The Rings-PIA08257.jpgThe Music of Pan...The Waves in the Rings...55 visiteCaption NASA:"The Encke Gap displays gentle waves in its inner and outer edges that are caused by gravitational tugs from the small moon Pan. These scalloped edges were captured in a dramatic image taken by Cassini during its insertion into Saturn orbit in 2004.
The Encke Gap is a 325-Km (about 200-mile) wide division in Saturn's outer A-Ring.
Pan (26 Km, or approx. 16 miles across) orbits squarely in the center of this gap.
The original image was stretched in the horizontal direction by a factor of four to exaggerate the amplitude of the waves, then reduced to half size and cropped to focus on the gap.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 23, 2006 at a distance of approx. 290.000 Km(such as about 180.000 miles) from Saturn.
Scale in the original image was roughly 1 Km (about 0,6 mile) per pixel".

OPP-SOL929-1N210665715EFF75__P0685R0M1.jpg"Little One": just before Victoria (1) - Sol 92955 visiteUno splendido (e piccolo) cratere - dalle dimensioni apparenti di 25/30 mt di diametro - che abbiamo battezzato "Little One": l'ultima fermata prima del grande Victoria Crater il cui bordo (rim) lo si può già vedere con una discreta chiarezza (nei tre frames precedenti).
La NASA, a proposito di nomi e battesimi, ha invece chiamato questo piccolo cratere con il nome di "Emma Dean".

The Rings-PIA08259.jpgGravitational Disturbances55 visiteCaption NASA originale:"The clumpy disturbed appearance of the brilliant F-Ring constantly changes. The irregular structure of the Ring is due, in large part, to the gravitational perturbations on the ring material by one of Saturn's moons, Prometheus (about 102 Km, or 63 miles across).
Interior to the F-Ring, the A-Ring bears a striking resemblance to a classic grooved, vinyl record. Visible here are the Keeler Gap (about 42 Km, or 26 miles wide) and the Encke Gap (about 325 Km, or 200 miles wide).
The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 862 nnmts. The view was acquired with the Cassini spacecraft narrow-angle camera on July 26, 2006 at a distance of approx. 1,5 MKM (about 900.000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 141°. Image scale is roughly 8 Km (such as about 5 miles) per pixel".
