The shadow of Saturn’s globe on the rings, which stretched across all of the rings earlier in the Cassini spacecraft’s mission, now barely makes it past the Cassini Division. The changing length of the globe’s shadow marks the passing of the seasons on Saturn. As the planet nears its northern-hemisphere solstice in May 2017, the shadow will get even shorter.
