Saturn’s shepherd moon Daphnis makes waves
http://spaceflightnow.com/2017/01/19/saturns-shepherd-moon-daphnis-makes-waves/NASA’s Cassini spacecraft has captured the first close-up view of Daphnis, one of at least 62 moons found orbiting Saturn, plowing a path through the planet’s icy rings and raising waves in its wake.
The image taken by Cassini’s narrow-angle camera Jan. 16 is the best view ever taken of Daphnis, a football-shaped object carving a gap in one of Saturn’s outer rings. The spacecraft was about 17,000 miles (28,000 kilometers) from Daphnis at the time.
