Cassini spots possible ice volcano on Saturn moon

The international Cassini spacecraft has spotted what appears to be an ice volcano on Saturn’s planet-size moon, a finding that may help explain the source of Titan’s thick atmosphere.

Infrared images snapped by the orbiting Cassini reveal a 20-mile-wide dome that appears to be a cryovolcano, a volcanic-like vent that spews forth ice instead of lava. Scientists theorise the volcano at one time spat out icy plumes that released methane into Titan’s atmosphere.
