Saturn-PIA09917.jpgFrom farther North, than the North Pole...57 visiteCaption NASA:"Myriad vortices churn through Saturn's high Northern Latitudes while Dione's shadow drifts across the gas giant's face.
This view looks toward the unilluminated side of the Rings from about 43° above the Ring-Plane.
The image was taken with the Cassini Spacecraft wide-angle camera on May 7, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers.
The view was obtained at a distance of approx. 1,2 MKM (about 760.000 miles) from Saturn. Image scale is roughly 69 Km (about 43 miles) per pixel".MareKromium

Saturn-PIA09913.jpgJust a Matter of "Proportions"...58 visiteCaption NASA:"A great, eye-like vortex stares out of Saturn's roiling atmosphere. The storm is wide enough to span the distance from Washington, DC to London. Bright Enceladus drifts past in the foreground.
This view looks toward the unilluminated side of the Rings from about 3° above the Ring-Plane.
The image was taken with the Cassini Spacecraft wide-angle camera on April 23, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 752 nanometers. The view was acquired at a distance of approx. 1,3 MKM (such as about 783.000 miles) from Saturn.
Image scale is roughly 72 Km (about 45 miles) per pixel".MareKromium

Saturn-PIA09908.jpgThrough the Rings...59 visiteCaption NASA:"The Cassini spacecraft peers through the Gossamer Strands of Saturn's innermost rings, whose own shadows adorn the Planet beyond.
This view looks toward the sunlit side of the rings from about 35° below the Ring-Plane. The image was taken in visible light with the Cassini Spacecraft wide-angle camera on April 21, 2008. The view was obtained at a distance of approximately 620.000 Km (approx. 385.000 miles) from Saturn.
Image scale is roughly 67 Km (approx. 42 miles) per pixel".MareKromium

Saturn-PIA09910.jpgThe "Head" of Saturn (Natural Colors; credits: NASA/Space Science Institute)57 visiteCaption NASA:"Bright puffs and ribbons of cloud drift lazily through Saturn's murky skies. In contrast to the bold red, orange and white clouds of Jupiter, Saturn's clouds are overlain by a thick layer of haze. The visible cloud tops on Saturn are deeper in its atmosphere due to the Planet's cooler temperatures.
This view looks toward the unilluminated side of the Rings from about 18° above the Ring-Plane. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft wide-angle camera on April 15, 2008 at a distance of approx. 1,5 MKM (such as about 906,000 miles) from Saturn.
Image scale is roughly 84 Km (about 52 miles) per pixel".MareKromium

Atlas-PIA09818.jpgIn the Night...62 visiteCaption NASA:"Two of Saturn's ring moons draw close momentarily, before the inner of the pair moves off alone.
Atlas passes Prometheus (about 86 Km, or approx. 53 miles across, at center left) about once a month, then slowly and steadily pulls ahead of its slower moving sibling.
This view looks toward the unilluminated side of the Rings from about 23° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 6, 2008. The view was acquired at a distance of approx. 1,6 MKN (such as about 975.000 miles) from Atlas.
Image scale is roughly 9 Km (about 6 miles) per pixel".MareKromium

Daphnis-PIA09902.jpgDaphnis and a Little Star...59 visiteCaption NASA:"The Cassini Spacecraft captures a view showing two of Saturn's moons and their gravitational effects on nearby Rings.
At top, Daphnis (about 8 Km, or 5 miles across at its widest point) streaks through the Keeler Gap, with its ever-present edge waves. At center, Prometheus (about 86 Km, or 53 miles across at its widest point) pulls away from a recent encounter with the F-Rring. A bright background star is visible below the F-Ring.
This view looks toward the unilluminated side of the Rings from about 41° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 8, 2008. The view was acquired at a distance of approx. 1,3 MKM (such as about 788.000 miles) from Prometheus and at a Sun-Prometheus-Spacecraft, or phase, angle of 53°.
Image scale is roughly 8 Km (about 5 miles) per pixel".
Nota Lunexit: noi vediamo Daphnis, la "Piccola Stella" in basso rispetto all'Anello "F" e la scia lasciata da Prometheus (sull'estrema Sx del frame) a seguito del suo transito ma, di Prometheus...nessuna traccia! E Voi? Lo vedete Prometheus?MareKromium

Mimas-PIA09880.jpgMimas is on Sight!58 visiteCaption NASA:"The Cassini spacecraft looks toward the high north on heavily cratered Mimas. The unmistakable Herschel impact crater is seen at lower left.
Lit terrain seen here is on the anti-Saturn side of Mimas (397 Km, or about 247 miles across).
Nota Lunexit: osservate bene la linea che disegna il profilo visibile di Mimas (se over-saturate il frame il lavoro sarà perfetto) e quindi notate la forma vagamente ovoidale di questa piccola luna.
Ed è proprio nella forma non sferica, comunque, che si cela la differenza tra "corpo celeste planetario" (piccolo o grande non importa) e "planetoide".
The moon's North Pole is up and tilted slightly toward Cassini. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 11, 2008. The view was acquired at a distance of approx. 795.000 Km (about 494.000 miles) from Mimas and at a Sun-Mimas-Spacecraft, or Phase, angle of 88°.
Image scale is roughly 5 Km (about 3 miles) per pixel".MareKromium

Atlas-PIA09885.jpgAtlas and the "Roche Division"58 visiteCaption NASA:"Atlas, seen here, is one of the two moons that ply the Roche Division -- the region between Saturn's A and F-Rings. Prometheus also orbits within this Division.
This view looks toward flying-saucer-shaped Atlas (32 Km, or about 20 miles across at its widest point) and the unilluminated side of the Rings from about 37° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 9, 2008. The view was obtained at a distance of approx. 1,5 MKM (such as about 925.000 miles) from Atlas and at a Sun-Atlas-Spacecraft angle of 44°.
Image scale is roughly 9 Km (approx. 6 miles) per pixel".MareKromium

(natural colors; credits: Lunexit)61 visiteCaption NASA:"Caption NASA:"N00107152.jpg was taken on April 10, 2008 and received on Earth on April 11, 2008. The camera was pointing toward SATURN, F-RING that, at the time, was approx. 611.114 Km away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated".MareKromium

Janus-PIA09871.jpgJanus and Saturn (natural colors; credits: Lunexit)58 visiteCaption NASA:"The Cassini Spacecraft provides a window on the awesome scale of the Saturn System, with the Giant Planet dominating one of its smaller satellites.
Orbiting here, just outside the Main Ring System, is Janus.
This view looks toward the unilluminated side of the Rings from about 16° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 13, 2008. The view was obtained at a distance of approx. 1,6 MKM (about 1 MMs) from Janus and approx. 1,8 MKM (about 1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel on Janus".MareKromium
