fusion reaction

A fusion reaction occurs when two light atomic nuclei combine to form a heavier nucleus. This process releases a significant amount of energy, which is the source of power for stars, including our Sun. In stars, the fusion of hydrogen nuclei forms helium under extreme temperatures and pressures. Fusion is seen as a promising clean energy source for the future since it produces minimal radioactive waste and requires abundant fuel, like isotopes of hydrogen. Efforts to harness controlled fusion on Earth aim to replicate this natural process for sustainable energy production.
