When the elements combine, they produce a nucleus with a mass lower than the sum of their masses. III. When there is an input of energy from nuclear fission reactions in the star, the elements are formed. IV. WebAstronomers estimate that the universe could contain up to one septillion stars – which in numbers is 1,000,000,000,000,000,000,000,000. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements.
