Planet Neptune had a storm called the Great Dark Spot which disappeared. One of its 13 moons is also called Triton.
The planet with a great dark spot that disappeared in 1994 was Neptune. The dark spot was a massive storm system in Neptune's atmosphere, similar to Jupiter's Great Red Spot. It was first observed by the Voyager 2 spacecraft in 1989 and had completely disappeared by 1994.
Yes, Neptune's dark spot is likely colder than its surroundings because it is a high-pressure storm system that rises from deep in the planet's atmosphere. The dark spot's formation is thought to be related to a huge vortex of frigid gases spinning in the planet's southern hemisphere.
The planet Neptune had a great dark spot. It soon vanished after discovery, leading astronomers to believe it was just a temporary storm, unlike the Great Red Spot on Jupiter which has been raging for hundreds of years. See the related link for more information.
The Great Dark Spot on Neptune is a massive storm system in the planet's atmosphere. It is similar to Jupiter's Great Red Spot but appears as a dark, swirling storm in the southern hemisphere of Neptune. The size and frequency of such storms on Neptune make it a dynamic and interesting planet to study.
