Polar aurora

A polar aurora is like a big light show in the sky. It happens when electrically charged particles from the sun hit the Earth's magnetic field and get pulled toward the North and South Poles. These particles collide with the gases in our atmosphere, like oxygen and nitrogen, and make them glow different colors, like green, pink, and red. It's kind of like if you were playing with glow-in-the-dark toys and shining a flashlight on them at the same time. The result is a beautiful, wavy light display that people can see from far away. Sometimes people call it the "Northern Lights" or the "Southern Lights" depending on where they are in the world.
