Early Dark Energy Spectroscopic Instrument (DESI) release holds nearly two million objects, including distant galaxies, quasars and stars in our own Milky Way.

Dark Energy Spectroscopic Instrument (DESI), the most robust multi-object survey spectrograph, capable of mapping more than 40 million galaxies, quasars, and stars, recorded an 80-terabyte data set this Tuesday.

The data was collected after 2,480 exposures taken over six months during the experiment’s “survey validation” phase in 2020 and 2021, said Lawrence Berkeley National Lab.
