The New Infra-red Telescope

This month an important new British telescope has been completed. It is destined to be set up in Hawaii, and it is not an ordinary telescope; it is designed to study infra-red radiation from space, which cannot be seen directly but which is all-important in modern science. Professor Vincent Reddish , Astronomer Royal for Scotland, describes the Hawaiian telescope, and Patrick Moore talks to Professor James Ring about its likely role in infra-red astronomy.
