Saturn's Supersized Ring
|
| Topic: Saturn system |
10/09/09 |
| Astronomers have discovered an enormous ring around Saturn that may be linked to the moon, Phoebe. The finding highlights connections between the moons and rings of Saturn. The research could help in determining how the Saturn system was formed and, ultimately, the habitability of moons orbiting the giant planet. |

Mysterious Enceladus
|
| Topic: Saturn system |
09/04/05 |
| Evidence is mounting that the atmosphere of Enceladus, first detected by the Cassini Magnetometer instrument, is the result of venting from ground fractures close to the moon's south pole. New findings from the close flyby of Enceladus by Cassini this past July add to the emerging picture of a small icy body, unusual in its past and present level of activity. |

Prometheus Steals Ring
|
| Topic: Saturn system |
12/04/04 |
| The tiny moon, Prometheus, shapes Saturn's outer ring by shepherding icy debris into ridges and gaps as Prometheus orbits the giant planet. The Cassini spacecraft captured images not only showing its gravitational interplay, but also its debris trail in a haunting show of how the rings change today. |

| The interplay of light and gravity feature in the shaping of Saturn's rings. As its moon orbit, they attract dust particles into fine bands or divisions. New images from the Cassini probe reveal both what the moons look like up close and also how they sculpt the planet's signature rings. |

Saturn Sightings: Tethys
|
| Topic: Saturn system |
10/08/04 |
| The Cassini spacecraft in orbit around Saturn caught a glimpse of Tethys, a cratered, icy moon. Notable for Tethys are its split fissure and enormous crater, both of which leave the impression that its fragile surface is remaking itself slowly. |
