A week or so ago I posted a topic about methane(fluid) on titan. I asked a few questions but there was 1 that the astronomers couldn't answer:
Is life possible on the planet titan with its fluid methane(-180C`, circulating weather of methane)?
what is neccesary for life besides methane(fluid) and weather, by a temperature of -180C`? <-not co2 based but ch4 based.
