Rainstorms on Titan may be assembling one of life’s earliest structures without liquid water: a 2025 NASA-backed study proposes that splashes from its methane-and-ethane lakes create coated droplets which acquire a second molecular layer as they fall back, forming the same kind of bilayer compartments that preceded Earth’s first cells.

A proposed Titan rain-splash mechanism uses two organic-coated interfaces to close a hydrocarbon droplet into a bilayer compartment, but every critical step remains testable.
