Saturn-PIA08936.jpgA Planetary "Smile", from Saturn...57 visiteCaption NASA:"Brooding Saturn seems to be missing its rings, but their shadows on the Planet betray their presence. The inner rings are in fact contained within this scene, but they are so tenuous as to be nearly invisible.
This view looks toward the unilluminated side of the Rings from about 52° above the Ring-Plane. Some motion is apparent in Saturn's clouds between the exposures used to create this color composite, as evidenced by the 'rainbow' effect seen here and there across the face of the Planet.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were taken with the Cassini spacecraft wide-angle camera on April 5, 2007 at a distance of approx. 1,5 MKM (about 900.000 miles) from Saturn.
Image scale is roughly 84 Km (about 52 miles) per pixel".MareKromium

Saturn-PIA08939.jpgCandy Stripes56 visiteCaption NASA:"This strongly enhanced false color view is a departure from the familiar bluish North and golden South seen in natural color Cassini spacecraft images, but the contrast between regions north and South of the Ring shadows is here more readily apparent.
The Northern Region is marked by a multitude of bright, patchy clouds.
The Region south of the Ring shadows contains the bright equatorial band seen in many monochrome Cassini views taken at infrared wavelengths (see PIA07590).
Taken just minutes after PIA08936, this view makes Saturn's Rings faintly visible at lower left. The false color enhancement brings out additional detail in the Planet's clouds that is not visible in the natural color view.
This view looks toward the unilluminated side of the Rings from about 52° above the Ring-Plane".MareKromium

Saturn-PIA08942.jpgDeep Blue (IR view of the Rings)54 visiteThe Cassini spacecraft surveys Saturn's outstretched Ring System in the infrared from a vantage point high above the Planet's Northern Latitudes. Nearly the full expanse of the main rings is visible here -- from the C-Ring to the outer edge of the A-Ring (in the upper left corner).
Ring shadows are visible on the planet at lower left, and two large storms swirl near center.
This view looks toward the unilluminated side of the Rings from about 52° above the Ring-Plane.
The image was taken with the Cassini spacecraft wide-angle camera using a combination of spectral filters sensitive to wavelengths of infrared light centered at 752 (red channel), 890 (blue channel) and 728 (green channel) nanometers.
The view was acquired on April 5, 2007 at a distance of approx. 1,4 MKM (about 900.000 miles) from Saturn. Image scale is roughly 81 Km (approx. 51 miles) per pixel.MareKromium

Saturn-PIA08944-00.jpgPrometheus Makes Contact (natural colors - elab. NASA)58 visiteCaption NASA:"The F-Ring shepherd moon Prometheus touches the face of Saturn once more before moving off into blackness and continuing in its orbit.
The F-Ring itself is visible as a thin line just below Prometheus (which is about 102 Km, or approx. 63 miles across).
This view looks toward the unilluminated side of the Rings from about 18° above the Ring-Plane. North on Saturn is up and rotated about 30° to the right.
Images taken using red, green and blue spectral filters were combined to create this natural color view.
The images were obtained by the Cassini spacecraft narrow-angle camera on April 13, 2007 at a distance of approx. 1,7 MKM (such as a little more than 1 MMs) from Prometheus and 1,8 MKM (such about 1,1 MMs) from Saturn.
Image scale is roughly 10 Km (6 miles) per pixel".MareKromium

Saturn-PIA08952.jpgThe Southern Latitudes of Saturn54 visiteCaption NASA:"Stunning details in Saturn's clouds suggest movement within bands of atmosphere. This false color enhancement makes visible an exciting level of detail in the bright and dark bands that is more easily seen at Jupiter than at Saturn.
Saturn's Southern Hemisphere seems to fade into the blackness of space in this view.
The image was taken with the Cassini spacecraft wide-angle camera using a combination of spectral filters sensitive to wavelengths of infrared light centered at 752 (red channel), 890 (blue channel) and 728 (green channel) nanometers.
The view was acquired on Feb. 2, 2007 at a distance of approx. 1 MKM (such as about 600.000 miles) from Saturn.
Image scale is roughly 57 Km (about 36 miles) per pixel".MareKromium

Saturn-PIA08973.jpgIR Saturn54 visiteCaption NASA:"Cassini looks toward Northern Latitudes on Saturn and out across the Ring-Plane.
This InfraRed (IR) view probes clouds beneath the hazes that obscure the Planet's depths in natural color views.
This image looks toward the unilluminated side of the Rings from about 24° above the Ring-Plane. The Rings' shadow drapes across the region North of the Planet's bright Equatorial Band.
The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of light centered at 890 nanometers. The view was acquired on May 24, 2007 at a distance of approx. 1,5 MKM (such as about 1 MMs) from Saturn.
Image scale is roughly 89 Km (55 miles) per pixel".MareKromium

Saturn-PIA08982.jpgIn the Night...63 visiteCaption NASA:"Graceful giant Saturn poses with a few of the small Worlds it holds close. From this viewpoint the Cassini Spacecraft can see across the entirety of the Planet's shadow on the Rings, to where the Ring-Plane emerges once again into Sunlight.
Tethys shines large and bright near the bottom of the scene. Pandora sits outside the F-Ring, below center. Epimetheus is a speck on the far side of the Ring-Plane, immediately to the right of Saturn's limb. Most of the other bright specks near the Rings are background stars.
This view looks toward the unilluminated side of the Rings from about 8° above the Ring-Plane. The image has been brightened to enhance the appearance of the small moons.
The image was taken with the Cassini spacecraft wide-angle camera on June 2, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 918 nanometers.
The view was obtained at a distance of approx. 2,2 MKM (such as about 1,4 MMs) from Saturn.
Image scale is roughly 131 Km (about miles) per pixel".MareKromium

Saturn-PIA08983.jpgSpokes!54 visiteCaption NASA:"The Cassini Spacecraft spies multiple spokes in Saturn's outer B-Ring. The precise origin and evolution of these transient features continue to provide Ring Scientists with intriguing puzzles to solve.
Most of these spokes are about 4000 Km long; the 2 near the bottom of the scene are about 1000 Km (about 600 miles) wide.
This view looks toward the unilluminated side of the Rings from about 8° above the Ring-Plane.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on June 2, 2007. The view was acquired at a distance of approx. 2,2 MKM (such as about 1,4 MMs) from Saturn.
Image scale is roughly 13 Km (about 8 miles) per pixel".MareKromium
