Discussion on Earth getting a ring, Enceladus jets, and tectonic activity

It's FINALLY happening. Izzie is letting Dr Becky have an entire episode about her favourite planet, Saturn. 

Professor Geraint Jones from UCL's Mullard Space Science Laboratory tells the Supermassive Team about the Saturnian system. Plus, Professor John Zarnecki shares his experiences of being involved with the Cassini-Huygens mission. And, as always, Dr Robert Massey is on hand to take on listener questions and share his stargazing tips for the month. 

The Supermassive Podcast is a Boffin Media production for The Royal Astronomical Society by Izzie Clarke and Richard Hollingham.
