The Sun is a huge gas mass formed by an extraordinarily hot central core surrounded by successive layers that are colder or, rather, less hot. Next, come the radioactive and convective zones, through which and very slowly, solar energy is transferred to the outside.

Above them is the photosphere, which is the visible layer. The chromosphere is over the photosphere. Solar energy passes through this region in its path of sunrise. In these regions turbulence and sunspots occur.

Finally, the crown is the outer part of the Sun's atmosphere. It is in this region that solar eruptions appear. The crown can be seen only during the total eclipses of the Sun, and is not represented in this drawing.
