Astronomers using images from Kitt Peak National Observatory and Cerro Tololo Inter-American Observatory have created the largest ever map of the sky, comprising over a billion galaxies. The ninth and final data release from the ambitious DESI Legacy Imaging Surveys sets the stage for a ground-breaking 5-year survey with the Dark Energy Spectroscopic Instrument (DESI), which aims to provide new insights into the nature of dark energy. The map was released today at the January 2021 meeting of the American Astronomical Society. ....

The Beijing-Arizona Sky Survey (BASS) team of National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and their collaborators of the Dark Energy Spectroscopic Instrument (DESI) project released a giant 2D map of the universe, which paves the way for the upcoming new-generation dark energy spectroscopic survey.
Modern astronomical observations reveal that the universe is expanding and appears to be accelerating. The power driving the expansion of the universe is called dark energy by astronomers. The dark energy is still a mystery and accounts for about 68% of the substance of the universe. ....
