New photos from the Cassini space-craft have returned these amazing photos of Saturn’s rings.
“What’s that jaggedy dark stuff behind the brightest ringlet in the image? We’re only a few months away from Saturn’s equinox, the day when the Sun will pass through the plane of Saturn’s rings. So to an observer standing on Saturn’s rings, the Sun is beginning to set, and casting long shadows. We’re seeing shadows cast from structure within Saturn’s rings. COOOOOOOL.”
