New Ring Around Saturn

Posted by michael on from the radiation-may-be-hazardous-to-your-health dept.

The Fun Guy writes "From the New York Times: 'In its first month orbiting Saturn, the Cassini spacecraft has detected a new radiation belt in an unexpected place, its invisible swarm of trapped high-energy particles circling the planet inside the inner edge of Saturn's signature disk of luminous rings.' Cassini has also seen 'a striking glow emanating day and night from the planet's largest moon, Titan.' A moon that shines with unborrowed light!"

    It is entirely conceivable that ring can be used as a synonym for belt, particularly in this instance. Sure, radiation belts are typically called "belts" but there's no reason why they can't be called "rings".

    There's a very good reason one is call rings and one is called belts. Look at the picture. Sure it's possible to have a radiation ring and a rock/ice belt, but that doesn't change the fact that a radiation belt was found.
