The red arcs are narrow, curved lines on the moon's surface, and are among the most unusual color features on Saturn's moons to be revealed by Cassini's cameras. Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the enhanced-color views, which highligh ... read more
