With its primary mirror measuring metres in diameter, the European Space Agency's Herschel telescope is the largest space telescope ever built; larger than the Hubble telescope which has a diameter of metres. Photographed at the Astrium site of the European Aeronautic Defence and Space Company (EADS) in Toulouse, France.
