Stefan Posted April 6, 2014 Hello, flickr | Brickshelf GAIA is a space telescope of the European Space Agency ESA which surveys the position, distance and motion of about 1 billion stars (~1% of our Galaxy), creating a 3D map of the Milky Way with unprecedented precision. To carry out its measurements, GAIA is equipped with two reflective telescopes with a focal lenght of 35 m and the biggest camera flown into space to date.
