Cryovolcanism Quotes

One of the jovian moons, Europa, is coated with twice as much liquid water as is sloshing around our planet.

As far as Europa goes, Europa very likely has an ocean under its surface. In that regard, Europa and Enceladus are on equal par. But on Europa, the ocean is at least several kilometers under the surface, and the moon is bathed in an intense radiation field.

It's always snowing at the south pole of Enceladus.

Titan has rivers and lakes of liquid methane and ethane, methane weather systems of clouds and storms that mirror Earth's hydrologic cycle, and seasonal cycles that rival Earth's in complexity.

Liquids may have existed on the surface of Pluto in the past.

The most exciting thing that we have found with Cassini is the geological activity, the geysering activity at the south pole of Enceladus.

We're pretty sure there's plenty of organic material on Pluto. The atmosphere is largely methane, and in sunlight, methane builds organic molecules. We see reddish stuff on the surface that we think is organic material.

Even by the diverse standards of Saturn's satellites, Enceladus was an outlier. Its icy surface was as white and bright as fresh snow, and whereas the other airless moons were heavily pocked with craters, Enceladus was mantled in places with extensive plains of smooth, uncratered terrain, a clear sign of past internally driven geologic activity.

The geysering on Enceladus is the most astonishing phenomenon we have in our solar system.
