Ancient people worshiped the sun as a god. It was said that a solar eclipse meant the god was angry with them . It was also believed that the sun god's anger only could be calmed with prayer and sacrifice.
The sun has several layers: the core, the radiation zone, the convection zone, and the photosphere. There are two layers of gas above the photosphere called the chromosphere and the corna. Activities that occur on the sun include sunspots, solar flares, solar wind, and solar prominences.
