How Does the Sun Generate Its Energy?

💡 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.
