ikenbot:  Saturn Moon Titan's Atmosphere Shows Surprising Rise  Saturn's cloudy moon Titan has a middle atmosphere containing organic compounds that could hold the potential for life. Now, a new look at that atmospheric layer by a NASA spacecraft shows that it may be on the move, scientists say.  Image: This night-side photo of Titan taken by the Cassini spacecraft shows a buildup of haze over the Saturn moon's south pole (bottom). New results from Cassini's infrared spectrometer show that air is now sinking at the south pole, leading to increased temperatures at high altitude and a large enrichment in trace gases.

Because of Titan's seasonal orientation, the winter poles always point away from Earth, hiding on the moon's dark side. Studying the complex trace gases in the visible summer hemisphere doesn't solve the problem; water vapor in Earth's atmosphere obscures the measurements of the trace gases.
