The Sun's Layer

Inner layers

The Solar core The core is the Sun’s center zone where energy is produced through thermonuclear reactions which makes extreme temperatures of about 15000 C. These nuclear reactions needs to use hydrogen to create helium. The core extends to about one quarter of the way from the Sun’s center.

Radiation Zone In this layer, energy that has been made through Nuclear fusion in the core moves stably outside as electromagnetic radiation. It takes over 170,000 years to radiate through the radiation zone. In this zone, energy is moved outwards through radiation. It is carried by photon and is processed to bounce many times through zigzagging tracks. Convection Zone This layer of the sun is above the radiation zone and it is the last layer of the Sun’s interior. It stretches from deepness of about 200,000 kilometers up to the visible surface. Temperatures at the bottom of the convection zone are about 2000°C. Energy moves towards the sun’s surface. This happens when the solidity of the radiation zone becomes low enough. Heat from the edge of the radiation zones rises until it cools enough to sink back down. This pattern of heated material rising and cooling occurs in the convection zone cells.

Outer Layers

Photosphere This is the Sun’s deepest layer, and the layer visible to human eyes directly from the Earth. It is also called the solar surface. Basically everything part of this layer is covered by granulation caused by the bubbling gas within the convection layer and sunspots caused by strong magnetic fields. The Sun’s granulation has grainy aspect in the photosphere which has the appearance of bright cells with dark edges. The photosphere's temperatures depends from about 6500°C.

Chromosphere This layer of the Sun is located between 250 and 1300 miles above the photosphere. The chromosphere has temperatures around 4000°C. As a result, in this layer and other higher layers of the sun, the temperature increases if one moves away from the Sun, unlike in lower layers where it gets hotter if one gets closer to the Sun’s center. Corona This layer is the Sun’s outermost layer. It starts at about 1300 miles over the photosphere and it has no upper limit. Its temperature is between 500,000°C. The corona cannot be seen with bare eyes, but during a total solar eclipse one can use a coronagraph telescope to view it.
