Early in the history of the universe, before stars and planets existed, giant clouds of hydrogen and helium began to form. Slowly, these clouds collected enough mass for their own gravity to form. This created extremely dense balls of gas. In other words, they formed stars.

WebAug 8, 2024 · Stars form within giant clouds that consist of cold gas and dust. Slowly, gravitational attraction pulls far-flung specks of this gas and dust together, forming dense clumps in which material falls inwards, compressing to high densities and producing heat: a newborn star. Surrounding each of these "protostars" is a rotating disk of gas and dust. WebMain Sequence Stars A normal star forms from a clump of dust and gas in a stellar nursery. Over hundreds of thousands of years, the clump gains mass, starts to spin, and heats up. When the clump's core heats up to millions of degrees, nuclear fusion starts.
