On Sunday night, some lucky people in parts of the United Kingdom and Germany were treated to a rare sighting of the northern lights. The lights, also known as polar aurorae, appear when particles from the sun enter the Earth's atmosphere near the magnetic poles of the Northern and Southern hemispheres, colliding with oxygen and nitrogen particles that emit a range of light as a result. The colors of the aurorae depend on the types of gas particles involved and the altitude at which the reactio...
