International scientists have found a tiny new moon hidden in one of Saturn's outer rings.
It was first captured by cameras on board the Cassini spacecraft last August, and has since been seen on multiple occasions.
The moon is about one-third of a mile (a half-kilometer) across and circles Saturn as a part of the planet's sixth, or G, ring. "Before Cassini, the G ring was the only dusty ring that was not clearly associated with a known moon, which made it odd," said Matthew Hedman, a Cassini imaging team associate at Cornell University in Ithaca, New York. "The discovery of this moonlet, together with other Cassini data, should help us make sense of this previously mysterious ring."
