On 24 February a supernova blazed out in the Large Cloud of Magellan, which is the brightest of the external star-systems though unfortunately too far south to be seen from Britain. The new supernova is the brightest to have been seen since 1604, and is of immense interest to astronomers. Patrick Moore and Dr Paul Murdin of the Royal Greenwich Observatory talk about the supernova, and what it may tell us about the life-stories of the stars.
