How Does Fusion Power the Sun?

The Sun gets its energy from fusion, which is like a super powerful cooking recipe that happens inside it.

Imagine you have two tiny balls made of hydrogen, the most common element in the universe. These balls are really hot and move very fast, kind of like when you run around full of energy after playing at the park.

When these balls crash into each other, they stick together to make a new ball, helium. This sticking-together process is fusion, and it releases a lot of heat and light, just like how a sparkler makes bright light when it burns.

The Sun has tons of these hydrogen balls, all smashing into each other nonstop, millions of times every second. Every time they fuse, they release energy, so much that it keeps the Sun glowing and warm.

This energy travels through space to Earth, like a message in a bottle sent across the galaxy, giving us light and warmth for our day.
