Does the sum obey the 1st law of thermodynamics ? Please explain..

Dear Student , 
The First Law of Thermodynamics states that the total energy in a closed system remains constant over time. This applies to the sun as well.
First of all, there is no exceptions to conservation of energy, ie "Energy can neither be created nor be destroyed, it can only be transformed from one form to another".The sun is in a huge ongoing process of Nuclear fusion, in its core. Its a very complex process. But the basics is that matter gets converted to heat,light and other radiation. The energy generated is not stored anywhere on the Star, it id constantly being radiated away in a sense the star is the constant process of dying.
