Solar fusion proceeds through a three-stage process. First, two protons (hydrogen atoms stripped of their electrons) react to produce a deuteron, a positron and a neutrino. Then the deuteron, 2H, captures a proton to form the helium isotope 3He (helium-3), and then two 3He nuclei fuse to form 4He with the emission.

An important fusion process is the stellar nucleosynthesis that powers stars, including the Sun. In the 20th century, it was recognized that the energy released from nuclear fusion reactions accounts for the longevity of stellar heat and light. The fusion of nuclei in a star, starting from its initial hydrogen and helium abundance, provides that energy and synthesizes new nuclei. Differen

AI Customer ServiceThe processes by which stars, such as the Sun, produce energy is well-known to be based on nuclear fusion, and there has been a long-held ambition to reproduce this on Earth. The terrestrial abundance of the isotope of heavy-hydrogen, deuterium, makes this an attractive proposition for sustainable energy production.
By catching neutrinos emanating from the Sun’s core, physicists have filled in the last missing detail of how nuclear fusion powers the star. The detection confirms decades-old theoretical predictions that some of the Sun’s energy is made by a chain of reactions involving carbon and nitrogen nuclei.
This process fuses four protons to form a helium nucleus, which releases two neutrinos — the lightest known elementary particles of matter — as well as other subatomic particles and copious amounts of energy. This carbon–nitrogen (CN) reaction is not the Sun’s only fusion pathway: it produces less than 1% of the Sun’s energy.
Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.

The end of this chain is marked by the fusion of protons with beryllium-7 to form boron-8. This process is key in determining the flow of high-energy solar neutrinos that reach the Earth.
Nuclear fusion is the process that powers the Sun. It works by heating and forcing tiny particles together to make a heavier one which releases useful energy. If successfully scaled up to commercial levels it could produce endless amounts of clean energy without carbon emissions.
