A haze of methane enshrouds Saturn's largest moon, Titan, and prevents scientists from seeing most sunlight reflections off the surface. But NASA's Cassini orbiter
managed to snap a stunning image of sunlight glinting off a huge, liquid methane lake -- a smoking gun that confirms liquid in the northern hemisphere.
