Post about Why are sunspots darker than surrounding areas

S because we have too many sunspots. Sunspots are the dark spots on the surface of the sun where the gases are so tight that they dont move, and the pressure is so great that they form a solid rock. In the picture below, the red spots on the Sun are the sunspots and the black spots are the surface of the Sun. In the middle area of the sun, we have a lot of activity as the activity of the Sun would cause the gas in the surface to move, and there is an excess of gas in that area. That means that it would be difficult to keep the pressure of the gas in balance because the gas is everywhere. When there is too many sunspots, the pressure is so great that the gas cant move. When there is not enough sunspots, the pressure is not too great. What makes the Sun dark is that the surface of the Sun is too hot and it gets too cold in the shadowed areas. The picture below is a view from above the surface of the sun:The other side of the Sun, is cooler than the area above it, so there is no sunspots. There is no shadow for the surface to form, so the surface just floats in the middle. Sunspots appear and disappear in a short time, but the dark spots never disappear because that would mean that the surface was never hot enough to form them. The only thing it means is that the surface is never really dark, it is the shadow that is a dark area, which is why the picture was taken from the surface of the sun so that the dark spots are clearly seen. Sunspots are also called black spots because they are blacker than other spots on the surface. Some theories say that sunspots make the Sun look dark because they let the heat of the Sun out into space. Some other theories say that the Sun is so bright that the heat is blocked out. The dark spot on the Sun means that the surface is hotter than the air, and it is also hotter than the Sun himself. Sunspots are not always dark, in fact some of them are transparent, which means that the Sun can pass through them. When there is a sunspot that is transparent, the Sun will appear to go through the window where you see the Sun. Sunspots will also become transparent, and the Sun will not appear to pass through the transparent area. When the Sun does not pass through, the opaque part of the spot is solid. The black spots on the Sun that are transparent, the Sun will not.
