The precise chemical composition of these very alien lakes and seas remained unknown until 2014, when Cassini's radar instrument detected Ligeia Mare, now known to be Titan's second-largest hydrocarbon-filled lake. Ligeia Mare is brimming with an abundance of sloshing methane, and this enormous liquid reservoir is approximately the same size as two of Earth's Great Lakes combined--Lake Michigan and Lake Huron. Many planetary scientists think that the seabed of Ligeia Mare may be blanketed with a thick layer of sludge that is composed of organic-rich compounds.
Cassini wasn't originally designed to spot signs of life in the Enceladus plume. In fact, planetary scientists didn't even know that the plume existed until after the spacecraft reached Saturn.
In Western astrology, the Sun represents who we are in the world, the outward projection of our personality, and the mark we wish to make. By contrast, the moon governs our emotions, our primal instincts, and our unconscious mind. It represents a feminine energy, and is often personified as a goddess or mother. In other words, those deep intuitive urges-those passionate feelings we can't quite describe-are embodied in the moon. No wonder so many love poems have been penned under the influence of its rays!
