Gaia is an ambitious ESA mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group.
The CDS is a partner data centre for the publication of the Gaia Data Release 1. On September 14, 2016 the Gaia DR1 will be available in the CDS services Vizier, Aladin and the CDS catalogue cross matching service. The inclusion of these data into the CDS makes them interoperable with all of the CDS reference data including more than 14000 catalogues and hundreds of image surveys. Aladin and Aladin Lite visualisers provide an all-sky hierarchical view of the entire GDR1 data set, using the capabilities of CDS HiPS (Hierarchical Progressive Surveys) technologies.
Gaia DR1 is also made available from the CDS via Virtual Observatory protocols (IVOA Cone Search, and Table Access Protocol).
The image shows an all-sky view of the density map of the billion Gaia sources.
The CDS is a reference data centre with joint authorities of CNRS-INSU and the Université de Strasbourg. CDS is a member of Gaia DPAC CU9 This work was supported by the CNES. It is based on observations with Gaia mission.
