The Brightest Region of Titan: Shikoku Facula

Caption NASA originale:"This image of Saturn's moon Titan from the Synthetic Aperture Radar Instrument on the Cassini spacecraft shows Shikoku Facula, a Region that is bright in both radar and visible wavelengths. This radar image was taken on April 30, 2006.
A circular feature with a radar-dark interior, probably an impact crater, is seen near the top of the image and is about 35 Km (about 22 miles) in diameter.
Numerous linear dark features are seen running across the image, mostly on the right-hand side. These features were seen on other radar images and interpreted as dune fields. Bright, ridge-like features mainly on the lower half of the image may be topographically "High Regions" (qualcosa di simile alle HighLands della Scozia). Radar-dark, thin, sinuous features, which may be channels draining from the bright to the dark Regions, are seen below the circular feature".
