Cassini makes detailed ring map
By Dr David Whitehouse
Science editor, BBC News website

A simulated colour image maps the differences in particle size and density

The Cassini probe has obtained the most detailed view yet of Saturn's ring system, making clear even a ring that had eluded previous space missions.

By passing radio waves through the rings, the spacecraft was able to measure the size of the ice and rock fragments from which they are made.

The denser the material in the rings, the weaker the radio signal received from Cassini back on Earth.

The joint US-European mission has been in orbit around Saturn since last July.
