Titan's Volcanoes...

Saturn’s moon Titan has lakes on its surface and a thick atmosphere, but there’s one more way this cold, distant world is like the Earth: It appears to have volcanoes—though they’re a little chillier than Eyjafjallajökull.

The surface of Titan is nearly -300 degrees F, and the cryovolcano could be erupting water ice and ammonia.
