Coming up in this month's Christmas episode: The Christmas elves have visited the AstroPod and insisted on a festive theme so we bring you news of Santa tracking, along with a discussion of the possible astrophysical explanations of the Star of Bethlehem. Our interview this month is with Dr Mark Wyatt about debris disks - the remains of planet formation such as the asteroid belt in the Solar System, and how they help us learn about other planet systems. We also have our usual news round up, the latest from events in Cambridge and of course the astronomy joke of the month. Sit back, enjoy and don't forget you can find more info on our website, just click the link in iTunes!
