The Sun and It's layers

The sun is a fantastic place, learn about it here!

The sun

Most people say the sun is a giant ball of gas made from hydrogen and helium. While the sun is hydrogen and helium the sun is actually mostly plasma! This is because the sun is so hot that the gas has turned into plasma, another example of plasma is lightning which can heat the air to an astonishing 18,000-60,000 degrees Fahrenheit! As you can see plasma is very hot which helps explain how powerful nuclear fusion(the thing that helps "power" the sun by combining hydrogen together to make helium) is.

Layers of the sun

The inner-most layer of the sun is the core. The core is where most nuclear reactions take place in which the hydrogen is consumed and turned into helium. The next layer is the radioactive zone. The radioactive zone gets it's name from the way energy travels through it, radiation. The energy produced in the core is carried by light, photons. Even though the energy travels at the speed of light the photons bump into each other so often it takes about a million years for the light to reach the next zone, the interface layer. This is a thin layer but it is thought that the sun's magnetic field is produced by magnetic dynamo in this layer. The next layer is the convection zone and it is the outer-most layer of the interior of the sun. At the base of the convection zone it is 2,000,000 degrees Celsius which is apparently "cool" enough for the heavier ions such as nitrogen and oxygen to hold onto some of their electrons. This makes it harder for radiation to get through and causing this layer to trap the heat. The next layer is the photosphere which is the visible part of the sun. This is a thin layer and the one we are most familiar with. The chromosphere is a layer on a sun that can only be seen during a solar eclipse. This layer burns at 6000 degrees to 20,000 degrees Celsius which gives the hydrogen a red, glowing color. This is the outer most layer of the sun and is in fact not really a part of the sun. This is more of the extended atmosphere on it and can only be seen by human eyes during an eclipse.
