With Explore the Planets, investigate the planets, their moons, and understand the processes that shape them. By G. Jeffrey Taylor, Ph.D. See our DVD collection.


Saturn, the sixth planet from the Sun, has the most spectacular set of rings in the solar system. We now know that Saturn has moons in addition to its complex ring system.

Have you ever seen the <a href="/earth/Magnetosphere/aurora.html">Southern or Northern Lights</a>? Earth isn't the only planet that puts on these beautiful light shows, which are also called the "<a href="/earth/Magnetosphere/aurora.html">aurora</a>". Aurora have been seen at both <a href="/saturn/saturn_polar_regions.html">poles of Saturn</a>, too, as well as at the poles of <a href="/jupiter/magnetosphere/jupiter_aurora.html">Jupiter</a>.  These "<a href="/earth/Magnetosphere/tour/tour_earth_magnetosphere_09.html">curtains of light</a>" sometimes rise 1,200 miles (2,000 km) above the <a href="/saturn/atmosphere/S_clouds_overview.html">cloud tops</a> near Saturn's poles. The <a href="/space_missions/HST.html">Hubble Space Telescope</a> took this picture in 2004.<p><small><em>Image courtesy of NASA, ESA, J. Clarke (Boston University), and Z.
