In 29 new scientific papers, the Dark Energy Survey examines the largest-ever maps of galaxy distribution and shapes, extending more than 7 billion light-years across the Universe. The extraordinarily precise analysis, which includes data from the survey s first three years, contributes to the most powerful test of the current best model of the Universe, the standard cosmological model. However, hints remain from earlier DES data and other experiments that matter in the Universe today is a few percent less clumpy than predicted.

A five-year quest to map the universe and unravel the mysteries of dark energy began officially on May 17, 2021, at Kitt Peak National Observatory near Tucson, Arizona. The Dark Energy Spectroscopic Instrument (DESI) will capture and study the light from more than 30 million galaxies and other distant objects, allowing scientists to construct a 3-D map of the universe with unprecedented detail.
DESI is an international science collaboration that includes physicists from the University of Utah and is managed by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) with primary funding from DOE’s Office of Science.
