Speckles of Light

The stars, many far bigger than our ' star the sun, are many millions of miles away and appear only as specks of light. Until recently it had been impossible to see any details of the stars. But thanks to a new technique called 'speckle interferometry' this can be done for the first time. Patrick Moore discusses the remarkable results with Professor Alec Boksenberg , Director of the The Royal Greenwich Observatory, Herstmonceux.
