Enceladus, Saturn's Amazing Snowball Moon

Saturn’s sixth-largest moon, Enceladus (504 kilometers or 313 miles across), is the subject of much scrutiny, in large part due to its spectacular active geysers and the likelihood of a subsurface ocean of liquid water. NASA’s Cassini orbiter has studied Enceladus, along with the rest of the Saturnian system, since entering orbit in 2004. Studying the composition of the ocean within is made easier by the constant eruptions of plumes from the surface, and on October 28, Cassini will be making its deepest-ever dive through the ocean spray from Enceladus—passing within a mere 30 miles of the icy surface. Collected here are some of the most powerful and revealing images of Enceladus made by Cassini over the past decade, with more to follow from this final close flyby as they arrive.
