What Causes Auroras, and Why Do They Light Up the Sky?

Auroras are like light shows in the sky, and they happen when particles from the sun crash into Earth’s atmosphere. Imagine it like this: The sun sends tiny charged particles on a journey, and they travel through space until they reach Earth. When these particles hit gases in our atmosphere, they make the air glow with colors like green, pink, or purple. That glowing is what we see as auroras.
