A: Scientists discovered that Saturn's magnetosphere near Rhea did not have energetic electrons when they used the Cassini orbiter in November 2005.
Q: What does it mean to say that there are "denser rings or arcs" around Rhea?
A: It means that there are areas with a higher concentration of solid material, such as particles many decimeters to about a meter in diameter, forming rings or arcs around Rhea.
Q: What type of particles make up these denser rings and arcs?
A: These denser rings and arcs are made up of solid particles many decimeters to about a meter in diameter.
Q: How would this be different from other known rings seen around moons?
A: This would be different from other known rings seen around moons because it would be the first time a thin ring system has been seen around a moon.
