Answer:
Step-by-step explanation:
Stars are celestial objects that shine brightly in the sky. They are characterized by their immense heat and light. Stars are made up of hot, glowing gases, primarily hydrogen and helium, and their energy is produced through nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process.
Stars come in various sizes, from small ones called dwarf stars to massive ones known as giants or supergiants. They emit light and heat due to the intense temperatures at their cores. Stars play a crucial role in the universe, serving as the building blocks for galaxies and providing the energy needed for life to exist on planets.
