The Cassini-Solstice mission Discovered that there might be more rings around Saturn than can be seen with telescopes.

“It seems almost incredible that such a ring of cosmic dust should be able to exist for ever, so to speak, without other governing forces than gravitation…”

— Kristian Birkeland 1913

Scientists from the Max Planck Institute found what might be partial rings surrounding the giant gas planet in a nearly invisible collection of small arc segments. Using Cassini’s onboard magnetospheric sensors, the research team found that there are two areas near Saturn where highly energetic electrons suddenly drop out – presumably because something is absorbing them.

In March 2008, the Cassini team reported a similar discovery using the same instrument, except then it was to announce a ring structure orbiting the moon Rhea...............
