The Sloan Digital Sky Survey-V (SDSS-V) is the first facility providing multi-epoch optical & IR spectroscopy across the entire sky, as well as offering contiguous integral-field spectroscopic coverage of the Milky Way and Local Volume galaxies.

The Sloan Digital Sky Survey, or SDSS, is an international collaboration of scientists gathering data from two telescopes in North and South America to build the most detailed Three-Dimensional Imagery of the Universe ever made. The SDSS has produced deep multi-color images of one third of the sky, and created spectra of more than three million ...

The Sloan Digital Sky Survey (SDSS) is one of the most ambitious and influential surveys in the history of astronomy. Over eight years of operations (SDSS-I, 2000-2005; SDSS-II, 2005-2008), 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 ...

The SDSS addresses fascinating, fundamental questions about the universe. With the survey, astronomers will be able to see the large-scale patterns of galaxies: sheets and voids through the whole universe. Scientists have many ideas about how the universe evolved, and different patterns of large-scale structure point to different theories.

Some of the major discoveries that the SDSS has enabled are summarised on the SDSS-IV science results page, while some of the major science questions we will address in SDSS-V are given below. SDSS-V has also produced a number of publications, and will add many more as the survey progresses. To see the fully updated list, go to our Publications ...

DR18 is the first data release for the fifth phase of the Sloan Digital Sky Survey (SDSS-V). Its content is described in detail on the DR18 data release paper Almeida et al. (2023). DR18 includes the following: Targeting catalogs prepared for the Black Hole Mapper and Milky Way Mapper science programs, as well as for

Welcome to the DR14 site!!! This website presents data from the Sloan Digital Sky Survey, a project to make a map of a large part of the universe. We would like to show you the beauty of the universe, and share with you our excitement as we build the largest map in …

Scientists from the Sloan Digital Sky Survey (SDSS) have released a comprehensive analysis of the largest three-dimensional map of the universe ever created. The new results come from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), an SDSS collaboration of more than 100 astrophysicists worldwide.

sdss将绘制出人类历史上最大的天体图。它将为我们绘制出一个是目前为止所探索到的宇宙容积一百倍的三维的宇宙图画。sdss还将记录100，000个类星体（目前所知的最远的天体）的距离，并对我们能观测到的宇宙边缘物质分布方面给出前所未有的启发。
