The Sun's Energy

In this video from NOVA’s Sun Lab, explore nuclear fusion and the balance of energy in the Sun. Intense heat and pressure in the Sun’s core cause protons to fuse together to form helium atoms, a process that releases large amounts of energy. This nuclear reaction—the same process that takes place in a hydrogen bomb—has powered the Sun for more than 4 billion years. The Sun does not blow apart from the outward pressure of nuclear fusion because the inward force of gravity balances it.

This video is available in both English and Spanish audio, along with corresponding closed captions.
