Photographers around the world looked up to the sky this past weekend to capture the "supermoon." This is the phenomenon when the moon makes its closest approach to Earth, appearing 30 percent brighter and about 14 percent larger than a typical full moon. It occurs about once every 14 months and is technically called a perigee full moon. At 221,823 miles from Earth, the supermoon was a feast for the eyes.-Leanne Burden Seidel (24 photos total)

This is an image of Saturn showing its rings and the shadows of the rings below, but also of Titan and Prometheus. Saturn’s largest moon, Titan, looks small here, pictured to the right the giant Saturn in this Cassini spacecraft view. Can you find the moon Prometheus (only 53 miles across)? It appears as a tiny white speck above the rings in the far upper right of the image.

The dozens of icy moons orbiting Saturn vary drastically in shape, size, surface age and origin. Some of these worlds have hard, rough surfaces, while others are porous bodies coated in a fine blanket of icy particles. Some, like Dione and Tethys, show evidence of tectonic activity, where forces from within ripped apart their surfaces. Some appear to have formed billions of years ago, while others, like Janus and Epimetheus, might have originally been part of larger bodies. The study and comparison of these moons tells scientists about the history of the Saturn System and the solar system. The image was taken with the Cassini spacecraft wide-angle camera on Jan. 5, 2012.
