Anyone see the Open Uni programme on Friday night?
(yes, instead of being out on the razz, I was in fact lying in bed watching a tv programme about a mission to Titan - a claim to geekdom?)
Someone suggested that below the crust of Titan is a salty ocean, and a geologically active core that could drive geothermal vents in very much the same way as seen in Earth's oceans and very possibly Europa's too.
Could a liquid, warm ocean fed by volcanic activity harbour life of some kind, a billion miles from here?
