Seen from outside, #Enceladus appears to be like most of its sibling moons: cold, icy and inhospitable. But under that forbidding exterior may exist the very conditions needed for life. Over the course of the Cassini mission, observations have shown that Enceladus (313 miles or 504 kilometers across) not only has watery jets sending icy grains into space; under its icy crust it also has a global ocean, and may have hydrothermal activity as well. Since scientists believe liquid water is a key ingredient for life, the implications for future missions searching for life elsewhere in our solar system could be significant. 📸 by @NASA’s #Cassini mission. #photography #blackandwhite #space #engineering #Saturn #science #NASA #ESA #JPL #NASABeyond @nasasolarsystem
