Odd 'Y' Shape Dominates Saturn Moon Enceladus (Photo)

The giant, sinuous "Y," which appears at the boundary between sunlight and darkness in the photo, is a tectonic feature related to stresses in the icy shell of Enceladus, NASA officials said. Cassini took the newly released image on Feb. 15, 2016, at a distance of about 60,000 miles (100,000 km) from Enceladus.
