NASA’s Cassini spacecraft on November 2nd, 2005 saw, what is one of the brightest objects in that region of the solar system; become the only geologically active outer planetary moon. Most moons are geologically dead, but on Enceladus geysers of water and ice spew into the atmosphere, from its South Pole region where the geographic feature known as tiger stripes are, were caught flying miles high into space at about 1,400 miles per hour by Cassini. It is now believed that this shimmering moon holds liquid water and that the Cryovolcanism is the process that is used to describe this process. Scientist want to know why it is active as infrared maps show warm surface temperatures cause by the geysers as the heated liquid water comes out from inside the moon and turns into ice due to the surrounding space in the area which is cold. What makes this moon a wonder is its mystery of how much water does it hold. As to how this moon heats its water, guesses by scientist suggest that it may be from radioactive elements which decay and heat up the interior which would keep the water in a liquid state. The more accepted explanation is tidal mechanism heating, which is cause by the force of gravity exhorted by Saturn on the moon from the very eccentric elliptical orbit of the moon. This means that when Enceladus is closest to Saturn, friction causes the water to heat up and cracks in its icy South Pole tiger stripes allow the water to shoot into space. Now since water can host life, could there be life on Enceladus and what kinds of life forms would they be like? These basic questions are what make Enceladus wonder number seven.
