The Northern Lights, also known as Aurora Borealis, are a natural light display in the Earth's sky, predominantly seen in the high-latitude regions around the Arctic and Antarctic. The lights are caused by the collision of energetically charged particles with atoms in the high-altitude atmosphere. The resulting energy is released as a beautiful, glowing display of lights that can be green, pink, red, yellow, blue, or violet. The specific color depends on the type of gas particles that are colliding.
