The Dark Energy Spectrometer creates the largest and most detailed 3D map of the universe to date

IT House January 17 news, according to science and technology daily report, the United States dark energy spectrometer (DESI) project broke all previous records for 3D galaxy surveys, after completing the first seven months of surveys, created the largest and most detailed map of the universe ever.

DESI's Five-Year Mission is currently only about 10 percent complete, but this extremely detailed 3D map will help humans better understand dark energy, giving scientists insight into the past and future of the universe.

DESI's 3D "CT scan" of the universe, with the Earth in the lower left corner, looking towards the constellation Virgo, has the past 5 billion light-years, with each colored dot representing a galaxy made up of 100 billion to 1 trillion stars. Gravity aggregates galaxies into structures called "cosmic webs," which have dense clusters of stars, filaments, and voids.

IT House understands that DESI is an international scientific cooperation project managed by the U.S. Department of Energy's Lawrence Berkeley National Laboratory (hereinafter referred to as Berkeley Lab), and the main funding for its construction and operation comes from the U.S. Department of Energy's Office of Science. DeSI began construction in 2015 and was installed on the Nicholas U. Mayall 4-meter telescope at kitt peak national astronomical observatory near Tucson, Arizona.

The DESI project has cataloged more than 7.5 million galaxies and is increasing at a rate of more than 1 million per month. In November 2021 alone, DESI cataloged redshifts from 2.5 million galaxies. By the end of operation 2026, DESI's catalog is expected to contain more than 35 million galaxies, enabling a wide variety of cosmological and astrophysical studies.
