John Mather talks about Hubble and JWST

John Mather is the Project Scientist for the James Webb Space Telescope (JWST) – the new international space telescope which will launch later this decade. JWST will in many ways be a successor to Hubble, with greatly improved capabilities for infrared astronomy. In this interview, carried out at the “Science with the Hubble Space Telescope – III” conference in Venice, Italy, in October 2010, Mather talks about Hubble, JWST and some of his favourite scientific results. Portions of this video appear in Hubblecast episodes 41 and 42.
