A sonification of stellar catalogues through the history of astrometry, demonstrating the remarkable progress that has been made in the lead up to the first data release from ESA's Gaia mission.
The clip is a sampler, containing extracts from sonifications of the catalogues by Hipparchus of Nicaea (II century BC, handed down by Ptolemy); Ulugh Beg (1437); Tycho Brahe (1598); John Flamsteed (1725); JÃ©rÃ´me Lalande (1801); the Yale Trigonometric Parallax Catalogue (1995); and the Hipparcos Catalogue (1997).
The sonification of each catalogue lasts about 15 seconds in this clip; the various astronomical parameters provided in each catalogue were mapped into different dimensions in a soundscape.
