How old are the rings of Saturn? New study turns previous theory upside down
The rings of Saturn consist of ice crystals, dust grains and rock fragments and may be billions of years old, contrary to the previous assumption of 100-400 million years. A new study, published in the scientific journal Nature Geoscience, shows that micrometeoroid impacts at speeds of over 25 kilometers per second do not significantly pollute the rings, as the material escapes into the atmosphere or space as nanoparticles and ions, as planetary researcher Ryuki Hyodo from the research team in..

How old are the rings of Saturn? New study turns previous theory upside down
Saturn's rings are likely billions of years old, although previous studies dated them to 100 to 400 million years, while the planet Saturn itself is 4.5 billion years old. With small telescopes, the rings of ice crystals, dust grains, and rock fragments are well observable. Micrometeorite impacts at speeds over 25 km/s do not strongly contaminate the rings, as ice blocks and micrometeoroids evaporate and nanoparticles as well as atoms and molecules are formed, which escape into the atmosphere..

Rätsel um Saturn-Ringe gelöst? Neue Studie bringt bisherige Theorie ins Wanken
Eine neue Studie vom Institut für Wissenschaft in Tokio und dem Centre national de la recherche scientifique (CNRS) in Paris deutet darauf hin, dass die Saturn-Ringe möglicherweise viel älter sind als bisher angenommen. Bisherige Theorien gingen davon aus, dass die Ringe vor etwa 100 Millionen Jahren entstanden sind, während der Gasplanet Saturn selbst vor 4,5 Milliarden Jahren entstand. Die neue Studie zeigt jedoch, dass Meteoroiden-Bombardement die Ringe nicht so stark "verschmutzt", wie erw..
