sun theory
Coronal Heating: The topmost part of a star's atmosphere is called the corona. It is made of plasma. The sun's corona spans millions of kilometers into space and is located above the chromosphere. The best way to view it is during a total solar eclipse when it spills over the moon's black figure. When something is far away from a heating element here on Earth, say, for instance, a furnace, it begins to cool down because it's not close to that main heating source. But the sun does something totally different that is often posed as a mystery. The sun's visible surface is 10,000 degrees Fahrenheit hot. Moving away from the blaze ought to bring things under control, right, as it is farther away from the heating source. But it simply doesn't. Instead, the corona, the upper atmosphere of the sun, sizzles at millions of degrees, which is 200 to 500 times hotter than the roaring fire below. This complex process of keeping the corona extremely hot while also being far aw
