Atmospheric Features on Neptune

Caption

In this image, the colors and contrasts were modified to make the planet’s atmospheric features stand out. The winds in Neptune's atmosphere can reach the speed of sound or more. Neptune's Great Dark Spot stands out as the most prominent feature on the left. The fainter Dark Spot 2 and the South Polar Feature are locked to the planet's rotation, which allowed Karkoschka to precisely determine how long a day lasts on Neptune.
