Enceladus

CS Monitor: Alluring Enceladus: How a tiny moon has kindled scientists' imagination - The Cassini spacecraft made its final flyby of Enceladus last week, leaving behind a Saturn moon that scientists are now clamoring to explore further in the search for life.

The probe has confirmed that a global ocean of liquid water exists beneath Enceladus’s icy surface, opening scientists' eyes to the possibility of oases for at least microbial life on tiny moons far from a planetary system's sun.
