DESCRIPTION: A ghostly iridescence - a magic light breaking the blackness of the polar night. The aurora - it has always struck people in the polar regions with awe. This is a visual journey around the globe. A journey departing from ancient myths and legends about the aurora, to scientific explorations of this natural spectacle. The source of the aurora is our sun - a celestial power that kindles a fire in the sky. When electrically charged solar particles hit the earth's atmosphere, lights will flare. When the sun's activity is increasing, the results are more intensive and more frequent northern lights. Even seasoned researchers never fail to be overwhelmed?
