Gaia – Mapping a Billion Stars

20 September 2013

Royal Aeronautical Society


You can listen to this lecture here, or visit the Society's 'SoundCloud' to listen to a range of past lectures.

The European Space Agency’s (ESA) Hipparcos satellite improved our knowledge of the position and velocity of 120,000 stars by two orders of magnitude in the 1990s and ESA’s Gaia satellite is due to repeat that feat for a billion stars (see diagram).  Due for launch in November, Gaia contains the largest imaging detector ever flown in space (built by Britain’s e2v) and it will also detect tens of thousands of planets around other stars, of near-Earth asteroids and of supernovas in distant galaxies.  This is the most exciting of the world’s space science launches in 2013 and it will be described by ESA’s Gaia Project Manager, Giuseppe Sarri.
