"Cassini's seven-plus years... have shown us how beautifully dynamic and unexpected the Saturn system is," commented project scientist Dr. Linda Spilker of NASA's JPL to Time Magazine's online edition on March 23, 2012.
Europa: Planetary scientists generally think that a layer of liquid water swirls around beneath Europa's surface, and that heat from tidal flexing causes the subsurface ocean to remain liquid. It is estimated that the outer crust of solid ice is about 6 to 19 miles thick, including a ductile "warm ice" layer that hints that the liquid ocean underneath may be 60 miles deep. This means that Europa's oceans would amount to slightly more than two times the volume of Earth's oceans.
This does not mean that soul mates must always have strong lunar contact in their birth charts. The compatibility between Moon signs is another important factor. Each of the 24 possible combinations (for example, his Leo Moon combined with your Aquarius Moon, or your Virgo Moon combined with his Sagittarius Moon) presents its own emotional chemistry.

Beyond just a physical or intellectual attraction, lunar energy signifies a deep and psychic bond between lovers.
