What, are planets not supposed to change?
Change is the universal constant.
"New observations by the international Cassini spacecraft reveal that Saturn's trademark shimmering rings, which have dazzled astronomers since Galileo's time, have dramatically changed over just the past 25 years.
"Among the most surprising findings is that parts of Saturn's innermost ring, the D ring, have grown dimmer since the Voyager spacecraft flew by the planet in 1981, and a piece of the D ring has moved 125 miles inward toward Saturn.
"While scientists puzzle over what caused the changes, their observations could reveal something about the age and lifetime of the rings."
Additionally:
"Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere -- separate from that of the planet itself.
During its close fly-bys of the ring system, instruments on Cassini have been able to determine that the environment around the rings is like an atmosphere, composed principally of molecular oxygen.
