Stars are enormous spheres of hot gas that shine by generating energy through nuclear fusion in their cores. Most stars are made primarily of hydrogen and helium. In the center of a star, intense pressure and temperature cause hydrogen atoms to fuse into helium, releasing a tremendous amount of energy as light and heat.
