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. A New Moon is when the moon takes its monthly promenade and reaches the phase where it comes to rest between the sun and Earth, in this position the moon's dark side is facing us making it seem 'invisible'. As of December 2015, confirmed liquid water in our own Solar System--excluding Earth--accounts for about 25 to 50 times the volume of our planet's water. The moons of our Sun's family thought to possess liquid water are:
