Titan's UV Haze

Looking back toward the Sun brings out the thin haze than hovers 500 kilometers (310 miles) above Titan. The haze is composed of small particles whose diameter is comparable to the wavelength of light, which is ultraviolet light centered at 338 nanometers. Particles of this scale scatter sunlight most effectively in the direction opposite to the direction of sunlight. Scientists are still trying to understand what processes produce this thin, high altitude haze layer.

North on Titan (5,150 kilometers, 3,200 miles across) is up and tilted 10 degrees to the right.

The image was taken with the narrow angle camera on Sept. 24, 2005 from a distance of approximately 917,000 kilometers (570,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 145 degrees. Image scale is 5 kilometers (3 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
