The Northern Lights, also known as Aurora Borealis, are a natural light display predominantly seen in high-latitude regions around the Arctic. They occur when charged particles from the Sun collide with gases in the Earth's atmosphere, creating vibrant colors like green, pink, and purple. These lights are best observed in places like Norway, Sweden, and Canada during winter months when the nights are longest. The phenomenon is not only beautiful but also a subject of scientific study, helping researchers understand solar activity and its effects on Earth.
