Yes, Neptune does.
There is another smaller dark spot called The Small Dark Spot, a southern cyclonic storm, which is also the second-most-intense storm. It is intially dark, but has a bright center core. Other dark spots are formed in Neptune's troposphere.
Neptune
A type of hurricane. A transient one.
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.
Planet Neptune had a storm called the Great Dark Spot which disappeared. One of its 13 moons is also called Triton.
None. Saturn has a great white spot, Uranus has a dark spot. However, Neptune has a great dark spot [see related link for a picture] which has been compared to Jupiters great red spot, but it is not red.
It had a Great Dark Spot, which was a big storm, but it disappeared. A smaller one has shown up since.
The "black spot" you may be referring to is likely the Great Dark Spot on Neptune, one of the ice giant planets in our solar system. It is a large, rotating storm system similar to Jupiter's Great Red Spot. However, it should be noted that this feature has not been observed in recent years, suggesting it may have dissipated.
The Great Dark Spot on Neptune, similar to Jupiter's Great Red Spot, is a massive storm system on the planet's surface. It is estimated to be about the size of Earth. Therefore, you could fit approximately one Earth inside Neptune's dark spot.
One of the most unusual things about Neptune, I think, is the disappearence of The Great Dark Spot. It was thought that that was once a storm (or some time of weather activity) but when Voyager II passed by the planet and took pictures, the spot has faded and is almost gone.
Dark matter's strength is proportional to it's mass. This means that more dark matter in one spot is stronger then a little bit of dark matter in that same spot.
Yes, a storm had happened almost like the one in Jupiter, but it was called the great dark spot which was seen in 1989 then disappeared in 1994. :(
Neptune's atmosphere is notable for its active and visible weather patterns. For example, at the time of the 1989 Voyager 2, the planet's southern hemisphere possessed a Great Dark Spot comparable to the Great Red Spot on the planet Jupiter. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 km/h. Because Neptune is far from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures approaching at −218 C (55 K).
