Saturn silhouetted. Cassini spacecraft image of Saturn and its ring system with the Sun directly behind. The view revealed two previously unknown rings. One, associated with the orbits of the moons Janus and Epimetheus, lies in between the outer edge of the bright main rings and the thin grey/brown G Ring. The other, associated with the orbit of the moon Pallene, lies just inside the broad and diffuse outer E ring. Earth is seen as a bright dot at the ten o'clock position between the bright main rings and the G Ring. This is a composite of 165 images taken at infrared, visible light and ultraviolet wavelengths by the Cassini spacecraft on 15th September 2006, while it was around 2.2 million kilometres from Saturn.
