The Centre de Données astronomiques de Strasbourg (CDS; English translation: Strasbourg Astronomical Data Centre) is a data centre which collects and distributes astronomical information . It was established in 1972 under the name Centre de Données Stellaires by the National Institute of Astronomy and Geophysics (INAG). The on-line services currently provided by the CDS include:
- SIMBAD, a database of astronomical objects. It's the main service for the identification and bibliography of astronomical objects, vizier, which collects astronomical catalogs and tables published in academic newspapers, and Aladdin, an interactive atlas of the sky that allows to visualize astronomical images from the soil and spatial observatories or supplied by the user, and data from CDS services or other databases such as NED.
