Public lecture - Friday 10th Feb - Wills Memorial Building



"Our solar system is a blend of the effluvia from many stellar explosions. By making high precision isotope ratio measurements on different meteorites we have been able to fingerprint the source of the most recently added material. We identify a supernova component from a massive star, which is in keeping with a longstanding hypothesis for triggered nebula collapse and subsequent planetary
growth."
