While orbiting 216 nautical miles (400 km) above earth, astronauts and cosmonauts had this view of aurora borealis above Canada. Auroras are a weather phenomenon caused by electrically-charged electrons and protons colliding with neutral atoms in the upper atmosphere. From space, the aurora show appears to blanket Earth with dancing lights.
