Great Red Spot Shrinking

Jupiter's Great Red Spot, a storm larger than Earth itself, may be winding down.  It could disappear entirely within fifteen years, scientists say.

Or not.  Astronomers have been observing the Spot essentially ever since they've had telescopes, nearly 400 years.  During that span, the Spot has nearly disappeared on occasion, but it has always come back strong.  We'll see about this time.
