How does a star die?

 Q:   Ask a Question about How does a star die?       
How does a star die? Stars die when they eventually use up all their fuel and burn out, but this process takes many millions of years.
Towards the end of its life, a star starts to run out of hydrogen to power its nuclear fusion. It starts to cool, becoming a red giant. The red giant swells, and the pressure at its centre becomes so great that the star begins to absorb energy instead of emitting it.
In a matter of seconds the star collapses, then explodes into a supernova. This is a huge explosion of light and energy that can be seen right across the galaxy.

Our Sun is part of the Milky Way, a huge disc-shaped collection of billions of stars and interstellar debris. Most of these stars cannot be seen with the naked eye but their combined light produces a huge milky-looking path across the night sky.
