Saturn-PIA10486.jpgTwo sides of Saturn's "Hexagon"56 visiteCaption NASA:"Saturn's North Polar Hexagon appears to be a long-lived feature of the Atmosphere, having been spotted in images of Saturn in the early 1980s, again in the 1990s, and then by the Cassini Spacecraft in the past several years.
The persistent nature of the Hexagon in imaging observations implies that it is present throughout Saturn's 29-year seasonal cycle. Two sides of the Hexagon are seen here.
This view was obtained from about 67° above the Equator. The image was taken with the Cassini Spacecraft wide-angle camera on Aug. 25, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. The view was acquired at a distance of approx. 566.000 Km (about 352.000 miles) from Saturn.
Image scale is roughly 31 Km (about 19 miles) per pixel".MareKromium
