Five-Year Sky Survey Maps 47 Million Galaxies to Probe Dark Energy
TL;DR
The Dark Energy Spectroscopic Instrument (DESI) completed the most detailed cosmic survey to date, mapping more than 47 million galaxies and quasars across about 14,000 square degrees to create a 3D map of the universe. The dataset aims to test whether dark energy evolves over time and will be analyzed further before broader public access, with future observations planned to extend the coverage and duration into the 2030s.
