The Gaia satellite is dedicated to astrometry and was launched by ESA in 2013 to map our galaxy in 3D.

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…
