WebStellar nebula Moments after the Big Bang, energy begins to condense into matter, protons and neutrons are formed, and then the first element (hydrogen) is formed. Hundreds of millions of years later in stellar nebulae, the hydrogen gas clouds coalesce and, under gravity, form protostars.

Different stars take different paths, however, depending on how much matter they contain—their mass. WebA dwarf star's core can fuse hydrogen for billions of years before its lower atmosphere begins to boil. It swells into a red giant, then keeps expanding until its outer gases blow away. Left behind it a hot core that can no longer fuse, called a white dwarf. the hobo woods
