and Martine Lokken (Autonomous University of Barcelona, Spain) 24 April 2025 DESI’s educational program for high school students, DESI High, is now back in session! Designed so students can work with DESI data directly from the telescope, the program also introduces fundamental concepts in cosmology and helps develop […]
