Astronomy & Astrophysics, published by EDP Sciences, has published a special issue on the second data release (DR2) of the Gaia space mission which has been recording astrometric and photometric measurements since July 2014.

Gaia is an astrometric space observatory developed by the European Space Agency. It is devoted to measuring the position, distance and movement of stars. Gaia DR2 is based on the analysis on the first 22 months of the mission and the data release gives an insight into its full potential. It represents “a game-changing leap for stellar and Galactic astronomy” ( Forveille, T., Kotak, R., Shore, S. and Tolstoy, E., A&A 616, E1 (2018) ).
