Gaia is a European space mission providing astrometry, photometry, and spectroscopy of nearly 2000 million stars in the Milky Way as well as significant samples of extragalactic and solar system objects. The Gaia ESA Archive contains deduced positions, parallaxes, proper motions, radial velocities, and brightness measurements.

Jan 15, 2025 · The best Milky Way map, by Gaia (artist impression) Open Image. Gaia has been charting the positions, distances, movements, brightness changes, composition and numerous other characteristics of stars by monitoring them with its three instruments many times over the course of the mission.. This has enabled Gaia to deliver on its primary goal of building the largest, most precise map of the ...
