Aside from the monthly phases of the moon, there is also a daily lunar effect on fish feeding habits. Moonrise and moonset appear to be very good times to go fishing, if other factors like the weather are cooperative. Studies show that fish are more active 90 minutes before and after either the moonrise or moonset. Given this, you now know when is a good time to go fishing, provided it fits your schedule!
Titan's atmosphere is approximately 95% nitrogen. However, in a way that dramatically differs from Earth's own mostly-nitrogen atmosphere, Titan's atmosphere has very little oxygen. Indeed, the remainder of Titan's atmosphere is almost entirely composed of methane--along with small qunatities of other gases, such as ethane. At the extremely cold temperatures that are found at Saturn's great distance from the heat of our Star, Titan's methane and ethane can accumulate on its icy surface to form pools of liquid.
"We don't know how long the Dagwood-sandwich structure would exist. This structure represents a stable state, but various factors could mean the moon doesn't reach this stable state," Dr. Christophe Sotin said in a May 1, 2014 statement. Dr. Sotin is of the JPL.
