  In addition to its suite of narrow dense rings, Uranus is surrounded by an
extremely complex system of dusty rings that were most clearly seen by the
Voyager spacecraft after it flew past the planet. A new analysis of the highest
resolution images of these dusty rings reveals that a number of them are less
than 20 km wide. The extreme narrowness of these rings, along with the fact
that most of them do not appear to fall close to known satellite resonances,
should provide new insights into the forces responsible for sculpting the
Uranian ring system.
