133 days on the Glowing surface of "SUN" (4K)

The Sun's surface is primarily composed of hydrogen and helium, and the main gas reaction that occurs there is nuclear fusion. The dominant fusion process in the Sun is known as the "proton-proton chain," and it can be summarized as follows:

1. Proton-Proton Chain (PP Chain):
- Step 1: Two hydrogen nuclei (protons) collide and fuse to form a deuterium nucleus (one proton and one neutron), releasing a positron and a neutrino as byproducts.
- Step 2: A deuterium nucleus combines with another proton to form helium-3 (two protons and one neutron), releasing a gamma ray.
- Step 3: Two helium-3 nuclei collide, and one of them captures two protons to form helium-4 (two protons and two neutrons), while the other helium-3 nucleus is left with only one proton. This releases two protons.

Overall Reaction:
4 hydrogen nuclei (protons) -> 1 helium nucleus (helium-4) + energy

This continuous process of nuclear fusion in the Sun's core converts hydrogen into helium, releasing an enormous amount of energy in the form of light and heat. This energy is what powers the Sun and provides the heat and light that sustain life on Earth through the process of radiation from the Sun's surface.
