The journal "Historia y Vida" has published this month an article about the Gaia mission and the history of astrometry. ICCUB researcher Josep Manel Carrasco has collaborated in it.
It describes the evolution of astrometry: since ancient times, when people used the positions of celestial objects to guide themselves; to the Gaia mission by the European Space Agency, which will provide during the next five years the largest compilation of positions and motions of stars ever.
