The Gaia satellite is dedicated to astrometry and was launched by ESA in 2013 to map our galaxy in 3D. A team of engineers and researchers from the Paris Observatory based in Meudon is taking part in this mission to try to find out the position and movement of the stars. The probe scans the universe continuously and sends a large amount of data a part of which is studied and analysed by the Observatory team. The results of the European Gaia mission are published in a catalogue and help us to understand how our galaxy was formed and may reveal the existence of new planets.
