Saturn Storms.jpgStorms on Saturn (refined)57 visiteCaption originale da "NASA - Picture of the Day" del giorno 02.11.2004:
"(...) scientists commanded the Cassini spacecraft (...) to inspect a circulating band of clouds nicknamed "Storm Alley". This westwardly moving cloud ring has been unusually active since the beginning of 2004, spawning white swirling storms and dark storms ringed by sprawling white clouds all cascading around the gas giant. The rogue band, as well as part other parts of south Saturn, were imaged in stunning detail in a very specific band of infrared light that passes through Saturn's upper haze relatively unblurred. The result was then digitally sharpened, showing more cloud detail but creating fake image artifacts such as a surrounding ring. Speculation on the nature of past Saturn storms included convective motions of small amounts of ammonia and water, seasons and shadowing effects of the Great Ring System. Although the above image provides data and clues, the power behind Saturn's storms still remains a mystery".

Saturn and Enceladus - PIA06483_modest.jpgSaturn and Enceladus (in ultra-violet)56 visiteCaption NASA originale:"Looking beyond Saturn's south pole, this was the Cassini spacecraft's view of the distant, icy moon, Enceladus on July 28, 2004. The planet itself shows few obvious features at these ultraviolet wavelengths, due to scattering of light by molecules of the gases high in the atmosphere. Enceladus is 499 Km wide.
The image was taken with the Cassini spacecraft narrow angle camera at a distance of 7.4 MKM from Saturn through a filter sensitive to ultraviolet wavelengths of light. The image scale is 44 Km per pixel of Saturn".

Saturn and Mimas-PIA06473.jpgSaturn and Mimas60 visiteCaption NASA originale:"On its first orbit of the ringed planet, the Cassini spacecraft gazed into the distance to capture this image of the icy moon Mimas (398 Km - 247 miles wide). The faint F-Ring is visible as the outermost strand of the rings in this view. The image was taken in visible light with the narrow angle camera on August 16, 2004, at a distance of 8.9 MKm (5.5 MMs) from Saturn. The image scale is 53 kilometers (33 miles) per pixel. Contrast was slightly enhanced to aid visibility".

Saturn and Prometheus-PIA06481_modest.jpgSaturn and Prometheus57 visiteCaption NASA originale:"Saturn's moon Prometheus is seen shepherding the inner edge of Saturn's "F-Ring". Prometheus is 102 Km across and was captured in a close-up view by the Cassini spacecraft near the time of orbital insertion at Saturn (see PIA06098). A number of clumps are visible here along the arcing "F-Ring".
The image was taken with the Cassini spacecraft narrow angle camera on Aug. 5, 2004, at a distance of 8.2 MKM from Saturn through a filter sensitive to visible green light. The image scale is 49 Km per pixel. Contrast was slightly enhanced to aid visibility".
