Smiling Titan...

This infrared view shows features on the Leading Hemisphere of Titan, including the bright, crescent-shaped Hotei Arcus (right of center), which is also informally called "the Smile" by researchers.
The view is centered on the bright Region called Xanadu. Above center is the large crater Minerva, which is surrounded by darker material.

This image was taken with the Cassini spacecraft narrow-angle camera on Jan. 13, 2006 using a spectral filter sensitive to wavelengths of infrared light centered at 938 nnmts. The image was acquired at a distance of approx. 1,3 MKM (800.000 miles) from Titan and at a phase angle of 41°. Image scale is about 7 Km (approx. 5 miles) per pixel.
