Webb11 apr. 2024 · Nuclear fusion is a reaction that occurs in the sun and other stars, and in turn, it makes energy. For the sun , the hydrogen molecules in its core collide due to the immense pressure and density. WebbIron fusion can take place in stars - what you need is lots of iron and very high temperatures to overcome the ever-increasing Coulomb repulsion between alpha particles and heavier nuclei. These conditions exist in the cores of massive stars near the ends of their lives. For example alpha particles can fuse with an iron-56 nucleus to produce …

WebbFusion is the most dominant reaction in our observable universe and it is the reaction that powers our Sun and the stars. However, the science and physics of nuclear fusion started becoming clear only in the 1920s when British astrophysicist Arthur Eddington suggested that stars draw their energy from the fusion of hydrogen into helium. Eddington's theory … WebbNuclear fusion releases energy, which heats the star and prevents it from further collapsing under the force of gravity. Astronomers call stars that are stably undergoing …
