Saturn_s Clouds-V1-PIA00026_modest.jpgSaturn's Clouds from Voyager 155 visiteCaption NASA originale:"Two brown ovals, at right, some 10,000 kilometers (6,000 miles) across, were found at approximately 40` and 60` latitude in Saturn's northern hemisphere by Voyager l. The photo was taken on November 7, 1980, from a range of 7.500.000 Km. The polar oval (upper right) has a structure similar to the Saturn red spot located in the southern polar latitudes".

Saturn-V2-PIA00030_modest.jpgSaturn from approx. 33.900.000 Km - Voyager 254 visiteCaption NASA originale:"NASA's Voyager 2 took this 'true color' photograph of Saturn on July 21, 1981, when the spacecraft was 33.900.000 Km from the planet. Two bright, presumably convective cloud patterns are visible in the mid-northern hemisphere and several dark spoke-like features can be seen in the broad B-ring (left of planet). The moons Rhea and Dione appear as blue dots to the south and southeast of Saturn, respectively. Voyager 2 made its closest approach to Saturn on Aug. 25, 1981".

Saturn_s Clouds-HST-PIA01464_modest.jpgSaturn's Clouds from Hubble Space Telescope54 visiteCaption NASA originale:"This NASA Hubble Space Telescope image of the ringed planet Saturn shows a rare storm that appears as a white arrowhead-shaped feature near the planet's equator. The storm is generated by an upwelling of warmer air, similar to a terrestrial thunderhead. The east-west extent of this storm is equal to the diameter of the Earth (about 7,900 miles). Hubble provides new details about the effects of Saturn's prevailing winds on the storm. The new image shows that the storm's motion and size have changed little since its discovery in September, 1994".

Saturn_s Clouds-V2-PIA01958_modest.jpgSaturn's Clouds from Voyager 253 visiteCaption NASA originale:"In this Voyager 2 observation of Saturn’s northern mid-latitudes is seen a strangely curled cloud attached by a thin ribbon to the bright white cloud region to the north. The cloud has been monitored for seven rotations around the planet. It appears to be forming a closed loop. Other discrete clouds are seen to the east. Also evident is the “ribbonlike” structure at 47 north latitude in the white cloud region. The spacecraft took this image from a distance of about 9.300.000 Km".

A - Saturn_s sky before the Streak (2).jpgSaturn's Sky just before the "Streak" (2) - N00008769161 visiteDato che riteniamo di essere stati i primi ad individuare questa notevole Anomalia (la quale, peraltro, difficilmente, verrà riconosciuta come tale dalla NASA o dalle altre Agenzie Spaziali coinvolte nel Progetto Cassini/Huygens) riteniamo giusto rivendicare il nostro buon diritto di Scopritori e, quindi, la battezziamo con il nome di "Saturn-Cass/Huy-PCF-1-05/08/2004-Anomaly".

Janus from Voyager 2.jpgJanus from Voyager 257 visiteGiano, un'altra (fra le tante...) Lune Minori di Saturno.
Ma Voi sapevate chi era Giano, nella Mitologia Romana? Era - ovviamente - una Divinità il cui compito (decisamente delicato) era quello di vegliare sulle "Porte del Paradiso".
Il "Guardiano della Dimora degli Dei", insomma.
Da non dimenticare, infine, il fatto che Gennaio è proprio il mese dell'anno che deve a Giano (Janus) il suo nome.
