The northernmost part of the world has mysterious and beautiful natural scenery. That's the Northern Lights, like a curtain of color in the sky. They sparkle in attractive colors such as green, blue, purple and more. It's really fascinating. The Northern Lights, also known as the Aurora Borealis, is an optical phenomenon that appears in the night sky over the Arctic region. Its formation is related to the solar wind and the Earth's magnetic field. When charged particles in the solar wind are directed toward the poles by Earth's magnetic field, these particles collide with gas molecules in the atmosphere. This causes the gas molecules to become excited and emit light.
