The Sky at Night celebrates one of the most profound, moving and enjoyable activities there is - the ancient art of looking up, studying and marvelling at the night sky. The programme is based at the Royal Observatory, Greenwich - the spiritual home of British astronomy - and sets out to discover the many and varied ways we can all enjoy the majesty of the skies. Maggie Aderin-Pocock travels to Norway to see the northern lights, and discovers that we are in a golden age of aurora research as she learns what they tell us about the solar system. Chris Lintott learns the ancient art of navigating by the stars, whilst Pete Lawrence helps choose the right equipment to set yourself up as an amateur astronomer. This is your guide to observing and enjoying all the Wonders of the Night Sky.
