Describe the birth of a star
WebThrough ‘Nuclear Fusion’ the star is born, and what happens through the stars life depends on the size of the star when made. What we know happens to all stars is that when the hydrogen gas runs out which causes the star at its core to collapse, the star starts to use the helium gas and other elements. WebWhen a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. The death of massive stars can trigger the birth of other stars. Neutron stars are the fastest-spinnng objects in the universe.
