Prometheus-PIA08947~0.jpgCosmic "Through-and-Through"!58 visiteCaption NASA:"Prometheus pulls away from an encounter with Saturn's F-Ring, leaving behind a reminder of its passage.
Prometheus (about 102 Km, or 63 miles across) approaches closely to the F-Ring once during each circuit around Saturn, disturbing the orbits of the small particles in the Ring and creating a streamer of material that then shears out, following the moon as it speeds off.
This view looks toward the unilluminated side of the Rings from about 37° above the Ring-Plane. Prometheus is brightly lit by the Sun on one side and lit more modestly by Saturn's reflected light on the other side.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 18, 2007 at a distance of approx. 2 MKM (about 1,2 MMs) from Prometheus and at a Sun-Prometheus-spacecraft, or phase angle of 87°. Image scale is roughly 12 Km (about 7 miles) per pixel".

Volcanic_Features-Apollinaris_Patera-PCF-LXTT.jpgApollinaris Patera (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)58 visiteThis Martian Volcano is found along the border between the ancient Martian Highlands and the younger Northern Lowlands.
It is characterized by a large caldera (~60 Km diameter), a basal scarp, and a large fan that emanates from the caldera and covers the Southern Flanks. Like other martian volcanoes it appears to have undergone episodes of both explosive and effusive eruptions. The color information in this mosaic of Apollinaris Patera comes from a series of color frames acquired by Viking 1 during orbit 468S (~350 m/pixel).
To sharpen details of morphology, the color mosaic was merged with a higher resolution (~180 mt/pixel) series of images acquired during orbit 088A.

Dione-N00119785.jpgCross-Worlds! (1)58 visiteI "lineamenti" superficiali di Dione sono inconfondibili; più difficile, invece, è l'individuazione del secondo Corpo Celeste che va ad incrociare Dione. Le immagini non sono perfette e la loro definizione è scarsa; tuttavia, applicando una notevole magnificazione, ci sembra di intravedere il bordo di un grande cratere, situato all'estremo Nord (dal punto di vista di Cassini - ergo dell'Osservatore) della seconda luna.
Si tratta, forse, del grande cratere Herschel, noto anche come "L'Occhio di Mimas".
Oppure, come suggerisce l'albedo della seconda luna, si potrebbe trattare di Encelado?
E Voi che ne dite?
In attesa che la NASA ci confermi o ci smentisca "l'ID" della seconda luna, le Vostre opinioni saranno profondamente apprezzate!MareKromium
