Observing from La Silla

The Sky at Night – Season 33

High in the Andes mountains of Chile lies one of the world's major observatories, La Silla, with its 15 telescopes. Conditions there are ideal - far better than anywhere in Europe. In this programme Patrick Moore visits La Silla , talks to the astronomers there, and even has what may be his last view of Halley's Comet.
