There are billions of stars in the universe. Stars are massive, energy-filled globes of fiery gases. The force of gravity holds these gases together. At a star’s core, atoms of hydrogen join together to form helium in a process called nuclear fusion. The energy generated by this process produces a star’s heat and light. Collections of stars are called galaxies, and each galaxy contains many different types of stars.
