The Gaia mission, which mapped 2 billion stars, was conducted by the European Space Agency (ESA). The mission concluded on January 15, 2025, after 12 years of operation due to the depletion of its cold gas propellant. Gaia provided the most detailed 3D map of the Milky Way, uncovering insights into galactic collisions, star clusters, and black holes. Launched in December 2013, Gaia operated around the Sun-Earth L2 Lagrange point, approximately 1.5 million kilometres from Earth, offering an unparalleled view of our galaxy.
