Shown here is a spacecraft floating through the amazing cryo geysers on the south pole of Saturn´s moon Enceladus.
These geysers (discovered by the Cassini spacecraft in 2005) are formed along cracks in the moons icy surface and shoot powerful jets of - amongst other stuff - water vapor and ice particles into space. Some of the plumes reach heights of several hundreds of kilometers, and while most of it falls back as "snow" on the surface, some particles are shot into space and become part of the famous Rings of the parent planet of Saturn.
The geysers are one of many hints that there are large bodies of liquid water under the surface of the moon, making Enceladus a prime target for the search for extraterrestrial life in the Solar System.
The photo I used for the background was taken by NASA/CICLOPS with the Cassini spacecraft in 2005 and can be seen in its original form here
. For the texture of the moon I took some liberties and tweaked parts of this
beautiful composite of the full body of the moon, also by the Cassini spacecraft.
