Cassini Images Halo Around Titanic Moon Off Saturn
Pasadena CA (SPX) Dec 27, 2005 With its thick, distended atmosphere, Titan's orange globe shines softly, encircled by a thin halo of purple light-scattering haze. Images taken using blue, green and red spectral filters were used to create this enhanced-color view; the color images were combined with an ultraviolet view that makes the high-altitude, detached layer of haze visible. The ultraviolet part of the composite image was given a purplish hue to match the bluish-purple color of the upper atmospheric haze seen in visible light. Small particles that populate high hazes in Titan's atmosphere scatter short wavelengths more efficiently than longer visible or infrared wavelengths, so the best possible observations of the detached layer are made in ultraviolet light. The images in this view were taken by the Cassini narrow-angle camera on May 5, 2005, at a distance of approximately 1.4 million kilometers (900,000 miles) from Titan and at a sun-Titan-spacecraft, or phase, angle of 137 degrees. Image scale is 8 kilometers (5 miles) per pixel. Related Links Cassini at JPL Cassini Image Team SpaceDaily Search SpaceDaily Subscribe To SpaceDaily Express
Multiple Cassini Instruments Capture Enceladus Plume Pasadena CA (JPL) Dec 17, 2005 Cassini observations by several instruments have revealed the source of Saturn's broadest and faintest ring. Recent observations show that tiny particles of frozen water ice are streaming outward into space from the south polar region of the moon Enceladus. |
