Saturn from approx. 9.000.000 Km (2).jpgWhat is this?!? (1)59 visiteEsistono centinaia di immagini negli archivi relativi alle raw-images della Sonda Cassini-Huygens che riprendono oggetti imprecisati che si trovano nello Spazio di Saturno. Nella maggior parte dei casi si tratta dei Satelliti (Maggiori e Minori) del Pianeta o di particelle cosmiche (raggi cosmici, forse) che lasciano strane tracce (punti e strisce). In altri casi, la risposta è lasciata al buon senso ed alla prudenza di chi guarda. Secondo noi questa luce è il Satellite Rhea, sovraesposto. E secondo Voi?...

Saturn-HST-PIA05982_modest.jpgSaturn from Hubble Space Telescope59 visiteCaption NASA originale:"...The subtle pastel colors of ammonia-methane clouds trace a variety of atmospheric dynamics. Saturn displays its familiar banded structure, with haze and clouds at various altitudes. Like Jupiter, all bands are parallel to Saturn's equator. The magnificent rings, at nearly their maximum tilt toward Earth, show subtle hues which indicate the trace chemical differences in their icy composition..."

Saturn_s Clouds-V1&V2-PIA01375_modest.jpgSaturn's Clouds from Voyager 1 and Voyager 259 visiteCaption NASA originale:"This comparison shows Saturn’s north temperate region as viewed on Nov. 5, 1980, by Voyager 1 (left) and Aug. 21, 1980, by its sister craft, Voyager 2, from a range of 5.000.000 Km; the large bright oval feature in the lower right of each frame measures about 2.500 Km. The largest bright feature in the Voyager 1 photograph extends about 7.500 Km from north to south. These giant storms lie within one of the strongest westward-flowing currents observed in the atmosphere, with wind speeds of about 20 mt p/s".

Saturn_s Clouds-V2-PIA01379_modest.jpgSaturn's Clouds from Voyager 259 visiteCaption NASA originale:"A vortex, or large atmospheric storm, is visible at 74` north latitude in this color composite of Voyager 2 Saturn images obtained on Aug. 25, 1980, from a range of about 1.000.000 Km. This particular storm system seems to be one of the few large-scale structures in Saturn's polar region, which otherwise is dominated by much smaller-scale features suggesting convection. The darker, bluish structure (upper right) oriented east to west strongly suggests the presence of a jet stream at these high latitudes".
