Fast forward to our modern age of space exploration, and scientists have gotten much better looks at Saturn and its rings. Voyager 1 and Voyager 2 opened our eyes to Saturn's unique rings when they flew past the planet in 1980 and 1981. Those images began to reveal some of the rings' ...
Saturn's rings might not be younger than the dinosaurs as recently suggested, but nearly as old as the giant planet itself at billions of years in age, a new study says. The age of Saturn's rings has long been controversial. Some researchers had thought the iconic features formed along ...
Knowledge of the incoming mass flux of these pollutants allows estimation of the rings' exposure time, providing a limit on their age. Here we report the final measurements by Cassini's Cosmic Dust Analyzer of the micrometeoroid flux into the Saturnian system. Several populations are present, ...
Saturn - Rings, Moons, Core: Saturn’s low mean density is direct evidence that its bulk composition is mostly hydrogen. Under the conditions found within the planet, hydrogen behaves as a liquid rather than a gas at pressures above about one kilobar, co
The planet hosts seven rings composed of boulder-size ice chunks. Durisen and research partner Paul Estrada took data from NASA's Cassini spacecraft, which orbited the planet for 13 years, to estimate the age of Saturn's rings — and their lifetime. ...
“pollution” coming from micrometeoroids, such as asteroid fragments smaller than a grain of sand. These constantly collide with the ring particles and contribute debris to the material circling the planet. The rings’ age has been hard to pin down, because scientists hadn’t yet quantified ...

The findings are based on data collected by NASA’s Cassini spacecraft while repeatedly diving between Saturn and its rings in 2017, shortly before its demise. By estimating the mass of the rings through gravity measurements, the researchers gauged the age of the three main rings: A, B ...
通读全文,尤其是第一段的“Saturn (土星) is famous for its lovely rings, but a new study suggests the planet has spent most of its 4.5 billion years without them. That’s because the rings are likely only 10 million to 100million years old, according to a newly published report in the ...
On the midsized saturnian satellites the largest craters may or may not have rings, but in general their central floors appear more complex than a simple central peak, so we use the lunar terminology (“basins”) for these magnificent structures....
