Video taken by the Saturn-orbiting Cassini spacecraft reveals evidence of three volcanoes that appear to be gushing liquid water through the moon's icy surface. The activity could be a source replenishing the methane in Titan's atmosphere, which is broken down by sunlight

WATER WORLD: This image shows the location of an area known as Sotra Facula on Saturn's moon Titan. The black and white swaths show data obtained by the radar instrument on NASA's Cassini spacecraft. The swaths were laid on top of a global composite image from Cassini's visual and infrared mapping spectrometer. Scientists think the Sotra Facula region makes the best case for a cryovolcanic--or ice volcano--region on Titan. The area is located around 15 degrees south latitude, 40 degrees west longitude.Image: NASA/JPL-Caltech/University of Arizona
