Auroras
An aurora occurs when the Sun's solar winds crash into the Earth's magnetosphere. They tend to look ghostly and somewhat creepy, although they are known to be quite beautiful as well. They move and change color in the sky. What is actually happening in an aurora is the Earth's magnetic field line is interacting with high-energy particles, or any particles from the solar wind. The charged particles will follow the magnetic field lines back down to Earth's surface, but they collide with things on their way. This results in a sort of light show. Different colors are created, and an amazing sight is developed! I would love to get the chance to see one someday.
