Cells can be stained in laboratory setting for contrast and better visibility under a microscope. One type of staining is called a gram stain. The cells take up the dying agent(s) in varying degrees, and often times, the nucleus of the cell stains darker than other cellular components. When viewing the stained cells under a microscope, it is possible to identify the cells nucleus by the presence of an elliptical, oval, or elongated darkened spot.
The dark spot seen in the nucleus in non-dividing cells where RNA for ribosomes is made is called the nucleolus. It is responsible for producing ribosomal RNA and assembling ribosomal subunits, which are essential for protein synthesis within the cell.

Yes it does. The spot is called 'The Great Dark Spot'
The names of Neptune's seas, or large dark spots, are: The Great Dark Spot The Dark Spot The Scooter The Small Dark Spot
The dark spot in the nucleus is called the nucleolus

Jupiter and Neptune have large dark spots caused by massive hurricanes. Jupiter's dark spot is known as the Great Red Spot, while Neptune's dark spot is called the Great Dark Spot.
Neptune has a massive anti-cyclonic storm system spanning 13,000 x 6,600 km It is called "The Great Dark Spot". There is also a smaller cyclonic storm in the southern region, called, not surprisingly, "The Small Dark Spot"
The Great Dark Spot on Neptune is a massive storm system, similar to Jupiter's Great Red Spot, that was observed in the atmosphere of Neptune. It is an atmospheric feature characterized by its dark appearance and is thought to be a large cyclonic storm. The Great Dark Spot was first observed by the Voyager 2 spacecraft in 1989.
No
Well, a sunspot is not really dark but it is at a lower temperature than the surrounding gases on the surface of the Sun. So it only looks dark by contrast with the area round it.
