This timelapse video was taken from Concordia research station in the Antarctic.<br /><br />Aurora Australis -- the Southern Lights -- occur over both the South polar regions, but are often difficult to see from populated areas. During periods of increased solar activity, the lights sometimes extend to populated latitudes.<br /><br />The laser beams are used as an experimental way of communication.<br /><br />During the winter, Concordia is under almost total darkness, with an average temperature of --51°C and a record low of --85°C. It is an ideal place to study the effects on small, multicultural teams isolated for long periods in an extreme, hostile environment.
