Aurora borealis

Aurora borealis, also known as the Northern Lights, is a natural light display that occurs in the Earth's polar regions. It typically appears as colorful bands or curtains of light dancing across the night sky. The colors can range from green and pink to red, blue, and purple, creating a breathtaking and magical spectacle. The phenomenon is caused by the interaction between solar particles and the Earth's magnetic field, producing charged particles that collide with gases in the atmosphere, emitting light in the process.
