    When I was a kid, the astronomy books I gawked at all said Jupiter's red spot was as far across as four Earth-diameters.

    In recent years, every source I've looked at said three Earth-diameters, and astronomers have been talking about how its shrinking.

    It is just a storm, after all- an atmospheric anomaly that isn't infinite. We don't really know when it started, but we've had it under observation since basically the time of Galileo, and it appears the show will be over in the next generation or two.

    Most people don't know it, but the same is true of Saturn's rings. They aren't going to last forever. The timescale on that one, however, is long enough that we don't have to worry about it. ;)

    In the case of rings though it is fairly easy to create a new set. Just push a small moon to within the limit where it will be shredded by Saturn's gravity.
