Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it.

In 2018, a new Great Dark Spot was discovered on Neptune, nearly identical in size and shape as the one observed by Voyager 2 in 1989. The spot is in the northern hemisphere and is drifting westward …

By studying the properties of dark spots and how they form on Neptune, more can be learned regarding circulation patterns and energy transport below the clouds in this class of planet.

9, Voyager 2 tracked a large, oval-shaped, dark storm in Neptune’s southern hemi-sphere. This “Great Dark Spot” was large enough to contain the entire Earth,

Planet of Extremes Starting on 23 January 1989, twelve years after its launch, Voyager 2 cameras recorded discrete cloud features in Neptune’s atmosphere.
