How Does the Sun Generate Its Energy?

šŸ’” The Answer

  • The Sun fuses hydrogen into helium in its core via the proton-proton chain reaction.
  • Each second, about 600 million tons of hydrogen are converted into helium, releasing enormous energy.
  • The energy travels outward as gamma rays, but it takes over 100,000 years to reach the surface.
  • Neutrinos from the core escape almost instantly, providing direct evidence of fusion.
