DESI, the Dark Energy Spectroscopic Instrument, has released a massive dataset containing information on 18.7 million celestial objects, including stars, galaxies, and quasars. The project aims to map the universe to better understand dark energy, uncovering hints that challenge our standard model of cosmology. DESI’s Data Release 1 is a fraction of what is to come but already holds twice as many extragalactic objects as all previous 3D surveys combined. The dataset is free to access and available for worldwide investigation, demonstrating innovative technology and scientific collaboration in the study of astrophysics.
