With Jerzy back from holiday, we talk about the possibility of life out in space and inside future robots. Along the way, we stop off at Pluto, Charon, Kepler-452b and SETI's newest incarnation 'Breakthrough Listen'. We also discuss the potential implications of autonomous weaponry, following a warning letters from individuals such as Elon Musk and Steven Hawking.
