Neptune is almost Uranus's twin in size and appearance. Somewhat bluer, its atmosphere seems to be more active, with whitish storm clouds and an occasional Dark Spot, as first imaged by Voyager 2 in 1989 (Hardy was at JPL when the pictures from the fly-by came in). This is probably a giant hurricane that has been raging for over 400 years.
