Solar flares are sudden variations in the brightness of a surface region of the Sun. Magnetic energy builds up in the solar atmosphere, above active regions, where sunspots are located. This magnetic energy is suddenly released as radiation across the entire electromagnetic spectrum.
The Sun is average star, but without its energy we would not exist.
An eclipse of the Sun, or Solar Eclipse, occurs when the Moon comes directly between the Sun and the Earth so that the Earth lies in the shadow of the Moon.
