The Great Dark Spot (also known as GDS-89, for Great Dark Spot, 1989) was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. In 1989, GDS-89 was the first Great Dark Spot on Neptune to be observed by NASA 's Voyager 2 space probe.

2019年3月25日 · Scientists dubbed the storms “The Great Dark Spot” and “Dark Spot 2.” Just five years later, in 1994, NASA’s Hubble Space Telescope took sharp images of Neptune from Earth’s distance of 2.7 billion miles (4.3 billion kilometers).

2019年8月22日 · This picture of Neptune was taken by Voyager 2 less than five days before the probe’s closest approach of the planet on Aug. 25, 1989. The picture shows the “Great Dark Spot” — a storm in Neptune’s atmosphere — and the bright, light-blue smudge of clouds that accompanies the storm.

1999年8月30日 · This photograph shows the last face on view of the Great Dark Spot that Voyager will make with the narrow angle camera. The image was shuttered 45 hours before closest approach at a distance of 2.8 million kilometers (1.7 million miles).

2023年8月25日 · Giant gaseous planets in our solar system, including Neptune, are known for the dark spots that appear in their atmospheres, such as Jupiter’s Great Red Spot, a centuries-old storm. This...

The Great Dark Spot is thought to be a hole in the methane cloud deck of Neptune. The spot was seen at different times with different sizes and shapes. The Great Dark Spot generated large white clouds at or just below the tropopause layer [2] …

The largest, called the Great Dark Spot because of its similarity in latitude and shape to Jupiter’s Great Red Spot, is comparable to Earth in size. It was near this storm system that the highest wind speeds were measured. Jupiter’s Great Red Spot has …

Neptune’s Great Dark Spot was not discovered until NASA’s Voyager 2 probe flew past the planet in 1989 on its way to the edge of the Solar System. Decades later, scientists are still unsure how...

The Great Dark Spot was a huge spinning storm in the southern atmosphere of Neptune which was about the size of the entire Earth. Winds in this storm were measured at speeds of up to 1,500 miles per hour. These were the strongest winds ever recorded on …

The Great Dark Spot (also known as GDS-89) is the name given to a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. The first one was observed in 1989 by NASA's Voyager 2 probe. Like Jupiter's spot, they are anticyclonic storms.
