Two of the great autumn constellations of Andromeda and Pegasus will soon be gracing our night skies. The maiden Andromeda, chained to her rock, awaits her fate whilst the winged horse Pegasus gallops across the celestial skies. Full of interesting stars, nebulae and galaxies, these constellations are rich pickings for astronomers.

The outer limits of the solar system are a dark, cold and mysterious place, which only the Voyager spacecraft have visited. Sir Patrick Moore discusses the ice giants Uranus and Neptune, while Chris Lintott has an early Christmas treat - a lost episode of The Sky at Night from 1963 which has been returned to the BBC, in which Arthur C Clarke talks about his vision of bases on the moon and speculates when man will be on Mars.
