Polar regions are known for unique natural phenomena that are hard or impossible to experience in other regions.
Northern lights and southern lights surround both the north and south magnetic poles. Cold clear nights are the best time to see them.
Halos of light or sun dogs can be seen anywhere but are most commonly seen in polar skies.
Sun pillars are pillars of light usually seen just after sunrise or before sunset.
Nacreous Cloud or Polar Stratospheric Clouds form in the Polar winters at very high altitudes.
