The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as stars in our own Milky Way. DESI has already observed more galaxies than the combination of any other previous study, and it is just starting. Several Spanish institutions participate in this project: IFAE, ICE-CSIC/IEEC, ICCUB, CIEMAT, IFT/UAM, IAA, and IAC
