PIA01990: Neptune - Dark Oval

Neptune - Dark Oval


The large, dark oval spot in Neptune's atmosphere is just coming into view in this picture returned from the Voyager 2 spacecraft on June 30, 1989. The spacecraft was about 83 million kilometers (51.5 million miles) from Neptune. Voyager scientists are interested in the dark oval cloud system, a very large system similar to Jupiter's Great Red Spot. Contrast of the features in Neptune's atmosphere is similar to that obtained at Saturn at about this same distance and lighting, whereas the features are similar to those seen at Jupiter.
