The "haze" of Titan

Original caption:"Looking back toward the sun brings out the thin haze that hovers 500 Km (310 miles) above Saturn's moon Titan.
The haze is composed of small particles whose diameter is comparable to the wavelength of light, which is ultraviolet light centered at 338 nnmts. Particles of this scale scatter sunlight most effectively in the direction opposite to the direction of sunlight itself.
Scientists are still trying to understand what processes produce this thin, high-altitude haze layer.

Picture data: North on Titan is up and tilted 10° to the right. The image was taken with the Cassini spacecraft narrow-angle camera on Sept. 24, 2005, at a distance of approx. 917.000 Km (about 570.000 miles) from Titan and at a Sun-Titan-spacecraft angle of 145°. Image scale is 5 Km (about 3 miles) per pixel".
