Neptune as seen from the Voyager-2 flyby in 1989. Visible are the Great Dark Spot and various fast moving white clouds in the upper atmosphere.
Neptune's odd "Cantelope Terrain" and plains composed of likely nitrogen and methane ices.
Plumes of material outgassing from beneath the surface of Triton indicate the flow of the moon's thin atmosphere.
An artist illustration of what one of Triton's nitrogen geysers might look like from ground level.
Photographs of Neptune showing the atmospheric changes in the planet's rotation.
Dark material is seen steaming from beneath Neptune's surface in this view of strange geyser-like formations. The flow of the thin atmosphere can be seen in the directions of the streaks.
