These huge fusion reactors release a tremendous amount of energy. This energy is trapped inside the Sun for millions of years and constantly trying to get out.

Atoms are very, very small. A hundred million atoms placed side-by-side in a row would only be about 1 inch long! The simplest atom is hydrogen. The nucleus of a hydrogen atom consists of a single proton. Around this proton orbits a single electron. There is more hydrogen in the universe than any other kind of atom.
Helium is the second lightest or simplest atom. It consists of a nucleus containing 2 protons and two neutrons. Around the nucleus orbits 2 electrons. A helium nucleus can be created by smashing enough protons into each other that they fuse, or stick, together.
