2025-01-15
ESA's Gaia spacecraft has completed its decade-long sky survey, amassing over three trillion observations of roughly two billion stars and other celestial objects. This represents a revolutionary leap in our understanding of the Milky Way and our cosmic neighborhood. Despite nearing fuel depletion, Gaia's data continues to grow, fueling scientific research with over 13,000 publications and 580 million catalogue accesses to date. Two more massive data releases are yet to come, promising further revelations about the universe.
