Germany's Carl Zeiss Optronics has signed a contract to supply the optical system for two instruments to be installed on the James Webb Space Telescope; the successor to the Hubble Space Telescope. Due for launch in 2013 on board an Ariane rocket, the telescope will be stationed at a stable position in space called the Lagrangian point L2. JWST will be cooled down to -230 degrees Celsius so that it's highly sensitive infrared instruments can peer through clouds of gas and dust.
