Sun Layers
The Atmosphere
Photosphere
This layer is the layer with the most density. It creates the photons that travel to Earth. This heat can travel in UV, visible light, and infrared radiation. This energy contributes to the photosynthesis of Earth. While a lot of UV light is intercepted by the ozone layer, this type of electromagnetic wave can harm the environment and cause many types of problems to human skin, especially skin cancer.
Chromosphere
The Photosphere affects the Chromosphere because it creates a great amount of heat energy in this layer. Jets of gas erupt from this layer, and it can cause damages to planets in the solar system. This layer has many sunspots, that can consequently originate solar flares.
Corona
This layer is the outermost layer, and it's the last layer of the Sun's atmosphere. This layer is the hottest part of the sun, and it extends into millions of kilometers into space.
The layers
The Core
In the Sun's core, nuclear fusion happens. This process is when there Helium and Hydrogen have contact and fuse together another heavier particle is created. This creates energy that results in visible light and heat, which passes through all the other layers of the sun.
Radiative Zone
The Radiative Zone is the biggest inner part of the sun, being 45% of the Sun's total mass. Energy is travelled by electromagnetic radiation as photons The photons travel through this layer by passing through processes called thermal conduction and radiative diffusion.
Convention Zone
In the convention zone, hot material from near the Sun's core rises, cools, and then goes back downwards to receive more heat that's in the radiative zone. This process makes solar spots and solar flares possible.

Sun's Cycle
The Sun is a sphere of electric-charged hot gas. The movement of this gas creates a solar magnetic field, that affects the solar flares to return to the Sun's convention zone. This movement of gas also makes the Sun magnetic field rotate, changing the positions of the north and south poles, when this happens the Sun has completed a cycle. Without the solar cycle solar spots wouldn't be formed and this would prevent eruptions that start on the convection zone.
Solar Life History
Main Sequence - The Main sequence is 98% hydrogen and helium. When the star runs out of hydrogen then the contact of the helium creates a red giant.The Sun can be considered one star of the main sequence.
Red Giant - There is expanding hydrogen in their cores, their outer layers can be extended to 100 times their original mass. This layers will expand so mu.ch that when they are separated into space a planetary nebula is formed. The Aldebaran star can be considered a red giant
Planetary Nebula - The ejection of the outer layers of a red giant form a planetary nebula, while the inner layers transform into a white dwarf. M27 can be considered to be a planetary nebula.
White Dwarf - This star core is composed of carbon and oxygen, but there is also the possibility of the elements helium, neon, and magnesium. When the white dwarf burns out of its hydrogen and helium, it stops emitting heat and light, so it transforms into a black dwarf. Mira B can be considered to be a white dwarf
Black Dwarf - When remains from the cooled white dwarf, is considered to be a black dwarf. It's life time is too short in comparison to the Universe to be able to prove its existence.
