Life beyond Earth? Dame Maggie Aderin-Pocock on the mysteries of space

Dame Maggie Aderin-Pocock is a space scientist and science educator who has worked on a number of instruments that are revolutionising our view of the cosmos, including the James Webb Space Telescope. This year she will be giving the Royal Institution Christmas lectures, Britain’s most prestigious public science lectures, in which she will be exploring some of the big questions space science still has to answer. Nicola Davis sat down with Dame Maggie to discuss the lectures, why she is convinced there is life beyond our planet, and her dream of journeying to a distant exoplanet. Madeleine Finlay hears from them both in this Christmas special edition of Science Weekly..
