DESI has made the largest 3D map of our universe to date and uses it to study dark energy. In this visualization, Earth is at the center, and every dot is a galaxy.

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 on 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.
