Titan is the only place besides Earth with stable liquid on its surface, a working weather cycle and complex organic chemistry — and now, according to 2025 NASA research, a plausible mechanism for building the first membrane around a primitive cell, without liquid water involved.

A 2025 proposal gives methane rain a role in assembling cell-like membranes on Titan, but every step from surface film to stable vesicle remains untested. The post Titan is the only place besides Earth with stable liquid on its surface, a working weather cycle and complex organic chemistry — and now, according to 2025 NASA research, a plausible mechanism for building the first membrane around a…
