New Ring of Saturn

WASHINGTON (Reuters) - Saturn has a newly discovered ring, a faint trail of particles just visible in between some of its better-known rings,
NASA said on Tuesday. The orbiting Cassini spacecraft caught sight of the ring and other rare features when the sun passed directly behind Saturn in what is known as an occultation, providing bright backlight to the rings.
Cameras aboard Cassini also caught images of wispy fingers of icy material stretching out tens of thousands of kilometers (miles) from Enceladus, another confirmation that the moon is spraying material that may be making up Saturn's outer E-ring.
Saturn has at least 47 known moons and at least seven rings. The joint U.S.-European Space Agency Cassini mission, launched in 1997, is spending four years examining Saturn.
The new ring can be barely seen outside the brighter main rings of Saturn and inside the G and E rings. It coincides with the orbits of Saturn's moons Janus and Epimetheus, and NASA researchers said that meteoroid impacts on those moons may have kicked off particles that coalesced into the ring.
