The European Space Agency's Gaia mission is publishing its third data release (DR3). The published catalogue of astronomical objects amounts to the most complete cosmic census to date, and is likely to have a decisive influence on astronomical research for years to come. Key information that is part of the survey, namely classification data that allows astronomers to readily search for objects such as stars, galaxies, or quasars, as well as physical information about stellar properties like temperature and chemical composition, were contributed by the Gaia group at the Max Planck Institute for Astronomy.
