The Dark Energy Spectroscopic Instrument (DESI) has completed its original five-year survey and delivered the most detailed map of the universe ever made. Operating from the Kitt Peak National Observatory in Arizona, DESI has charted more than 47 million galaxies and quasars in three dimensions.
The result is a high-resolution cosmic map that stretches across billions of years, offering scientists an unprecedented dataset to probe how the universe has evolved.
