Under intense pressure and temperature, these atoms undergo fusion, combining to form helium and releasing energy. This energy provides an outward pressure, preventing the star from collapsing, thus creating a star.

They burn hotter and faster than smaller stars, undergoing fusion to create heavier elements. This fusion process continues until iron is formed. Beyond iron, fusion requires energy, leading to a supernova.
