  • What do stars do with their energy?

  • Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom 鈥?plus a lot of energy, which is released as light and heat. Stars can squeeze various types of atomic fuel together, and it鈥檚 through this process that we get almost every element in the universe.

  • How do stars affect our bodies?

  • Stars created everything else, including most of the atoms in your body. The energy that process releases is actually what keeps the star鈥檚 gravity from collapsing it entirely. A star lives while there鈥檚 balance between the outward push of energy from nuclear fusion and the inward press of gravity.
