Making the paper: Carl Murray.

The article presents the study regarding Saturn's outermost ring, the F ring, conducted by Carl Murray and colleagues at Queen Mary, University of London in London, England. According to the author, Murray found out that constant collisions and the gravitational pull among a population of small satellites give the ring its form. It reveals that the narrow F ring of Saturn was discovered from images captured by the Pioneer 11 spacecraft in 1979. In addition, later data from Voyager 1 and 2 depicted that the ring as having a core about 1 kilometre wide surrounded by a 50 kilometre wide envelope, both supposedly held in place by the gravitational pull of Prometheus and Pandora, Saturn's shepherding moons.
