Saturn's Rings
It’s your periodic Cassini Appreciation Post (no, Cassi, it’s not about you!).
From Jason Major: “Here's a view of Saturn's rings made from images captured with Cassini on July 4, 2008. Prometheus is visible inside the F ring at the bottom; the even smaller Atlas is on the left along the outer edge of the A ring. Saturn's shadow falls across the rings at upper right.”
