A quintet of Saturn's moons come together in the Cassini spacecraft's field of view for this portrait. Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the image.
This image from NASA's Cassini spacecraft shows three moons -- Titan, Mimas, and Rhea. Titan, the largest moon shown here, appear fuzzy because we only see its cloud layers. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 25, 2015.
This view from NASA's Cassini spacecraft features a blue planet, Uranus, imaged by Cassini for the first time. Uranus is a pale blue in this natural color image because its visible atmosphere contains methane gas and few aerosols or clouds. - Image credit: NASA/JPL-Caltech/Space Science Institute
