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 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.

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 …

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。

Galaxies are found in clusters of hundreds or thousands, held together by their mutual gravity. One of the SDSS's major goals is to understand how galaxies form clusters and larger structures, up to the large-scale structure of the universe.

Each filter is designed to let in light around a specific wavelength. The filters work by blocking out light at all wavelengths except those around the wavelength they are designed to see. The table to the right shows the wavelengths at which SDSS's five filters work the best.

sdssでは全天の4分の1を体系的に観測し, その詳細な画像を作って そこにある1億個以上の天体の位置と明るさを測定します. さらに, そのうち で近くにある100万個の銀河の距離を決定し, 現在探索されているよりも100倍 大きな空間の3次元の地図を作ります.
