The stages below are not in the right order. Number the stages in the correct order.
The star begins to run out of fuel and expands into a red giant or red super giant.
Stars start out as diffused clouds of gas and dust drifting through space. A single one of these clouds is called a nebula
What happens next depends on the mass of the star.
Heat and pressure build in the core of the protostar until nuclear fusion takes place.
The force of gravity pulls a nebula together forming clumps called protostars. Hydrogen atoms are fused together generating an enormous amount of energy igniting the star causing it to shine.
