The photos Cassini has been sending back go beyond science. They are art.
In this image, Titan can be seen behind Saturn’s rings with Enceladus peaking onto the crescent. The bright surrounding ring is atmospheric haze above Titan, gas that is scattering sunlight to a camera operating onboard the robotic Cassini spacecraft. Since the image was taken pointing nearly at the Sun, the surfaces of Titan and Enceladus appear in silhouette, and the rings of Saturn appear similar to a photographic negative.
