The aurora borealis, also known as the northern lights, is a natural light display predominantly seen in high-latitude regions around the Arctic. This phenomenon occurs when charged particles from the sun collide with gases in the Earth's atmosphere, creating vibrant colors like green, pink, and purple. The best time to observe the aurora borealis is during winter months when nights are longest and skies are darkest. Countries such as Norway, Sweden, and Canada are popular destinations for viewing this stunning spectacle, attracting tourists and scientists alike who wish to experience its beauty.
