Merry Christmas from the AstroPod Crew! This month, Dr George Becker from the Institute of Astronomy talks to us about cosmic climate change and our new historian, first year PhD student Alex Hall, tells us about the history of quasars. Of course this episode is also packed with the latest news from the world of astronomy and Alex Caverley tells us what we can currently see in the Sky At Night, while Michelle entertains us with a festive joke of the month.
