Now you're lost in a haze of alcohol soft middle age
The pie in the sky turned out to be miles too high...
And you hide, hide, hide,
Behind brown and mild eyes..."

Japetus-SquaredTerrain.jpgSquares on Japetus?57 visiteUno splendido, inquietante ed...illusorio profilo individuato dal sempre bravissimo Marco Faccin. Strutture squadrate su Giapeto? Evidenze di "artificialità"?...
Ovviamente no: questo frame (e relativo detail mgnf) rappresentano solo un modo per vedere - e per far vedere! - come, volendo, si possono trovare "strutture regolari" su altri Corpi Celesti.
Illusioni determinate dalla distanza, dall'angolo di ripresa, dalla qualità del frame e dalla voglia di vedere "segni tangibili di intelligenza (passata o presente) altrove": trovare queste strutture (che appartengono alla Classe delle Strutture "Effimere") è un gioco; evidenziarle è una curiosità; spiegarle per quello che sono (senza costruirci sopra delle eso-archeo-baggianate) è, secondo noi, un dovere.
Un grazie di cuore (ed un grande BRAVO!) al Dr Faccin per aver individuato un dettaglio (comunque) intrigante e per lo spunto di riflessione che, con esso, ci ha voluto dare.MareKromium

Saturn-PIA08393.jpgThe "Opposition Effect" (again)57 visiteThe Opposition Effect, a brightness surge that is visible on Saturn's Rings when the Sun is directly behind the Spacecraft, is captured here as a colorful halo of light moving across Saturn's Sunlit Rings. The rainbow of color seen here is actually an artifact and a by-product of the spot's movement and the way the color image was produced. Cassini acquires color images by taking sequential exposures using red, green and blue spectral filters, which are then composited together to form a color view. The bright patch traveled across the Rings between exposures taken for this view, creating a series of 3 colorful spots showing its position at 3 separate moments.
This view looks toward the Sunlit side of the Rings from about 9° below the Ring-Plane.
The images in this view were acquired with the Cassini spacecraft wide-angle camera on June 12, 2007, at a distance of approx. 523.000 Km (such as about 325.000 miles) from Saturn.
Image scale is roughly 31 Km (about 19 miles) per pixel.

Saturn-PIA08388.jpgLooking at the Giant57 visiteSaturn sits nested in its rings of ice as Cassini once again plunges toward the graceful giant. This natural color mosaic was acquired by the Cassini spacecraft as it soared 39° above the unilluminated side of the Rings.
Little light makes its way through the Rings to be scattered in Cassini's direction in this viewing geometry, making the Rings appear somewhat dark compared to the reflective Planet. The view can be contrasted with earlier mosaics designed to showcase the Rings rather than the Planet, which were therefore given longer exposure times.
Bright clouds play in the blue-gray skies of the North. The Ring shadows continue to caress the Planet as they slide farther South toward their momentary disappearance during Equinox in 2009.
The Rings' reflected light illuminates the Southern Hemisphere on Saturn's night side.
The scene is reminiscent of the parting glance of NASA's Voyager 1 as it said goodbye to Saturn in 1981 (see PIA00335). Cassini, however, will continue to orbit Saturn for many years to come.
Three of Saturn's moons are visible in this image: Mimas (about 397 Km across) at the 2 o'clock position, Janus (about 181 Km across) at the 4 o'clock position and Pandora (about 84 Km across) at the 8 o'clock position. Pandora is a faint speck just outside the narrow F-Ring.
This mosaic was constructed from wide-angle camera images taken just before the narrow-angle camera mosaic PIA08389.
The view combines 45 images -- 15 separate sets of red, green and blue images -- taken over the course of about two hours, as Cassini scanned across the entire Main Ring System.
The images in this view were obtained on May 9, 2007, at a distance of approx. 1,1 MKM (about 700.000 miles) from Saturn.
Image scale is about 62 Km (approx. 39 miles) per pixel. MareKromium

Titan_and_Saturn-PIA08398.jpgIn-Transit...57 visiteThe murky orange disk of Saturn's moon Titan glides past -- a silent, floating sphere transiting Saturn.
Titan's photochemical smog completely obscures the surface in such natural color views. Its high-altitude hazes are visible against the disk of Saturn as they attenuate the light reflected by the Planet.
This view was acquired from less than 1° above Saturn's Ring-Plane.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini spacecraft narrow-angle camera on Aug. 1, 2007, at a distance of approx. 2,4 MKM (such as about 1,5 MMs) from Titan. Image scale is roughly 15 Km (about 9 miles) per pixel.MareKromium
