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.
Michael Perryman awarded prestigious Tycho Brahe Prize 06 June 2011 Professor Michael Perryman, the scientific leader of ESA's Hipparcos mission, and a founding father of its successor mission, Gaia, has been awarded the 2011 Tycho Brahe Prize from the European Astronomical Society. Read more
Science@ESA: Episode 6: Charting the Galaxy - from Hipparcos to Gaia 15 October 2009 In this sixth episode of the Science@ESA vodcast series Rebecca Barnes discovers the motions of the stars, learns how astronomers measure their distances and looks at the new European mission that will really get to grips with our place in the Universe.

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
