How do stars generate heat and light
WebMar 31, 2024 · Heat generates pressure, and the pressure created by a star’s nuclear burning also keeps that star from collapsing. A star is in balance between two opposite forces. … WebAll stars generate energy deep within their cores by one of the most powerful processes in the Universe: nuclear fusion. Hydrogen nuclei smash together, forming helium and releasing huge amounts of energy. This is why a star shines. The pressure of the gas heated by fusion supports the star against its own gravity.

Fusion reactions are the primary energy source of stars and the mechanism for the nucleosynthesis of the light elements. In the late 1930s Hans Bethe first recognized that the fusion of hydrogen nuclei to form deuterium is exoergic (i.e., there is a net release of energy) and, together with subsequent nuclear reactions, leads to the …
