Cassini offers best-ever view of Saturn’s rings


A sequence of images captured by NASA’s Cassini spacecraft last month are the most detailed pictures ever taken of Saturn’s famous rings, revealing complex, unexplained bands and the movements of dozens of tiny icy moonlets spinning around the planet.

In its final year of operation, Cassini is now in a “ring-grazing” orbit around the gas giant, zipping just outside Saturn’s outer F ring at an average distance of 57,000 miles (91,000 kilometers) from its cloud tops, and yielding the mission’s best views of the bands of icy particles encircling the planet.
