What is the origin of the methane detected in Enceladus’s plumes? A Bayesian approach to the problem shows that abiotic serpentinization of rocks cannot explain the methane abundance by itself, and biotic methane production gets the highest likelihood—provided the probability of life emerging at Enceladus is high.
