How Does a Star Die?

When the stars use up all their fuel, they burn out and eventually die. But the process would take millions of years.


The Stars usually consume all its hydrogen as it powers it nuclear fusion, it starts to cool, becoming a red giant. The red giant swells, and the pressure at the center becomes great that the star begins to absorb energy, in a matter of seconds, it will collapse and explodes into a supernova.


This supernova is a huge explosion of light and energy that can be seen across the galaxy.
