Titanian "Bands"

Caption NASA:"Titan bears a distinct East-West banded pattern in this Cassini spacecraft image taken in the ultraviolet.
The ultraviolet wavelength allows Cassini to see Titan's stratosphere, where superrotation -- in which the atmosphere moves around the moon faster than Titan rotates -- is strong. The recent appearance of this feature may be a harbinger of seasonal change on Titan.

The moon's halo -- its detached, high-altitude global haze layer -- is visible here as well, and is often its most prominent feature in such ultraviolet views. North on Titan is up and rotated 6° to the right in this image.

The view was obtained by the Cassini spacecraft narrow-angle camera using a spectral filter sensitive to wavelengths of polarized ultraviolet light.
The view was acquired on Dec. 25, 2006 at a distance of approx. 1,3 MKM (about 800.000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 123°.
Image scale is roughly 8 Km per pixel".
