Scientists have achieved a significant breakthrough in their effort to understand dark energy by completing observations for the full target area of the Dark Energy Spectroscopic Instrument (DESI)'s 3D map of the universe.

The project wrapped up ahead of schedule and delivered far more data than originally anticipated. This map is now the most detailed high-resolution 3D representation of the universe ever created. Researchers will use it to investigate dark energy, the mysterious force believed to make up about 70% of the cosmos.

47 Million Galaxies Mapped in Unprecedented Detail

Over five years of observations, DESI recorded more than 47 million galaxies and quasars along with 20 million stars.…
