The key to all life forms.
Inside the Sun
The Sun's Core
The sun's core is a whopping 15,600,000 degrees Celsius. In the core nuclear reactions consume hydrogen to form helium. The reaction releases energy that ultimately breaks through the surface and makes visible light.
The Radiative Zone lies between the innermost core and the outer convective zone. In this layer energy is generated by nuclear fusion, energy is conveyed by protons.
An area of turbulent plasma in between the sun's core and visible photosphere. Here, energy is transferred by convection.
The photosphere is the visible surface of the sun. It is about 100 km thick, very thin if you were to compare it to the rest of the sun.
The Chromosphere can only be seen on a total eclipse, where it's red color is revealed, otherwise it's invisible. It is about 2,000 km deep and lies above the photosphere.
The Corona is an aura of plasma that surrounds the sun. It goes on for millions of kilometers and it most well seen in a solar eclipse.
Sunspots occur on the photosphere layer of the sun. They are dark spots compared to the area around them. Magnetic field flux that inhabit convection occur are the end result is a cooler surface temperature than the are surrounding.
A prominence is a big, bright, gas-like thing that goes outward from the sun's surface. Most likely, in the shape of a loop.
Solar flares are created when magnetic energy from the solar atmosphere that has built up is suddenly released. This causes radiation to be emitted.
A natural light display in the sky.
