The Northern & Southern Lights (Auroras)

Part 1: What Are They? 🌎

The Northern Lights (Aurora Borealis) and Southern Lights (Aurora Australis) are beautiful, colorful lights that dance across the night sky near the North and South Poles. 

They look like glowing green, pink, or purple curtains or ribbons. They are not stars, planets, or meteors—they are a light show that happens inside Earth's own atmosphere.

Then, about 13.8 billion years ago, the little bald bubble began heating up and generating energy until it finally exploded with a bang. Today, we call this massive explosion the Big Bang.
