Explanation / Answer

Nuclear fusion is the source of all the energy that the Sun releases into space and this process begins right in the core of the Sun. The energy generated by fusion makes its way from the core towards the radiation zone as photons. These photons bounce around til they reach the top of the radiation zone and then the plasma absorbs these photons as the temperature cools down. Finally it finds its way up through the convection zone till the hotter gases drift up and the energy escapes into the surface of the Sun or the photosphere.

This entire process takes upto hundreds and thousands of years.

Photons take hundreds of thousands of years to get out of the Sun because their paths zigzag repeatedly.

Because the plasma is so dense, photons can only travel a fraction of a millimeter before colliding with an electron and deflecting into a new direction.
