Nasa has released spectacular images of Saturn’s rings, revealing that the rings may be home to millions of orbiting “moonlets”.

The images from the Cassini spacecraft resolve details on a scale of 550 metres – around the size of the tallest buildings on Earth. They include previously unseen features within the rings, including giant double-armed “propeller” structures that suggest a constellation of miniature moons are hidden within the planetary rings.
