What are stellar fusion processes?

Stellar fusion is like a super-powered kitchen inside a star, where atoms are cooked into new kinds of atoms.

Imagine you're in a giant kitchen, this is what's going on deep inside the Sun or other stars. Just like how chefs mix ingredients to make tasty food, stars mix atoms to create new elements, and in the process, they release heat and light, which is why we can see the Sun and feel its warmth.

Inside a star, there’s a lot of pressure and heat. This makes hydrogen atoms (the simplest kind of atom) bump into each other really fast. When two hydrogen atoms join together, they make a helium atom, and some energy is let out, like when you light a match and it releases a tiny bit of flame.

This process happens over and over again in the star's core, like a never-ending cooking show. The more fusion happens, the brighter the star shines. Some stars even go on to make heavier elements like carbon, oxygen, and even gold, just by keeping this party going for billions of years!
