The northern part of the moon’s atmosphere visible here includes the north polar hood, a cap of haze looking slightly darker than the rest of the atmosphere and seen near the top of the moon. See PIA08137 to learn more about the north polar hood.
The south polar vortex that first appeared in Titan’s atmosphere in 2012 is visible at the bottom of this view. The south polar vortex was not present earlier in the mission (see PIA08391 and PIA14909). Titan is 3,200 miles (5,150 kilometers) across.
A wide-angle view in today’s package captures Titan passing in front of Saturn, as well as the planet’s changing colors. Upon Cassini’s arrival at Saturn eight years ago, Saturn’s northern winter hemisphere was an azure blue. Now that winter is encroaching on the planet’s southern hemisphere and summer on the north, the color scheme is reversing: blue is tinting the southern atmosphere and is fading from the north.
