Gaia is an ambitious 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 ...

Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025.
Gaia relies on the proven principles of ESA's Hipparcos mission to help solve one of the most difficult yet deeply fundamental challenges in modern astronomy: the creation of an extraordinarily precise three-dimensional map of about one billion stars throughout our Galaxy and beyond.
May 31, 2022 · Gaia is ESA’s mission to create the most accurate three-dimensional map of almost two billion stars throughout our galaxy and beyond, mapping their position, motion, brightness, temperature, and composition.
Dec 19, 2013 · Gaia is detecting celestial objects that are a million times fainter than the unaided human eye can see. For objects 4000 times fainter than the naked eye limit, Gaia is measuring their positions to an accuracy of 24 microarcseconds, comparable to measuring the diameter of a human hair at a distance of 1000 km. Gaia’s predecessor, Hipparcos ...
