In this season on life in the universe, it's time to look closer to home: what are the chances we will find evidence of life — present or past-tense — in the Solar System, our own back yard? Emily's fabulous colleague Dr Clément Moissard, plasma physicist at the University of York, joins us to discuss the search for life on Mars, on the icy moons of Jupiter and Saturn ... even on Pluto?! Surely not. It's a fascinating and fun conversation with plenty of surprises: Chris somehow missed the fact that we landed on Titan in 2005, Clément is super keen to visit mysterious Planet 9, and Emily just seems fixated on tasty space fish.
