Voyager to Uranus

The Voyager 2 probe by-passed the planet Uranus on 24 January. Though discovered in 1781, not much had been found out about Uranus - in many ways a mysterious world, with a strange axial tilt and a system of dark rings. Patrick Moore is at the space headquarters in Pasadena for the encounter, and in this programme he is joined by the leading NASA experts to give the latest news and pictures of what Voyager 2 has to tell us about this mysterious green world.
