Great Dark Spot. The Great Dark Spot in exaggerated color as seen from Voyager 2. 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 ...
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth and slightly more massive, but denser and smaller, than fellow ice giant Uranus.
The Small Dark Spot, sometimes also called Dark Spot 2 or The Wizard's Eye, was an extraterrestrial vortex on the planet Neptune. [1][2] It was the second largest southern cyclonic storm on the planet in 1989, when Voyager 2 flew by the planet. When the Hubble Space Telescope observed Neptune in 1994, the storm had disappeared.
The "Great Dark Spot," a storm in Neptune's atmosphere, and the accompanying bright smudge of clouds are captured by the NASA Voyager 2 spacecraft less than five days before its closest approach ...

Discovery of Neptune. New Berlin Observatory at Linden Street, where Neptune was discovered observationally. Neptune as imaged by the Voyager 2 probe in 1989. The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet ...
Uranus, when discovered in 1781, was the first planet discovered using technology (a telescope) rather than being spotted by the naked eye. Theoretically, in a typical dark sky, the dark adapted human eye would see the about 5,600 stars brighter than +6 m [6] while in perfect dark sky conditions about 45,000 stars brighter than +8 m might be ...
