NASA scientist Dr. Rosaly Lopes says that Titan, a moon of Saturn, may have cryovolcanoes.

Lopes has studied volcanoes on Earth, which spew hot, molten rock known as lava. Cryovolcanoes erupt with different materials. “These satellites have ice crusts,” she says. “And under the ice crusts, there is a layer of water, or perhaps water with something else like ammonia, and if that liquid can come to the surface, that is what we call cryovolcanism. It just means cold volcanism.”
