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.

This video describes the monumental effort that went into constructing a 2D map of the universe to prepare for the Dark Energy Spectroscopic Instrument, which will produce the largest-ever 3D map of the universe. The final data release for the preparation of this 2D map, known as Data Release 9 or DR9, was distributed Jan. 13. (Credit: Marilyn Sargent/Lawrence Berkeley National Laboratory)
