The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States.
IC 1101 imaged by the Sloan Digital Sky Survey. The galaxy is classified as a supergiant elliptical (E) to lenticular (S0) [23] and is the brightest galaxy in A2029 (hence its other designation A2029-BCG; BCG meaning brightest cluster galaxy).
The Sloan Great Wall (SGW) is a cosmic structure formed by a giant wall of galaxies (a galaxy filament). Its discovery was announced from Princeton University on October 20, 2003, by J. Richard Gott III, Mario Jurić, and their colleagues, based on data from the Sloan Digital Sky Survey. [1]
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. ... SDSS stands for Sloan Digital Sky Survey, ...
Galaxy Zoo is a project aiming at a more comprehensive list: launched in July 2007, it has classified over one million galaxy images from The Sloan Digital Sky Survey, The Hubble Space Telescope and the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey. [2]
NGC 1052-DF2 is an ultra diffuse galaxy (UDG) identified in a wide-field imaging survey of the NGC 1052 group by the Dragonfly Telephoto Array. [2] It has been proposed that the galaxy contains little or no dark matter, the first such discovery.
