Stains in Neptune. The Sun and the giant planets

Neptune has spots. This giant gas planet of the Solar System shows a clear blue hue, formed by small amounts of methane, hydrogen and helium in a thick, almost colorless atmosphere.

The dark spots that appear are anticyclones, high-pressure systems that spin between the cold clouds of Neptune. Two dark spots are visible in this photograph taken by the Voyager 2 robot in 1989.

With a size similar to that of the Earth The Great Spot is located on the left and the second on the bottom of the photograph. A bright isolated cloud Scooter accompanies the Great Dark Spot.

Recent computer simulations indicate that scooters are clouds of methane that could commonly be found near these spots.
