What is supernova?

A supernova is like a giant star having the biggest party ever, and then exploding into space.

Imagine your favorite candy bar. It's full of energy and sugar, just like a star. Stars are made mostly of hydrogen, which acts like the sugar in the candy bar, it gives them energy. For most of their lives, stars burn this hydrogen slowly, like eating a snack.

But sometimes, a star gets really big and runs out of fuel fast. It’s like if you ate an entire candy bar at once, too much energy all at once! That makes the star swell up and then burst in a bright flash called a supernova.

When the star bursts, it sends out pieces of itself into space, kind of like when you throw confetti into the air. These bits can become new stars or planets, which means every supernova is like a giant star giving birth to new worlds.
