About Gaia Sky

Gaia Sky is free, open-source 3D visualization software built for ESA's Gaia mission, which charts about one billion stars in the Milky Way. Users can navigate the galaxy in real time, filter stars by properties, and load additional catalogs of asteroids, exoplanets and spacecraft. Researchers, planetariums and space fans use it to explore real survey data rather than artist impressions.
