Dr. Porco believes that the icy moon, with its underground liquid sea of water, organics, as well as an energy source, may potentially host life similar to that found in analogous environments on Earth. The March 2012 images of Cassini's "tiger stripes" revealed that these cracks widen and narrow, as was suspected from pictures taken previously. The fissures also change over time more frequently than was originally thought. The two opposite sides of the fissures move laterally relative to one another. This is analogous to the way two banks of the San Andreas Fault can move forward and back, as well as in opposite directions. The greatest slipping and sliding happens when Enceladus is closest to Saturn--as scientists expected. Many people listen to the weather report on the radio before they head out the door in the morning so they can be prepared for the day to come. The influence of the moon on the Zodiac is a study in and of itself. When you are aware of your sun sign, you can use information about the cycles of the moon and the moon signs to determine the best time to make decisions or avoid certain activities. The moon signs are named the same as the Zodiac, but do not coincide with them.
