The huge moon Titan is seen here as it orbits Saturn. Below Titan are the shadows cast by Saturn's rings. This natural color view was created by combining six images captured by NASA's Cassini spacecraft on May 6, 2012. [Credit: NASA/JPL-Caltech/Space Science Institute]

Note that we can't see any surface markings on Titan. This is because the surface is hidden by Titan's thick atmosphere.
