Saturn's moon Titan could harbor life, but only a tiny amount
Despite its rich inventory of organic molecules, Saturn's largest moon may be able to support only a minuscule amount of biomass, if life exists there.
Covered in rivers and lakes of liquid methane, icy boulders and dunes of soot-like "sand," its topography has long fascinated scientists and invited speculation on whether lifeforms might lurk beneath the moon's thick, hazy atmosphere. "In our study, we focus on what makes Titan unique when compared to other icy moons: its plentiful organic content," said Affholder, who is a postdoctoral research associate. At the core of the research lies a "back-to-basics" approach that attempted to come up with a plausible scenario for life on Titan that assumed one of the simplest and most remarkable of all biological metabolic processes: fermentation.
