Even in a pacific looking stage such as this one of Saturn and a moon Tethys, a Cassini booster reveals clues about how Saturn is ever-changing. Saturn’s northern hemisphere still shows a scars of a outrageous charge that raged by most of 2011 (see PIA14905). And, day by day, a shadows expel by a rings on a planet’s southern hemisphere are flourishing wider as a seasons swell toward northern summer. See PIA11667 and PIA09793 to learn about a changing seasons and a shadows expel by a rings.
Tethys (660 miles, or 1,062 kilometers across) appears above a rings to a left of a core of a image.
The picture was taken with a Cassini booster wide-angle camera on Jan. 10, 2012 regulating a bright filter supportive to wavelengths of near-infrared light centered during 752 nanometers. The perspective was performed during a stretch of approximately 1.4 million miles (2.3 million kilometers) from Saturn and during a Sun-Saturn-spacecraft, or phase, angle of 39 degrees. Image scale on Saturn is 84 miles (136 kilometers) per pixel.
