What's that weird thing around Saturn's second-largest moon? (Rhea)

There is something around the moon of Rhea. It's not a ring, and it sure is weird, say researchers.

Back in 2005, a suite of six instruments on the Cassini spacecraft detected what was thought to be an extensive debris disk around Saturn's moon Rhea, and while there was no visible evidence, researchers thought that perhaps there was a diffuse ring around the moon. This would have been the first ring ever found around a moon. New observations, however, have nixed the idea of a ring, but there's still something around Rhea that is causing a strange, symmetrical structure in the charged-particle environment around Saturn's second-largest moon.

Iapetus also has some weirdness, too!

Looks like Danny DeVito, Rhea's husband.

Klingons, of course.

I left my spaceship parked in orbit around Rhea. Is there a problem? Am i getting a ticket?

[piytar]

Cloaking field of the V invasion force, of course.

Berries of some kind?

[ASOC]

Or some kind of field caused by magnetohydrodynamic generation (caused by tidal forces) from the metal interior of the moon.

That or the "moon" is an old interstellar spaceship from the First (Human?) Empire.

What will happen when it is finally fully awake?
