The instrument, whose technological development has been keyly supported by the Institute of Astrophysics of Andalusia (IAA-CSIC), has completed its original five-year mission, mapping more than 47 million galaxies and quasars and creating the largest high-resolution, three-dimensional map of the universe to date. Thanks to its excellent performance and indications that dark energy may evolve over time, DESI will continue its observations until 2028 and further expand the map.
