SDSS Sky Server

The SDSS Sky Server is an online portal developed by the Sloan Digital Sky Survey (SDSS) that provides public access to a vast collection of astronomical data collected by its surveys. It offers interactive tools to view sky images, explore spectra, and query catalogues of celestial objects, such as stars, galaxies, and quasars. With an intuitive interface and resources catering to both enthusiasts and professional researchers, Sky Server also provides ways to access data through SQL queries, facilitating custom analyses directly on the SDSS database.

LIneA hosts a mirror of SDSS Sky Server (skyserver.linea.org.br), where it provides access to release DR17 data.
