The geologically active moon, discovered in 1789 by William Herschel, has craters, ridges and smooth plains. Most spectacularly, Enceladus has geysers that spew frozen water thousands of kilometres into space.
This striped, mottled moon of Saturn gets even cooler.
Know what causes those geysers?
Well, at least in part, it’s the gravitational pull of Saturn itself. The massive gas giant exerts so much force on Enceladus that it distorts the moon’s crust, cracking it open and squeezing out water from the poles in the form of geysers.
