Titan is the largest moon of Saturn (6th planet from Sun), discovered in 1655. It is about 5,150 km/3,198 mi in diameter and has a significant atmosphere that is composed mainly of nitrogen.

NASA has recently published the image of hemisphere of (half-lit) Titan shown above. This image “was taken with the Cassini spacecraft narrow-angle camera on July 14, 2013 using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers.”

North side on Titan is up and rotated 32 degrees to the left.

From NASA,

“The sunlit edge of Titan’s south polar vortex stands out distinctly against the darkness of the moon’s unilluminated hazy atmosphere. The Cassini spacecraft images of the vortex led scientists to conclude that its clouds form at a much higher altitude — where sunlight can still reach — than the surrounding haze.”

The view was taken from a distance of about 808,000 miles (1.3 million kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 82 degrees.
