To the surprise of Cassini imaging scientists, the wispy terrain does not consist of thick ice deposits, but rather the bright ice cliffs created by tectonic fractures.

Dione possesses numerous features with names from Virgil's "Aeneid." The prominent crater showing a central peak below the center is Dido, a 118-kilometer-wide (73-mile) crater named after the supposed founder of Carthage. The crater just above Dido is Antenor, an 82-kilometer-wide (51-mile) impact crater named after the nephew of Priam who founded the Italian city of Padua. At the upper right is the 97-kilometer-wide (60-mile) impact crater Turnus, which lies at the western end of Carthage Linea, a region of bright, fractured terrain. Dione is 1,118 kilometers (695 miles) across.</p><p>The sunlit terrain seen here shows some of the wispy markings on the moon's trailing hemisphere.
