Structure of Enceladus. Cutaway artwork showing the interior of Enceladus,the sixth largest of Saturn's moons. Saturn is at lower right. The surface of Enceladus is thought to be a thick layer of water ice (light blue) covering the hard rocky interior. Geologic activity and tidal heating melts this ice to produce water (dark blue) which can rise to the surface through cracks in the ice. Polar jets have been observed on Enceladus,due to 'water volcanism' (cryovolcanism). Jets are shown spouting from fissures in the ice. Enceladus is 504 kilometres in diameter,with a mean surface temperature of 75 Kelvin (minus 198 degrees Celsius) | |
