Dione&Co.-PIA07679.jpgProportions, dimensions, perspectives and distances...56 visiteOriginal caption:" Two of Saturn's battered, icy companions hover here, above the Ring-Plane.
To get a sense of the three-dimensional nature of the scene, note that the wide band of visible Rings is in between the two moons in this view from the Cassini spacecraft.
Mimas (397 Km, or 247 miles across, at left) is outside the far side of the Rings while Dione (1.126 Km, or 700 miles across) is outside the Rings and closer to Cassini.
The view is from just beneath the Ring-Plane and the image was taken in visible light, with the Cassini spacecraft narrow-angle camera on Dec. 18, 2005, at a distance of approx. 2,2 MKM (roughly 1,4 MMs) from Dione and 2,7 MKM (about 1,7 MMs) from Mimas. The image scale is 13 Km (about 8 miles) per pixel on Dione and 16 Km (about 10 miles) per pixel on Mimas".Gen 21, 2006

Mimas-N00048622.jpgOver the clouds of Saturn: Mimas (2)62 visiteOriginal caption:"N00048613.jpg was taken on January 19, 2006 and received on Earth January 19, 2006. The camera was pointing toward Mimas that, at the time, was approximately 1.011.360 kilometers away, and the image was taken using the CL1 and CL2 filters.

Saturn-PIA07678.jpgNeon-lights in the night of Saturn75 visiteOriginal caption:"Like a rope of brilliant neon, Saturn's Rings outshine everything else in this night side view, while the sunlit southern face of the Rings reflects a dim glow onto the atmosphere below. When viewed nearly edge-on, the Rings often appear very bright.
Epimetheus and Janus are mere specks to the left of the Ring edge (and Epimetheus being the outermost of the pair).
The image was taken in visible light with the Cassini spacecraft wide-angle camera on Dec. 17, 2005, at a distance of approximately 2,7 MKM (such as about 1,7 MMs) from Saturn and at a Sun-Saturn-spacecraft angle of 75°. The image scale is about 164 Km (roughly 102 miles) per pixel". Gen 19, 2006

Saturn-PIA07673-br500.jpgLike a light in the darkness: Dione59 visiteThis moody portrait of Saturn captures a razor-thin Ring-Plane bisecting the clouds of the bright Equatorial Region. The Rings cast dark, shadowy bands onto the Planet's Northern Latitudes.
At left, Dione is a tiny sunlit orb against the Planet's Dark Side.
The image was taken in polarized infrared light with the Cassini spacecraft wide-angle camera on Dec. 7, 2005 at a distance of app.x 3,1 MKM (about 1,9 MMs) from Saturn and at a phase angle of 96°. Image scale is 179 Km (about 111 miles) per pixel.

Saturn-E-Ring-W00012982.jpgOver-exposed Moons and the E-Ring57 visiteEscludendo che i due globi luminosi che vediamo in questo frame (in una posizione di quasi allineamento rispetto all'Anello E di Saturno) sìano dei photi-artifacts o degli UFO, la nostra sensibilità nell'analisi dei frames in arrivo dalla Sonda Cassini ci suggerisce l'idea che si tratti di due Lune di Saturno ampiamente sovraesposte.
Ma se ci chiedeste di quali Lune si tratta...Beh, non ci vergognamo di dire che questo proprio non lo sappiamo.
Caption originale:"W00012982.jpg was taken on January 11, 2006 and received on Earth January 12, 2006. The camera was pointing toward Saturn's E-Ring that, at the time, was approximately 2.048.891 Km away.
The image was taken using the CL1 and IRP90 filters and has not been validated or calibrated". Gen 14, 2006

Saturn-PIA07674.jpgLooking for the "Hexagon"57 visiteOriginal caption:"As Northern Winter ends on Saturn and the Cassini spacecraft's view of the North Pole improves, the swirls and eddies visible until now only in the South are gradually coming into view in the Northern Hemisphere.
Scientists will be looking for the North Polar "Hexagon" that was seen by Voyager.
The Hexagon was a jet stream, deflected by a storm into a six-lobed pattern, that circled the Planet at 76° North Latitude.
This picture shows extensive storm activity and gives scientists hope that the Hexagon is still there. The shadows of the Rings of Saturn cut across the lower part of the image.
The image was taken in polarized infrared light with the Cassini spacecraft narrow-angle camera on Dec. 8, 2005, at a distance of app.x 3,2 MKM (about 2 MMs) from Saturn. The image scale is 37 Km (about 23 miles) per pixel".Gen 14, 2006

Saturn-PIA07672.jpgSaturn's limb (enhanced - and yet natural - colors)59 visiteOriginal caption:"Twice as far from the Sun as Jupiter, Saturn's colder temperatures mean that clouds form lower in its atmosphere. As a result, the visible cloud patterns - so striking on Jupiter - occur deeper inside Saturn, reducing their visibility in natural color views.
This enhanced-color view uses exaggerated contrast and intensity in order to make Saturn's cloud bands easy to see.
The Latitude seen at the image center is approximately 60° South of the Equator.
Images taken in blue (BL2), green and red (CB1) polarized spectral filters were combined to create this enhanced-color view. The images were taken with the Cassini spacecraft narrow-angle camera on Dec. 7, 2005, at a distance of approximately 3,1 MKM (1,9 MMs) from Saturn. The image scale is about 36 Km (app.x 22 miles) per pixel".Gen 12, 2006
