With Over 47 Million Galaxies And Quasars, The Largest 3D Map Of The Universe Is Now Complete

The five-year survey finished ahead of schedule and with more data, hinting at unexpected dark energy properties. The Dark Energy Spectroscopic Instrument (DESI) has achieved its goal. Every single area of the sky that the collaboration set out to map has been mapped, and slightly ahead of its five-year target. DESI was set to gather data on 34 million galaxies and quasars. The final tally of the survey was 47 million galaxies and quasars, the largest high-resolution 3D map of the Universe ever assembled. The ultimate goal is to understand dark energy. Dark energy is a crucial component that is...
