What Makes the Northern Lights Happen?

The Northern Lights happen when particles from the sun dance with gases in Earth’s atmosphere.

Imagine you have a bag of marbles, these are like charged particles from the sun. The sun sends them flying toward Earth, and sometimes they zoom through space like a fast-moving stream.

When those marbles hit Earth’s atmosphere, which is like a blanket of air around our planet, something fun happens. Some of the marbles bump into gases like oxygen and nitrogen, think of them as sleepy friends who suddenly get wiggly when they're bumped.

These gas particles start to glow because they’re excited, kind of like how your face lights up when you laugh really hard. Each color comes from a different gas: green is usually from oxygen, and red or purple might come from nitrogen.

All these glowing bits create the Northern Lights, which look like ribbons of light painting the sky, just like how paint splatters on canvas, but with light!
