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. On July 20, 1969, astronaut Neil Armstrong radioed back from the surface of the Moon, "... the Eagle has landed". Most of us believe that the landing occurred as broadcast. Not all, however. More than 30 years after the fact, Fox TV aired "Conspiracy Theory: Did We Really Go to the Moon?". In doing so, the Fox entertainers unleashed a lively cabal of kooks and NASA-bashers on a scientifically naive audience without benefit of editorial balance. Polls suggest that perhaps 6% of Americans believe in the authenticity of these claims. Comets are actually bright, streaking invaders from far, far away that carry within their mysterious, frozen hearts the most pristine of primordial ingredients that contributed to the formation of our Solar System about 4.6 billion years ago. This primeval mix of frozen material has been preserved in the pristine "deep-freeze" of our Solar System's darkest, most distant domains. Comets are brilliant and breathtaking spectacles that for decades were too dismissively called "dirty snowballs" or "icy dirt balls", depending on the particular astronomer's point of view. These frozen alien objects zip into the inner Solar System, where our planet is situated, from their distant home beyond Neptune. It is generally thought that by acquiring an understanding of the ingredients that make up these ephemeral, fragile celestial objects, a scientific understanding of the mysterious ingredients that contributed to the precious recipe that cooked up our Solar System can be made.
