Another Dimension: 3D visualisation redefines Milky Way's local architecture 16 November 2015 Astronomers have used modern techniques to visualise data from ESA's Hipparcos space astrometry mission in three dimensions. Read more
Unique to Europe was the very first space mission for measuring the positions, distances, motions, brightness and colours of stars - for astrometry, as the experts call it. ESA's Hipparcos satellite pinpointed more than 100 000 stars, 200 times more accurately than ever before. As astrometry has been the bedrock of the study of the Universe since ancient times, this leap forward has affected every branch of astronomy. The primary product from this pioneering and successful mission was a set of stellar catalogues, The Hipparcos and Tycho Catalogues, published by ESA in 1997.

Query the Hipparcos & Tycho Catalogues 12 February 2004 Several research tools have been developed to facilitate access to data from the Hipparcos and Tycho Catalogues, and the Tycho-2 catalogue. Read more
Hipparcos Star Globe 02 October 2007 The Hipparcos Star Globe depicts the celestial sphere that was astrometrically viewed as a whole for the first time by the Hipparcos satellite. It is a projection of the night sky onto an icosahedron (a polyhedron with 20 triangle faces), highlighting especially bright stars and the constellations. Printed onto two sheets of A4 paper, the globe can be assembled to form a 3D star map that fits in the palm of your hand. Read more
