The process by which two atoms collide so fast they stick together and emit a great deal of energy. In the center of most stars, hydrogen fuses together to form helium. Fusion is so powerful it supports the star's enormous mass from collapsing in on itself, and heats the star so high it glows as the bright object we see today. Scientists here on earth are trying to make nuclear fusion in the laboratory a useful energy source.
