What happens inside a supernova? The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode! Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula.
How does a supernova release energy? This gravitational collapse releases an enormous amount of energy, more than 100 times what our Sun will radiate over its entire 10 billion year lifetime. This energy blows the outer layers of the star off into space in a giant explosion called a supernova (plural: supernovae.)
What keeps a supernova from collapsing? In the core of the star, hydrogen is fused into helium, releasing thermal energy that heats the star’s core and provides outward pressure that supports the star’s layers against collapse – a situation known as stellar or hydrostatic equilibrium.
What is a supernova made of? Iron atoms become crushed so closely together that the repulsive forces of their nuclei create a recoil of the squeezed core—a bounce that causes the star to explode as a supernova and give birth to an enormous, superheated, shock wave.
