Saturn's Rings Disappearing: Scientists Alarmed.

Saturn's rings are falling in on the planet as icy rain due to its intense gravity, according to researchers. Dr. James O’Donoghue from the Japan Aerospace Exploration Agency will track the destruction of the rings using some of the world's most powerful telescopes. The rings are expected to be part of Saturn for only a few hundred million years, and their erosion rate is still being studied. The rings are thought to be pieces of comets, asteroids, or shattered moons that broke up before they reached the planet.
