The map reveals about three-quarters of the night sky in high resolution, spanning both visible and near-infrared light wavelengths and charting the areas of the universe not blocked by dust or gas. The map is so big, in fact, that it’s impossible to reproduce as a single image here; instead, astronomers invite you to explore their vision of the universe using the free Legacy Survey Sky Browser webpage.
"Astronomers and citizen scientists can combine the map with their own observations to better understand our universe," NSF officials from NOIRLab said in a statement Aug. 10.

DESI's first five-year survey wrapped up in April, and the early results suggest dark energy may be getting weaker with time. As physicists grapple with the implications, including how the universe may end, more data from DESI is coming shortly, with improved results from the first five years expected next year. DESI's work will continue into 2028, so even more is to come.
The three telescopes behind the map are The Dark Energy Camera, mounted on the NSF’s Victor M. Blanco 4-meter Telescope in Chile, the NSF Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory in Arizona, and the UA Bok 2.3-meter Telescope, also at Kitt Peak. The observations were supplemented by years of data from NASA’s Wide-field Infrared Survey Explorer (WISE) satellite mission.
