Sloan Digital Sky Survey

(SDSS)
(imaging survey of 500,000,000 objects in 35% of sky)

The Sloan Digital Sky Survey (SDSS) is a series of Surveys (or "survey phases") carried out with the Sloan 2.5m Telescope at Apache Point Observatory (APO), New Mexico, which was built for the purpose. It is named for Alfred P. Sloan Foundation.

Surveying began in 2000, covering 35% of sky, with Photometry of 500 million objects and spectra of 1 million objects. The median Redshift of the galaxies is redshift z = .1, reaching as far as z = .7, with Quasars to redshift z = 6 and beyond.

The original survey (SDSS-I) was Visible Light images using a Photometric System of five Bands:
