Enceladus: Evidence of a Global Ocean and Hydrothermal Vents, with the Prospect of Life and a Future Plume-Sampling Mission

To the point

Enceladus probably has a global ocean beneath its icy shell with hydrothermal vents that eject warm, mineral‑rich water through the ice, and the plume evidence—silica grains formed above 90 C, extra methane, and hydrogen—cited by Morgan Cable, Linda Spilker, Chris Glein, and Steve Vance points to a possible habitat for life and a future mission could sample the plume for signs of life.

Despite its tiny size and frozen surface, scientists now think Enceladus is capable of harboring life.
