Pre-solar. Meteorites can tell us a surprising amount about our solar system and its environment. In this episode we talk to Ernst Zinner about his studies of pre-solar grains from meteorites [00:53-26:17]. As always we put your questions to Dr Tim O'Brien [27:37-41:56] and round-up the feedback we've received since the last show. We also chat about Jodcast Live!
