‘Saturn and Rhea’ 2006 Science Photo Library Print by Science Photo Library Archive

Saturn’s second largest moon Rhea seen through the planet’s rings. The rings consist of particles of nearly pure water ice and meteoric dust and span almost 300,000 kilometres. The Cassini-Huygens spacecraft was launched in 1997 to investigate Saturn, its rings and its moons. This image was taken by Cassini’s narrow-angle camera on the 1st July 2006 at a distance of 1.2 million kilometres from Rhea. (Photo by Science Photo Library)
