The Cassini spacecraft has just begun its 4-year tour around Saturn, but the mission is already proving a tour de force.

Size estimates suggest that the orbs are the smallest ever found around Saturn, researchers reported this week. Earlier this month, other scientists described short-lived storms in Saturn's atmosphere.
