Ghostly details make this dark scene more than just a beautiful grouping of two moons. In Titan's thick and distended atmosphere, the detached high haze layer can be seen, as well as the complex northern polar hood (at top). Images like this one can help scientists make definitive estimates of the altitudes to which the high haze extends.
Between Titan and Tethys (horizontally) is the very faint apparition of Saturn's G ring, just discernable above the level of background noise in the image.
The faint vertical banded pattern here is a type of noise that usually is removed during image processing. Because this image was processed to enhance the visibility of details in Titan's atmosphere and the faint G ring, the vertical noise was also enhanced.
Titan is Saturn's largest moon, at 5,150 kilometers (3,200 miles) across; Tethys is 1,062 kilometers (660 miles) across.
The view was obtained in visible light with the Cassini spacecraft narrow-angle camera on Jan. 19, 2006, at a distance of approximately 2.4 million kilometers (1.5 million miles) from Titan and 1 million kilometers (600,000 miles) from Tethys. The image scale is 14 kilometers (9 miles) per pixel on Titan and 6 kilometers (4 miles) per pixel on Tethys.
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.
