Imagine a star as like a giant balloon filled with hot air. Some balloons pop when they get too full, that's like a supernova explosion. Other balloons just slowly deflate over time, and that’s how some stars gently fade away. The difference between these two kinds of endings depends on what the star is made of and how heavy it is.
Examples
- A balloon pops loudly when it's too full, that’s how a big star explodes.
- Some stars are like firecrackers; others are just soft glowing lights.
