HTTP:: Saturn Ring Formation Still Unexplained
--------
Ever since the 17th century, when Italian astronomer Galileo Galilei discovered that Saturn had rings around it, astronomers and astrophysicists have been trying to come up with a plausible explanation for how they were formed and why. To this day, the answer has eluded them, and each new scientific find about the planet, made with space telescopes or with the Cassini-Huygens space probe, only goes on to further deepen the mystery. Modern scientific means have allowed researchers to determine the fact that the multiple rings around the planet are made up of vast amounts of dust, ice and small rock fragments. Though they are only a few tens of feet in thickness, they are extremely widespread, and contain some 35 trillion-trillion tons of material inside them. They also possess the remarkable ability of regenerating themselves, if, for example, a space rock passes through. After the initial shock, the material mysteriously pulls itself together again, Space reports. Thank!
s to readings collected by Cassini and its Voyaged predecessors, it has now become obvious that the rings are in a process of constant evolution. Ring arcs have been photographed as forming in some instances, while one of the planet's many moons has been identified as emitting plumes of ice and dust, which contribute to the formation of new ri...
