Unusually-looking_Surface_Feature-S22-00831d-01.jpgPossible Surface Anomaly (EDM - False Colors)75 visiteA questo (super) ingrandimento, l'ipotesi che si possa trattare di un image-artifact svanisce totalmente: si tratta, effettivamente, di una Regione "ricoperta" da qualcosa. Qualcosa di bianco e di brillante.
Qualcosa che, con ogni probabilità, è effettivamente "ghiaccio".
Ma come ci è arrivato in quel punto? E perchè solo in quel punto?
Domande, domande, domande...

Prometheus-PIA08849.jpgThe "Wave-Maker"...75 visiteCaption NASA:"Prometheus dips into the inner F-Ring at its farthest point from Saturn in its orbit, creating a dark gore and a corresponding bright streamer. Gores created during previous apoapsis (the name for the farthest point in an orbit) passes, are seen above. The older gores are farther behind the moon in its orbit of Saturn. This view looks toward the unlit side of the Rings from about 31° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 1, 2006 at a distance of approx. 1,7 MKM (about 1,1 MMs) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 162°.
Image scale is roughly 10 Km (a little more than 6 miles) per pixel".
Nota: si tratta di una elaborazione Lunexit in falsi colori che abbiamo realizzato per evidenziare non solo la reale forma di Prometheus ma anche la presenza, sia internamente, sia esternamente all'Anello "F", di una debolissima luminosità (che appare di colore rosso scuro) la quale, a nostro parere, NON è un semplice effetto ottico - tipo luce diffusa dall'Anello "F" - bensì è vero e proprio materiale: la porzione più estrema (esterna ed interna) dell'Anello "F" stesso la quale è formata, con ogni probabilità, solo da polveri.MareKromium

Psp_001808_1875_red.jpgSlope Streaks (or "Seeps"?) in Terra Sabaea75 visiteSlope streak formation is among the few known processes currently active on Mars. While their mechanism of formation and triggering is debated, they are most commonly believed to form by downslope movement of extremely dry sand or very fine-grained dust in an almost fluidlike manner (analogous to a terrestrial snow avalanche) exposing darker underlying material. Other ideas include the triggering of slope streak formation by possible concentrations of near-surface ice or scouring of the surface by running water from aquifers intercepting slope faces, spring discharge (perhaps brines) and/or hydrothermal activity.
Several of the slope streaks visible here, particularly the 3 longest darker streaks, show evidence that downslope movement is being diverted around obstacles such as large boulders. Several streaks also appear to originate at boulders or clumps of rocky material.
In general, the slope streaks do not have large deposits of displaced material at their downslope ends and do not run out onto the crater floor suggesting that they have little reserve kinetic energy. The darkest slope streaks are youngest and can be seen to cross cut and superpose older and lighter-toned streaks. The lighter-toned streaks are believed to be dark streaks that have lightened with time as new dust is deposited on their surface.
