Saturn’s rings may be no more than 400 million years old

Saturn’s rings might have formed while trilobites scuttled about on Earth. Space dust has been accumulating on the icy halos for no more than 400 million years, researchers report in the May 12 Science Advances. The rings of Saturn are made of countless icy particles, which become covered with dust as tiny meteoroids strike them. These dustings darken the rings’ complexion like mud sullies snow on roads in winter.
