Pan-PIA08230.jpgInside "Encke"...56 visiteCaption NASA originale:"Hiding within the Encke Gap is the small moon Pan, partly in shadow and party cut off by the outer A-Ring in this view. Similar to Atlas, Pan appears to have a slight ridge around its middle; and like Atlas, Pan's orbit also coincides with a faint ringlet. Pan is 26 Km(about 16 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 30, 2006 at a distance of approximately 269.000 Km (such as about 167.000 miles) from Pan. Image scale is roughly 2 Km(approx. 5.259 feet) per pixel".

Saturn-PIA08227.jpgA shadow's over Saturn!58 visiteCaption NASA originale:"The shadow of Epimetheus, one of Saturn's co-orbital moons, races across the Planet's restless cloud tops. Epimetheus cruises along beyond the orbits of the narrow F-Ring and its shepherd moons.
Farther south on Saturn, the swirls and eddies are obscured by the shadow of the outer A-Ring and its two prominent, moon-containing gaps, Encke (bottom) and Keeler (dim, at the A-Ring edge).
The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of infrared light centered at 728 nnmts. The view was obtained on June 30, 2006, from a distance of approximately 335.000 Km (about 208.000 miles) from Saturn.
Image scale is approx. 16 Km (a little less than 10 miles) per pixel".

Saturn&Friends-PIA08220.jpgOne in the Shadows, one in the Lights58 visiteCaption NASA originale:"The unlit side of the Rings glows with scattered Sunlight as two moons circle giant Saturn. The light reaching Cassini in this view has traveled many paths before being captured.
At left, Mimas (397 Km, or 247 miles across) presents its "Dark Side". Enceladus (505 Km, or 314 miles across), on the Far Side of the Rings, is lit by "Saturnshine," or reflected sunlight coming from the planet. Saturn, in turn, is faintly lit in the south by light reflecting off the Rings.
Saturn's shadow darkens the Rings, tapering off toward the left side of this view.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 11, 2006 at a distance of approx. 3,9 MKM (about 2,5 MMs) from Mimas, 4,3 MKM (approx. 2,7 MMs) from Enceladus and 4,1 MKM (about 2,6 MMs) from Saturn.
Image scale is roughly 25 Km (approx. 16 miles) per pixel on Saturn".

Enceladus-PIA08217.jpgThe "Sprayer" under the Rings57 visiteCaption originale:"Enceladus blasts its icy spray into space in this unlit-side Ring view that also features a tiny sliver of Rhea.
The South Polar Region of Rhea (dim.: 1.528 Km, or about 949 miles across) peeks out from beneath the Rings to the right of Enceladus (dim.: 505 Km, or about 314 miles across).
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 9, 2006 at a distance of approx. 3,9 MKM (about 2,4 MMs) from Enceladus and 4,6 MKM (such as about 2,9 MMs) from Rhea. The Sun-Enceladus-spacecraft, or phase, angle is 161°. Image scale is about 23 Km (approx. 14 miles) per pixel on Enceladus".

Enceladus&C-PIA08216.jpgJewels...59 visiteThe real jewels of Saturn are arguably its stunning collection of icy moons. Seen here with the unlit side of the Rings are Titan (Dx), Tethys (Sx) and Enceladus (Cn) with its fountain-like geysers.
The faint, vertical banding in the image is due to "noise" in the spacecraft electronics. This noise is difficult to remove from an image that has a very wide dynamic range - i.e.: a wide range of brightness levels - as in the difference between gleaming Titan and the faint plumes of Enceladus.
Additionally, a reflection of Titan's light within the camera optics is likely responsible for the faint secondary image of Titan's limb to the left of the giant moon.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on June 10, 2006 at a distance of approx. 3,9 MKM (about 2,4 MMs) from Enceladus; 5,3 MKM (about 3,3 MMs) from Titan and 4,4 MKM (such as approx. 2,7 MMs) from Tethys.
The phase angle is 160° on Enceladus.
Image scale is 23 kilometers (14 miles) per pixel on Enceladus, 32 kilometers (20 miles) per pixel on Titan and 26 kilometers (16 miles) per pixel on Tethys.

Mimas-PIA08215.jpgMimas, in the Night of Saturn...56 visiteCaption originale:"Cassini looked toward the Night Side of Saturn to spy the darkened orb of Mimas barely visible here near the center of the image hugging the Planet's shadow. To the left of Mimas are several bright features in the faint D-Ring.
The innermost of Saturn's medium-sized icy moons, Mimas, is 397 Km (about 247 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 7, 2006 at a distance of approx. 3,9 MKM (such as about 2,4 MMs) from Mimas and 4 MKM (about 2,5 MMs) from Saturn. The Sun-Mimas-spacecraft, or phase, angle is 161°.
Image scale is approx. 24 Km (about 15 miles) per pixel on Saturn".
