This is an ultraviolet image of Titan's night-side limb, colourised to look like true colour. The many fine haze layers extend several hundred kilometres above the surface. Although this is a night-side view, with only a thin crescent receiving direct sunlight, the haze layers are bright from light scattered through the atmosphere.
The image was taken with the Cassini-Huygens narrow-angle camera. About 12 distinct haze layers can be seen in this image, with a scale of 0.7 kilometres per pixel. The limb shown here is at about 10 degrees south latitude, in the equatorial region.
