Saturn's shimmering rings may be as old as the solar system, scientists said Wednesday, debunking earlier theories that the rings were formed during the dinosaur age. picked by AutumnLotus 9 months ago tags saturn rings older |

Saturn: jewel of the solar system, taker of breaths, ringed beauty. Even veteran astronomers can't help but gasp when they see her through a small telescope. 1 comments edit related share scienceRed Alert: Saturn's rings are vanishing. Around the world, amateur astronomers have noticed the change; Saturn's wide open rings are rapidly narrowing into a thin line. picked by AutumnLotus 6 months ago |
The discovery of more oddly shaped gaps in Saturn's rings strengthens the case that one of the planet's moons was smashed to bits in an ancient collision. Shaped like airplane propellers, the gaps likely formed when "moonlets" as large as football stadiums plowed through Saturn's ring particles while orbiting the planet. picked by AutumnLotus 11 months ago 6 comments edit related share plime.com |
New observations by a spacecraft suggest Saturn's second-largest moon may be surrounded by rings. If confirmed, it would the first time a ring system has been found around a moon. picked by AutumnLotus 6 months ago 0 comments edit related share science |
Gaps in the soup of high-energy particles near the orbits of two of Saturn’s tiny moons indicate that Saturn may be surrounded by undiscovered, near-invisible partial rings. A paper in the February issue of the journal Icarus suggests that the larger saturnian moons may not be the only ones contributing material to Saturn's ring system. picked by AutumnLotus 7 months ago 1 comments edit related share science |

The formation of strange flying-saucer-shaped moons embedded in Saturn's rings have baffled scientists. New findings suggest they're born largely from clumps of icy particles in the rings themselves, an insight that could shed light on how Earth and other planets coalesced from the disk of matter that once surrounded our newborn sun. picked by AutumnLotus 9 months ago 0 comments edit related share plime.com |

Cassini scientists may have identified the source of one of Saturn's more mysterious rings. Saturn's G ring likely is produced by relatively large, icy particles that reside within a bright arc on the ring's inner edge. picked by AutumnLotus 1 year ago 0 comments edit related share plime.com |
Saturn has a newly discovered ring, a faint trail of particles just visible in between some of its better-known rings, NASA said on Tuesday. picked by Galoot 2 years ago 1 comments edit related share science |
One of Saturn's rings does housecleaning, soaking up material gushing from the fountains on Saturn's tiny ice moon Enceladus, according to new observations from the Cassini spacecraft. picked by AutumnLotus 7 months ago 1 comments edit related share science |
Scientists appear to have solved a long-standing mystery about the cause of anomalies in Jupiter's gossamer rings. In a new study published, they report that a faint extension of the outermost ring beyond the orbit of Jupiter's moon Thebe, and other observed deviations from an accepted model of ring formation, result from the interplay of shadow and sunlight on dust particles that make up the ring... read full post picked by AutumnLotus 4 months ago 0 comments edit related share science |
Saturn is now at its best in our late-winter sky. It appears below and to the left of the conspicuous "sickle" or backwards question-mark pattern of stars marking the head and mane of the constellation of Leo, the Lion. 1 comments edit related share scienceWhat we see with the naked eye is a bright yellowish-white "star" shining with a steady light. picked by AutumnLotus 7 months ago |

The director of a stage musical based on "Lord of the Rings" visited J.R.R. Tolkien's grave to get his approval, and to apologize if the author didn't like the idea. Apparently, he didn't take the sound of something spinning six feet below him as a clue. picked by Wingnut 2 years ago 3 comments edit related share entertainment |

In the 1980s, NASA's Voyager spacecraft measured regular pulses of radio waves coming from Saturn every 10 hours and 39 minutes. That was close to the rough rotation rate scientists have obtained by tracking the motion of Saturn's clouds, suggesting the pulse period is tied to the planet's rotation rate. !!Sound and Video links!! picked by drnothing 10 months ago 3 comments edit related share plime.com |
