Energy is released at the center of the Sun. This energy moves toward the surface of the Sun, and is spread in space as light and heat. The surface of the Sun is called Photosphere. There are dark spots on the Sun which are called Sunspots. There are thin gaseous layers above this celestial body which are called Chromosphere or the Sun’s gas rings, and which leave the Sun’s surface into the space. There is an aura of gas around the Sun called corona which can be seen only at poles. Atomic particles are emitted from the Sun like a current and reach planets including Earth. These currents are called solar winds.
