Window into Space: The Parkes Radio Telescope (1965)

How does a radio telescope work? What do radio signals tell us about the Universe?

This film looks at the 210 ft. Radio Telescope at the Australian National Radio Astronomy Observatory, Parkes, New South Wales, showing some of the research made possible by the design of this complex radio aerial. Radio studies of the Large Magellanic Cloud and of the distant radio source, 3C-273, are mentioned briefly, while the study of magnetic fields in space and the distribution of hydrogen are explained in some detail. We begin to understand why it is that the more man learns about the Universe, the more questions there are to be answered.
