Nuclear Fusion in the Sun: Powering Our Star

  1. The Sun shines by fusing hydrogen nuclei into helium deep in its core.
  2. This fusion process releases vast amounts of energy as light and heat.
  3. Every second, the Sun fuses about 600 million tons of hydrogen.
  4. A tiny fraction of mass is converted into energy via Einstein’s E=mc².
  5. Extreme pressure and temperatures over 15 million °C make fusion possible.
  6. The Sun’s fusion follows the proton-proton chain reaction.
  7. Neutrinos created in fusion escape instantly, offering clues about solar activity.
  8. Fusion energy takes tens of thousands of years to travel from the core to the surface.
  9. The Sun’s stability depends on a delicate balance between gravity and fusion pressure.
  10. Studying solar fusion guides humanity’s quest to replicate it for clean energy on Earth.
