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 tags high energy electron holes rings particles |

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 |
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 |

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 |

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 |
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 1 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 |
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 |

Imagine a place awash with more hydrocarbons than a Texan oilman can dream of and where no one has staked a single claim -- all that energy is just going begging. The problem: this massive reserve is at least 1.2 billion kilometers (750 million miles) away from Earth, on a tiny inhospitable world where on a warm day it's minus 179 degrees Celsius (minus 290 degrees Fahrenheit). picked by AutumnLotus 7 months ago 5 comments edit related share science |

Colossal impacts in the outer reaches of the solar system may have bowled over remote, frozen moons, leading to vast cracks across their surfaces. The many impact craters that have pocked our moon and Earth reveal our solar system can be like a shooting gallery, with asteroids and comets regularly striking planets and their companions. These monumental blows can literally set moons rocking. picked by AutumnLotus 10 months ago 0 comments edit related share plime.com |
