Nightflight over Saturn

Caption NASA originale:"Saturn's atmosphere produces beautiful and sometimes perplexing features. Is the bright feature below center a rare crossing of a feature from a zone to a belt, or is it an illusion created by different cloud layers at different levels? The answer is not always easy to determine.
The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 938 nanometers.

The image was acquired with the Cassini spacecraft narrow-angle camera on May 12, 2006 at a distance of approx. 2,9 MKM (about 1,8 MMs) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 145°. Image scale is roughly 17 Km (about 10 miles) per pixel".
