Prehistorische culturen waren al gefascineerd door de manier waarop de sterren, planeten en kometen zich aan de hemel voortbewThe space astrometry mission Gaia, planned for launch in 2013 by the European Space Agency (ESA), will provide the most comprehensive and accurate catalogue of astrometric data for galactic and astrophysical research in the coming decades. It will observe roughly one billion stars, quasars and other point like objects for which the five astrometric parameters (position, parallax and proper motion)
