...Ring of Fire... (natural colors; elab. Lunexit)

Caption NASA:"This celestial circle of light is produced by the glow of Sunlight scattered through the periphery of Titan's atmosphere as the Sun is occulted by Titan. It is the sum of all the sunsets and sunrises taking place on Titan at once.

The intriguing structure of Titan's North Polar "hood" can be seen at upper left.
A thin, detached, high-altitude global haze layer encircles the moon.
North on Titan is up and rotated 23° to the left.

The image was taken in visible blue light with the Cassini spacecraft wide-angle camera on June 29, 2007. The view was obtained at a distance of approx. 210.000 Km (about 131.000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 167°.
Image scale is roughly 12 Km (about 8 miles) per pixel".
