  "description": "ESA's Gaia mission is a global space astrometry mission that built the largest, most precise three-dimensional map of our Galaxy by surveying nearly two billion objects. Launched on 19 December 2013 and operating from the Sun–Earth L2 Lagrange point, Gaia precisely charted the positions, distances, motions, brightness, and chemical compositions of stars throughout the Milky Way and beyond. Over its operational lifetime (27 July 2014 – 15 January 2025), the spacecraft made more than three trillion observations, achieving astrometric accuracy down to 24 microarcseconds — comparable to measuring the diameter of a human hair at a distance of 1000 km. Beyond stellar cartography, Gaia discovered exoplanets, brown dwarfs, asteroids, supernovae, and quasars, while providing stringent tests of general relativity. Its legacy is an unprecedentedly rich multi-dimensional catalogue of the cosmos, processed by the Gaia Data Processing and Analysis Consortium (DPAC) and released in successive data releases.",
