Enceladus is Saturn's sixth-largest moon, but despite being a mere 500 km in diameter is known to be geologically active. Enceladus has an extensive system of cryovolcanoes at its south polar region where liquid water incorporating dissolved oceanic salts escape from fault lines in the moon’s surface and out into space. The geysers eject more than 200 kg of material every second which freezes instantly in the cold vacuum of space forming bright crystals of ice and salt which contribute to Saturn's E-ring. The Cassini spacecraft flew directly through these plumes in 2005 allowing its instruments to directly "taste" the moon’s interior. The composition of the plumes were found to be very similar to that of most comets in fact, being composed mostly of water, various inorganic salts, and organics such as methane, carbon monoxide, acetylene, formaldehyde, and others. Beyond proving that Enceladus harbors a hidden liquid ocean, the Cassini flybys also found another possible home for simple alien life in our Solar System.
This scene depicts the view of the icy spires of Enceladus a few hundred kilometers from the moons frozen surface. Saturn hovers peacefully in the background as the little moon's geysers fire snow and ice into space - and just maybe any unfortunate inhabitants of the hidden ocean that strayed too close to the open fissures.
I used Vue to generate the texture for Enceladus and Photoshop for everything else in this image.
