Sloan Digital Sky Survey (SDSS)

The Sloan Digital Sky Survey (SDSS) is a major astronomical project that maps the universe by capturing detailed images and spectra of millions of stars, galaxies, and other celestial objects. Using powerful telescopes and advanced cameras, SDSS creates comprehensive 3D maps of the cosmos, helping scientists study the universe's structure, origins, and evolution. The data is publicly accessible, fostering worldwide research and discoveries about the universe's size, composition, and history.
