Arizona: The Largest Two-Dimensional Map of the Universe Counts More than a Billion Galaxies in a Newly Expanded Map

Its goal is to help astronomers further improve their understanding of the map of the universe, which may in turn help solve mysteries related to the mysterious properties of dark matter and dark energy.

The tenth data released by the Dark Energy Spectroscopic Instrument (DESI) is crucial.
Astronomers want to map the history of the universe for the last 12 billion years of existence.

The DESI survey is one of three surveys that imaged 14,000 square degrees of the Northern Hemisphere sky using telescopes at Kit Peak National Observatory in Arizona and the Cerro Tolulo Inter-American Observatory in Chile. Is.

A major goal of this mapping is to identify an estimated four million galaxies for the five-year DCI spectroscopic survey to help improve our understanding of the mysterious dark energy.
