Welcome to the October edition of the AstroPod! This month the Director of the IoA and recent recipient of the Gruber prize, Prof. Rob Kennicutt, tells us all about the exciting key project from the Hubble Space Telescope that accurately measured the expansion rate of our universe and its age. Anna's feature this month delves into the history of the Plumian Professorship held here at Cambridge and the outstanding astronomers that have filled the role over the centuries. And of course we have Alex with the Sky at Night and Michelle with your monthly installment of astro-comedy gold! Sit back, enjoy and don't forget you can find more info on our website at http://www.ast.cam.ac.uk/astropod
