NASA’s Cassini spacecraft gets up close and personal with Saturn’s rings

You can clearly see ridges on the left of the photo, which are called density waves. The waves were created by Prometheus, one of Saturn’s moons, as it moves in its orbit around the planet.

This close-up photo of the A ring was taken at a distance of 33,000 miles away with Cassini’s wide-angle camera.

Cassini is in the last phase of its Saturn mission, which is scheduled to end in April when the probe is expected to dive into the planet’s atmosphere in its final farewell.
