Uranus - the Second Ringed Planet?

For centuries the ringed planet Saturn has been regarded as unique. This year the startling discovery has been reported that Uranus also has a system of rings - though as yet they have not been seen directly. Patrick Moore discusses this new development with Gordon Taylor, of the Royal Greenwich Observatory. who has made special studies of Uranus, and Dr Garry Hunt, who is closely involved with plans for Voyager, the unmanned space-craft due to bypass Uranus in the 1980s.
