The green hue was a puzzle for astronomers in the early part of the 20th century because none of the known spectral lines at that time could explain it. There was some speculation that the lines were caused by a new element, and the name nebulium was coined for this mysterious material. With better understanding of atomic physics, however, it was later determined that the green spectrum was caused by a low-probability electron transition in doubly ionized oxygen, a so-called “forbidden transition”. This radiation was all but impossible to reproduce in the laboratory at the time, because it depended on the quiescent and nearly collision-free environment found in the high vacuum of deep space.

Titan has three large seas. However, the seas of Titan are not filled with water, but are filled instead with swirling liquid hydrocarbons. All three of Titan's exotic seas are close to its north pole, and they are surrounded by many smaller hydrocarbon-filled lakes in the northern hemisphere. She represents the inner woman we need to find expression for in our life as a woman or hints at what outer manifestation she will take for a man in his attraction to the feminine. What I discovered was that both the weather and moon were in my favor on my best days fishing. So basically I was fishing at the perfect time and didn't realize it. So then I began to wonder if I could use this information to my advantage. I figured out that I most certainly could use this information to my advantage by learning some simple tips about what the weather was doing and what phase the moon was in before I headed out onto the water.
