SDSS - Sloan Digital Sky Survey

http://www.sdss3.org/

Program Description: The Sloan Digital Sky Survey is one of the most ambitious and influential surveys in the history of astronomy. Over eight years of operations (2000-2008) it obtained deep, multi-color images covering more than a quarter of the sky and created 3-dimensional maps containing more than 930,000 galaxies and more than 120,000 quasars. SDSS-III is working to map the Milky Way, search for extrasolar planets, and solve the mystery of dark energy. The project instrument is the Sloan Foundation 2.5-meter Telescope at Apache Point Observatory in New Mexico. Projects that have leveraged the Sloan Survey database include Galaxy Zoo, http://www.galaxyzoo.org/#/ a program that recruits volunteer citizen scientists to classify and identify objects within the stored images. The SDDS-III Project has been completed. Sloan Digital Sky Survey IV will operate from 2014-2020. SDDS IV experimental programs will include: APOGEE-2: A stellar survey of the Milky Way; eBOSS: A cosmological survey of quasars and galaxies encompassing the TDSS: a spectroscopic survey of variable sources.and SPIDERS: a survey of X-ray emitting sources from eROSITA.subprograms; and MaNGA: A survey to obtain resolved spectroscopy for 10,000 nearby galaxies.

Year Started: 2008.

Organization Description: The collaboration involves scientists in the U.S, EU, Japan, UK, and China. SDSS-III consists of four surveys executed on the same 2.5m telescope: the Apache Point Observatory Galactic Evolution Experiment (APOGEE) the Baryon Oscillation Spectroscopic Survey (BOSS), the Multi-Object APO Radial Velocity Exoplanet Large-area Survey (MARVELS), and the Sloan Extension for Galactic Understanding and Exploration 2 (SEGUE-2). BOSS focuses on mapping the Universe on the largest scales, creating the largest volume three-dimensional map of galaxies ever created. SEGUE-2 and APOGEE focus on the structure and evolution of our own Milky Way galaxy. MARVELS searches very nearby stars for evidence of "exoplanets" surrounding them. The SDSS-III collaboration contains scientists from many international member institutions
