The Sun's Layers
- Core - The innermost part of the sun, gravity presses hydrogen to form helium and release energy through nuclear fusion. It has an average temperature of 28 million degrees Fahrenheit.
- Radiative Zone - Less dense than the core, though it still takes light created by nuclear fusion 100,000 years to pass through it.
- Convective Zone - Above the radiative zone and less dense. This is where light energy is turned into heat energy, then it begins a process like boiling and creates convection cells.
- Photosphere - This is the deepest layer scientists can observe, and is covered mostly in granulation (bonded together particles)
- Chromosphere - Outside the photosphere, and gets hotter the farther away from the core in this section.
- Corona - This is the outermost layer of the sun, with no upper limit to it. It cannot be seen with the naked eye, except during a a total solar eclipse or with a coronagraph.
- Sunspots - A temporary phenomenon when parts of the photosphere are cooler than others
- Prominence - A large gas loop that extends from the photosphere that reaches to the corona
- Flare - Large bursts of radiation caused by released magnetic radiation from sunspots
- Aurora - Caused by a large gas cloud/CME from the sun colliding with the Earth atmosphere. It causes particles that are not seen by the naked eye to diffuse
