Carme Jordi, Gaia researcher at ICCUB, will talk about Gaia results at the X edition of the Encuentros Transfronterizos de Astrónomos Aficionados (RTAA) : «Arte y Ciencia: punto de encuentro y creatividad». The encounters RTAA organise activities to share astronomy among people interested in astronomy from both sides of the Pyrenees, also including this year a British asociation. The RTAA basis are the cooperation "Pro-Am" (Professionals-amateurs), and the opening up to all kind of audiences, young and adults, as well as the interaction among different cultures, disciplines and languages.
