This day-side photo of Titan taken by the Cassini spacecraft shows a buildup of haze over the Saturn moon's south pole (bottom). Cassini has found a build up of haze over the 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.
