Nope, that’s not an error in the photograph. The ghostly white stripe in Saturn’s rings was captured by Cassini on July 23, 2006. This is the first time that Cassini has seen spokes in Saturn’s rings in nearly a year, and the first time from the sunlit side of the rings. Some scientists think the spokes might be caused by meteoroid impacts onto the rings. Others suggest they’re created by an instability in Saturn’s magnetic field.
