How does nuclear fusion cause a star to shine
WebFeb 14, 2024 · The energy that process releases is actually what keeps the star’s gravity from collapsing it entirely. A star lives while there’s balance between the outward push of energy from nuclear fusion and the inward press of gravity. A star dies when it runs out of fuel and the balancing act ends. Read more: WebThe energy produced by fusion is then transported to the solar surface and emitted as light or ejected as high-energy particles. By the time the energy reaches the surface of the Sun, things have cooled down to 6000 degrees …

WebIf the star isn't large enough, nuclear fusion may stop, before the core of the star is fused to iron, since very high temperature (more than 2 billion Kelvin) and pressure are needed to fuse silicon to iron. This way the core may collapse earlier. The collapse releases energy responsible for much of the luminosity of the supernova. http://coolcosmos.ipac.caltech.edu/ask/2-How-does-the-Sun-shine-
