NASA's probe Saturn Cassini has sent back spectacular views from the Solar System's second largest planet.

The above image shows the tiny cratered moon Janus passing in front of Saturn's famous rings. It's dwarfed by whopper of a moon Titan behind, with a thin cresent lit by the Sun. Titan is bigger than inner planet Mercury.

This snap was taken on Tuesday with Cassini's narrow-angle camera.

Cassini recently found evidence of water on another of Saturn's moons.®
