iss030e119777 (3/3/2012) --- A view of the night earth taken aboard the International Space Station (ISS) showing an aurora. An aurora sometimes referred to as polar lights, northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind.
