Saturn Propellers Reflect Solar System Origins
|
| Topic: Saturn system |
07/11/10 |
| Scientists have identified a new class of moons in the rings of Saturn. It is the first time that scientists have been able to track the orbits of individual objects in a debris disk. The research is revealing clues about disks around other stars in our universe that are too far away to observe directly. |

| Topic: Saturn system |
03/31/10 |
| NASA's Cassini spacecraft has captured a temperature map of Saturn's icy moon Mimas that shows unexpected hot regions. Studying moons like Mimas can improve knowledge of the Saturn system's environment, and could help astrobiologists determine if habitats for life might exist on moons around giant planets. |

Investigating Iapetus
|
| Topic: Saturn system |
12/12/09 |
| Two new studies have shed some light on a centuries-old mystery surrounding Saturn's moon Iapetus. The studies also provide new information about the Saturn system and how the moons and rings of the giant planet interact. This is important in determining the potential for habitable environments on moons around giant planets. |

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. |
