Exempel på hur man kan använda SDSS i en mening
- During its first phase of operations, 2000–2005, the SDSS imaged more than 8,000 square degrees of the sky in five optical bandpasses, and it obtained spectra of galaxies and quasars selected from 5,700 square degrees of that imaging.
- GALEX Arecibo SDSS Survey GASS designed to measure the neutral hydrogen content of a representative sample of ~1000 massive, galaxies.
- These advances include observations of the microwave background from the COBE, WMAP and Planck satellites, large new galaxy redshift surveys including 2dfGRS and SDSS, and observations of distant supernovae and gravitational lensing.
- Data in the NVO Closeout Repository are available from a variety of observatories and wavelengths, including NSF's National Optical Astronomy Observatory (NOAO), National Radio Astronomy Observatory (NRAO), the Sloan Digital Sky Survey (SDSS), and the 2 Micron All Sky Survey (2MASS).
- In addition to astrometric studies (such as for Space Situational Awareness, SDSS and SST), research on this telescope includes the study of blue and K-Giant stars, celestial mechanics and dynamics of multiple star systems, characterizations of artificial satellites, and the astrometry and transit photometry of exoplanets.
- Analyzing data from large observational surveys, such as the SDSS or 2 Micron All Sky Survey (2MASS), can be challenging due to the huge number of data produced.
- Barney has been characterized as a stony S-type asteroid in the SDSS taxonomy of the Moving Object Catalog (MOC) and by the survey conducted by Pan-STARRS.
- As a result of the interest in similar ionized clouds for the study of both the history and obscuration of Active Galactic Nucleus (AGN), participants in the Galaxy Zoo (GZ) project carried out a wide search for such clouds using data from the Sloan Digital Sky Survey (SDSS).
- The Council of the Local Board has seven members, and the President is Saša Jurešić (SDP, HNS, PGS, SDSS).
- In it they compare the oxygen and nitrogen abundances derived from global emission-line SDSS spectra of galaxies using (1) the electron temperature method and (2) two recent strong line calibrations: the O/N and N/S calibrations.
- The actual structure was identified by Newberg and associates (2002) plus Majewski and associates (2003) using data from the 2MASS and SDSS surveys.
- Over 30 individuals and groups contributed their efforts to acquiring and processing the images, including Gordan Ugarkovic (largest image donor: Cassini, Huygens, Messenger, LRO), Colin Legg (astrophotographer), Val Klavans (image donor and image processor), Bill Eberly (lead SDSS image processor), Jason Harwell (lead Hubble/ESO image processor), Judy Schmidt (Hubble/ESO image processor) and Ian Regan (lead image processor and donor: Titan/Saturn/Jupiter).
- by selection of sources with colours typical for T dwarfs from WISE All-Sky source catalogue and checking them for high proper motion using older surveys: 2MASS, DENIS, SDSS, SSS, DSS and UKIDSS.

- According to a study published in the 9 January 2020 issue of the journal Nature, CHIME astronomers, in cooperation with the radio telescopes at European VLBI Network (VLBI) and the optical telescope Gemini North on Mauna Kea, Hawaii, were able to pinpoint the source of FRB 180916 to a location within a Milky Way-like galaxy named SDSS J015800.
- Unlike other planetesimals around white dwarfs, the planetesimal SDSS J1228+1040 b needs high internal strength and a high density to not be tidally disrupted.
- The fact that SDSS 1557B is tidally locked creates vast temperature changes in the dayside and nightside of the brown dwarf.
