Aurora

Aurora is a natural phenomenon that often occur in the North Pole. When it happens, the atmosphere emits colorful lights. Every time I see it,  I see it as a randomly generated abstract painting in the sky that changes simultaneously.
Every aurora picture you take, the result will be different. I think people under appreciate auroras because sometimes people see it as a regular phenomenon that only happens at the Earth's poles. I wonder what it will look like if the sun had auroras.
