Detailed explanation-1: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
Detailed explanation-2: -Neutrinos can escape directly from the center of the sun, so solar neutrino experiments can “see” the core of the sun. Four experiments detect solar neutrinos, providing direct evidence that nuclear fusion occurs in the sun.
Detailed explanation-3: -The Sun shines by turning hydrogen into helium in its core. This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.
Detailed explanation-4: -Solar energy is produced by the sun itself via a process of nuclear fusion where the fusion occurs in the core of the sun. Due to the extreme temperature and pressure in the sun, the nuclei of hydrogen atoms fuse.
