This amazing wonder stretches for over 2,300 kilometers. It is home to more than 1,500 species of fish and 400 types of coral. The colors are incredibly beautiful—from bright blue to deep purple. Sadly, the reef is facing threats from climate change. Scientists are working hard to protect it.

What makes it so special First, the lights dance across the sky in beautiful colors—green, pink, and purple. They are caused by particles from the sun hitting Earth's atmosphere. This creates one of the most spectacular light shows on our planet. Many people travel far to witness this amazing sight.
