Winter north of the Arctic Circle: Darkness, freezing temperatures, and stormy winds dominate the land.

But nature copes surprisingly well with the polar night. Plants alter their metabolism, polar bears flourish, reindeer eyes change so they can see well even in twilight, and dancing northern lights illuminate the sky. Let yourself be swept away into the life-threatening yet magical world of the polar night.

North of the Arctic Circle, the sun hardly ever sets in summer. 

Food is plentiful, but animals and plants face great challenges. Summer is short, and there's little time to raise a new generation. Around the clock, it's all about growing, eating, feeding, and hunting. But lack of sleep, mosquitoes, and the constant threat of predators spread hecticness and stress. Thus, deadly danger and abundant life lie close together in the realm of the midnight sun.
