Beneath the icy surface of Saturn's moon Enceladus lies a global oceanâand it may have all the ingredients necessary for life. This small moon has become one of the most exciting targets in the search for extraterrestrial organisms.
The Evidence
The Cassini spacecraft flew through geysers erupting from Enceladus's south pole and detected water vapor, organic molecules, and most importantly, molecular hydrogen. This hydrogen suggests hydrothermal activity on the ocean floorâthe same type of environment where life may have originated on Earth.
Future Missions
NASA and ESA are planning missions to return to Enceladus, including concepts for probes that could sample the geyser plumes in detail or even penetrate the ice to explore the ocean directly. These missions could answer one of humanity's oldest questions within our lifetimes.
If life exists on Enceladus, it would prove that biology can arise independentlyâsuggesting the universe may be teeming with organisms.
