Largest-ever 3D map of universe with 47 million galaxies aims to probe dark energy
An international research team has completed the largest high-resolution 3D map of the universe ever made, built from five years of observations tracking tens of millions of galaxies. The map, created through the Dark Energy Spectroscopic Instrument (DESI) project, contains data on more than 47 million galaxies and quasars, exceeding its initial target. Researchers also observed more than 20 million nearby stars to study the Milky Way, and plan further observations to refine results on dark energy.
