How does nuclear fusion cause a star to shine

WebThe 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. WebThe sun, along with all other stars, is powered by a reaction called nuclear fusion. If this can be replicated on earth, it could provide virtually limitless clean, safe and affordable energy to meet the world’s energy demand. (Image: NASA/SDO/AIA) Five hundred years ago, the Aztec civilization in today’s Mexico believed that the sun and ...
