BBC Horizon Encounter with Neptune

A journey following the NASA Voyager space probe which travelled from Earth to Jupiter, Saturn, Uranus & Neptune during the late 1970s and 1980s. This documentary examines the discoveries made by the probe about each of the planets and their large collection of moons using real photographs and computer animations (often primitive, such was the technology available back then).

'Encounter With Neptune' examines the discoveries of the planet Neptune and its geologically active moon Triton.
