Sloan Digital Sky Survey (SDSS)

TypeData set
SubjectAstronomy and astrophysics
AbstractThe Sloan Digital Sky Survey (SDSS) began in the year 2000 and provides data to support detailed investigations of the distribution of luminous and non-luminous matter in the universe: a photometrically and astrometrically calibrated digital imaging survey and a spectroscopic survey of the approximately 106 brightest galaxies and 105 brightest quasars found in the photometric object catalog produced by the imaging survey. This multi-filter imaging and spectroscopic redshift survey uses a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico. In 2006 the survey (SDSS-II) was extended to explore the structure and stellar makeup of the Milky Way. In mid-2008 SDSS was extended again (SDSS-III) to include surveys of dark matter (BOSS), the outer Milky Way (SEGUE-2), the inner galaxy (APOGEE) and extra-solar planets (MARVELS). In July 2008 SDSS-III released its first public data as Data Release 8, which contains all images from the SDSS telescope, and builds continuity with previous SDSS releases. It includes measurements for nearly 500 million stars and galaxies, and the spectra for almost two million. All the images, measurements, and spectra are available free online.
