The Aurora Borealis occurs when electrically charged particles from the sun (solar wind) interact with gases in Earth's atmosphere. Solar wind is deflected by Earth's magnetic field over most of the planet, but the magnetic field is weaker at the north and south poles allowing some particles to enter the atmosphere. We have seen mostly green auroras that are created when solar wind interacts with oxygen within 60 miles of Earth's surface, there have also been some hints of red light from the interaction with oxygen at higher altitudes.
