<p>The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic <a href="/facts/Redshift_survey/mXtC61WX">redshift survey</a> using a dedicated 2.5-m wide-angle <a href="/facts/Optical_telescope/dVfBR10I">optical telescope</a> at <a href="/facts/Apache_Point_Observatory/UPJCGavT">Apache Point Observatory</a> in New Mexico, United States. The project began in 2000 and was named after the <a href="/facts/Alfred_P._Sloan_Foundation/bIGkfYAS">Alfred P. Sloan Foundation</a>, which contributed significant funding.
</p><p>A consortium of the <a href="/facts/University_of_Washington/36PG6qkG">University of Washington</a> and <a href="/facts/Princeton_University/n3EPGHBM">Princeton University</a> was established to conduct a redshift survey. The Astrophysical Research Consortium (ARC) was established in 1984 with the additional participation of <a href="/facts/New_Mexico_State_University/CRh0lEgp">New Mexico State University</a> and <a href="/facts/Washington_State_University/m0GFu1vA">Washington State University</a> to manage activities at Apache Point. In 1991, the Sloan Foundation granted the ARC funding for survey efforts and the construction of equipment to carry out the work.
