What will the end of days actually look like? And how will it happen? This month, Izzie and Dr Becky explore the end of the Universe with cosmologist Dr Katie Mack - author of The End of Everything (Astrophysically Speaking). They also chat to astronomy journalist and author of The Unknown Universe, Dr Stuart Clark, who explains the role of dark energy. Plus, Dr Robert Massey takes on your questions and shares when it is best to see Jupiter, Saturn and Venus in December.

Send your astronomy questions for January's Q&A to podcast[@]ras.ac.uk or tweet @RoyalAstroSoc.
