What are the rings of Jupiter composed of.

Jupiter's rings are made up of fine dust particles (average size a few microns (that's tiny!), in contrast to Saturn's rings, which are made up of mostly pebble-to-boulder size objects). And unlike Saturn's rings (which are composed primarily of ice), Jupiter's rings are made of rocky material (in powdered form). It appears that this ring material escapes after some time and so must be continually replenished, possibly from meteor bombardment of some of Jupiter's moons or perhaps from material ejected by volcanoes on Jupiter's moon Io.
