Largest-ever 3D map of the universe shows 47 million galaxies, from the Milky Way to 'cosmic noon' - Live Science
Overview
The Dark Energy Spectroscopic Instrument (DESI) team has produced the largest-ever three-dimensional map of the universe, cataloguing 47 million galaxies and revealing large-scale structure with unprecedented scope. Local discoveries such as the Milky Way's "Loki" provide important ground-truth for interpreting DESI's statistical maps by showing how mergers and accretion shape individual galaxies. Together, broad surveys and nearby examples give researchers both the statistical backbone and the detailed cases needed to study galaxy growth, dark matter distribution, and environmental effects.
