3 unusual facts about Sloan Digital Sky Survey


Charge-coupled device

The Sloan Digital Sky Survey is the most famous example of this, using the technique to produce the largest uniform survey of the sky yet accomplished.

Joint Institute for Nuclear Astrophysics

JINA is heavily involved in observations with the Apache Point Observatory within the framework of extensions to the Sloan Digital Sky Survey, LAMOST in China, SkyMapper in Australia, and the Hubble Space Telescope.

Michael Blanton

A former postdoctoral fellow at Fermilab, he was part of a team that constructed the largest-ever three-dimensional map, produced by the Sloan Digital Sky Survey, of massive galaxies and distant black holes using data from the Sloan Foundation Telescope at Apache Point Observatory in New Mexico.


Arne Henden

He has also worked on the Sloan Digital Sky Survey and consulted for the Radio Astronomy Institute in developing a robotic observatory near the Grand Canyon.

Milky Way

On January 9, 2006, Mario Jurić and others of Princeton University announced that the Sloan Digital Sky Survey of the northern sky found a huge and diffuse structure (spread out across an area around 5,000 times the size of a full moon) within the Milky Way that does not seem to fit within current models.

Observational cosmology

Redshift surveys have been a common means by which this has been accomplished with some of the most famous including the 2dF Galaxy Redshift Survey, the Sloan Digital Sky Survey, and the upcoming Large Synoptic Survey Telescope.

Ralph E. Gomory

Among scientific achievements, the foundation supported the widely recognized Sloan Digital Sky Survey, which has made major contributions to the problem of dark energy, and initiated a major worldwide effort to survey life in the oceans known as the Census of Marine Life.

SDSS J130114+2743

SDSS J130114+2743 is a galaxy in the constellation Coma Berenices, host galaxy of SN 2005ap.
