This discovery is a major one. This could mean that there is life on this moon! Maybe not intelligent life, but the odds of life other than on Earth, existing in our solar system, have just gotten lower. Even if there is no life there, it increases the chances again for more planets outside our solar system to contain life or vast oceans of water.

NASA Cassini Spacecraft Captures Ocean-Like Spray At Saturn Moon

WASHINGTON -- NASA's Cassini spacecraft has discovered the best evidence yet for a large-scale saltwater reservoir beneath the icy crust of Saturn's moon Enceladus. The data came from the spacecraft's direct analysis of salt-rich ice grains close to the jets ejected from the moon.

Data from Cassini's cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. But closer to the moon's surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an "ocean-like" composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. The findings appear in this week's issue of the journal Nature.

"There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus's icy surface," said Frank Postberg, a Cassini team scientist at the University of Heidelberg, Germany, and the lead author on the paper. When water freezes, the salt is squeezed out, leaving pure water ice behind. If the plumes emanated from ice, they should have very little salt in them.

Jason,
The whole universe is full of life, and intelligent life just like us humans here on earth. Its just that mainstream science chooses not to acknowledge it.

Oh I couldn't agree more. I am just eager to see what is actually down there. I can imagine an entire ecosystem of creatures. It would be amazing to find something to the level of mammals. The probability is high too. Organic material was also found in samples taken from the geysers: Cassini Tastes Organic Material at Saturn's Geyser Moon

2008: NASA's Cassini spacecraft tasted and sampled a surprising organic brew erupting in geyser-like fashion from Saturn's moon Enceladus during a close flyby on March 12. Scientists are amazed that this tiny moon is so active, "hot" and brimming with water vapor and organic chemicals.

It goes on to mention stuff about comets, though we have yet to actually see a comet or sample one that is made of ice or snow etc.

The Ion and Neutral Mass Spectrometer saw a much higher density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected. This dramatic increase in density was evident as the spacecraft flew over the area of the plumes.
