Huge Collision May Have Formed Saturn's Rings And Inner MoonsSan Antonio TX (SPX) Dec 13, 2010 Simulations performed at Southwest Research Institute may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a paper published in Nature magazine's Advance Online Publication. Saturn's rings are at present 90 to 95 percent water ice. Because dust and debris from rocky meteoroids have polluted the rings, the rings are believed to have consisted of pure ice when they formed. This composition is unusual ... read more |
