Bright Splat on Rhea
This Cassini image of Saturn's moon Rhea shows a bright, white spot in its leading hemisphere. This bright feature could have come from a large impact, and has been examined by Cassini several times from different angles. Cassini took the photo on June 25, 2005 when it was approximately 1.1 million km (700,000 miles) away from the moon.
