Finding out whether there is actually life beneath that alien ice means we are going to have to send some sort of aquatic spacecraft over there. Astrobiologists from Paris Sciences & Letters University and the University of Arizona led a study recently published in
Nature Astronomy, and while study lead Antonin Affholder believes more investigation is needed here, extraterrestrials shouldn’t be ruled out yet.
“After simulating hydrothermal vents on Enceladus, our results show that the most plausible scenarios correspond to a relatively high dihydrogen concentration in serpentinization fluids, similar to what we have on Earth,” Affholder told SYFY WIRE, “but it is still hard to compare conditions on Earth and Enceladus.”

TUCSON, Ariz. An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn s moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences & Lettres University.
Giant water plumes erupting from Enceladus have long fascinated scientists and the public alike, inspiring research and speculation about the vast ocean that is believed to be sandwiched between the moon s rocky core and its icy shell. Flying through the plumes and sampling their chemical makeup, the Cassini spacecraft detected a relatively high concentration of certain molecules associated with hydrothermal vents on the bottom of Earth s oceans, specifically dihydrogen, methane and carbon dioxide. The amount of methane found in the plumes was particularly unexpected.
