Bad Astronomy | Neptune s huge dark storm changed direction and no one knows why

When Voyager 2 passed by Neptune in 1989, the images it returned surprised scientists; it saw an immense oval dark storm in the planet s southern hemisphere as big as Earth itself! Called the Great Dark Spot, it had measured wind speeds of a staggering 2,100 kph, the fastest wind ever measured in the solar system. Zoom In The sizes of Earth and Neptune to scale.
