The Midnight Sun or Polar Day is one of the spectacular characteristics of Polar Areas. Similarly, the Polar Night originates from the same physical characteristics of the Earth and its orbit around the Sun. Both the Polar Day and the Polar Night influence our circadian rhythms and, among other effects, present opportunities to enjoy for an extended period of time the moments when the sun is just above or just below the horizon. These are the moments when the colors of the sky are particularly beautiful. Help make this podcast sound better with a donation to the MARIO MICROPHONE FUND.
