In the last Jodcast of 2007 Ken Kellermann and Dave Jauncey tell us about the discovery of quasars, particularly the lunar occultations of 3C 273 in the early 1960s. Jodcast newcomer Roy Smits gives us a summary of the Jodrell Bank Illuminate Art event and we ask your astronomical questions to Dr Edward Boyce.
