Nuclear reactions, where hydrogen atoms are fused together to become helium, take place in thE core of the sun. The energy released in this process eventually becomes

It turns into light-emitting solar explosions

Explanation:

These explosions are very similar to hydrogen pumps, thus generating a large amount of energy to be released in said reaction, on the other hand it allows matter from the nucleus of the sun to enter a plasma state, that is, a consistency similar to plasma
