Scientists Release Biggest 2D Map of the Universe

Scientists Release Biggest 2D Map of the Universe - The new DESI Legacy Imaging Surveys map serves as the foundation for the largest-ever 3D map of the Universe, used to investigate dark energy

The newest DESI Legacy Imaging Surveys map, 13 years in the making, covers three-quarters of the sky and catalogs nearly four billion objects. This treasure trove is available to all and contains stars, galaxies, supernovae, gravitational lenses, and much more. Two NSF NOIRLab facilities contributed data to the map: the U.S. National Science Foundation (NSF) Mayall telescope and the NSF Blanco telescope, equipped with the U.S. Department of Energy-fabricated DECam.
