Strange Phenomenon Orbiting Saturn
A mysterious clump of charged particles has been found orbiting Saturn. At the European Planetary Science Congress in Potsdam, astrophysicists from John Hopkins University presented this Cassini data. The donut of charged particles surrounding Saturn is bent out of shape. Some mysterious influence is affecting the ring current.
Planets with magnetic fields can trap charged particles to form electrified clouds. Earth's ring current appears during solar flares. As we saw months ago, the moon Enceladus keeps Saturn's vicinity supplied with charged particles. The ring current can bend Saturn's magnetic field.
The biggest mystery is a "clump" of charged particles. This phenomenon is between 485,000 and 1,000,000 kilometers from the surface. It orbits synchronously with the planet every 10 hours and 47 minutes. Astronomers are at a loss to explain its origin.
We can do some math here. A synchronous orbit with Saturn would be 529,000 km above the surface, right in the middle of the phenomenon. Extra particle velocity would push the clump into an oblong shape. Whatever the source of charged particles, it forms a natural synchronous satellite. This would be a good place to look for a Black Hole.
Update from Potsdam: Using our Keck II telescope atop Mauna Kea, astronomers have captured the first glare-free images of Uranus' rings. Their findings will appear in the August 24 issue of Nature. Data shows that the rings change. The innermost zeta ring has moved several thousand miles closer to Uranus than when it was first discovered. Though the narrow rings should require "shepherd moons" to keep them in place, few such moons have been seen. This might be another place to look for unseen objects. ESO Press Release
