The Sun
The most important star in the milky way
The sun and it's layers
The sun has layers, just like earth
The layers of the sun from the outer most layer to the inner most layer is...
- corona
- chromosphere
- photosphere
- convection zone
- radiation zone
- core
There are other things that happen/are on the sun like...
- sunspots
- prominence
- flares
- it's aurora
The corona
The sun's corona extends millions of kilometers into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph.
The chromospere
At the higher temperatures of this layer, hydrogen emits light that gives off a reddish color.
This colorful emission can be seen in prominences that project above the limb of the sun during total solar eclipses.
This is what gives the chromosphere its name (color-sphere).
The photosphere
The convection zone
In the convection zone, hot plasma rises, cools as it nears the surface, and falls to be heated and rise again.
The radiation zone
Energy travels through the radiation zone in the form of electromagnetic radiation as photons.
The core
These reactions release the energy that ultimately leaves the surface as visible light.
These reactions are highly sensitive to temperature and density
Sunspots
They correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

Prominence
Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.
Flares
(the bright lights)
Aurora
It is caused by collisions between air molecules and charged particles from the sun that are trapped in the earth's magnetic field.
