US-SPACE-CASSINI-JET BLUE
This handout photo released 10 October 2007 courtesy of NASA shows a Cassini false-color view of individual jets spurting ice particles, water vapor and trace organic compounds from the surface of Saturn's moon Enceladus. The study, published in 11 October, 2007, issue of the journal Nature, identifies eight source locations, all on the prominent tiger stripe fractures, or sulci, in the moon's south polar region. Some of the sources occur in regions not yet observed by Cassini's composite infrared spectrometer, and researchers predict that future Cassini observations of those locations will find elevated temperatures. The images were acquired with the Cassini spacecraft narrow-angle camera on 27 November, 2005 at a distance of approximately 148,000 kilometers (92,000 miles) from Enceladus and at a sun-Enceladus-spacecraft, or phase, angle of 161 degrees. Scale in the original images is about 880 meters (0.5 mile) per pixel. This view has been magnified by a factor of two from the original images.
