The Northern Lights, or Aurora Borealis as the scientific term goes, are one of the most captivating natural beauties one can witness in life. They were originally named after Aurora, the Greek goddess of dawn. And when witnessing them in person, one can definitely understand how they came to be associated with divine connotations.
If you have never seen the northern lights in person or through image; picture a dark night sky with lengthy trails of neon green, blue, and violet blending together in a wonderful symphony. Ordinary rainbows are perhaps the closest natural phenomenon to this wonder, and a comparison to them really does not do the northern lights justice. They are definitely a sight that is necessary to witness at least once in everyone’s life.
The Scientific Explanation Behind Northern Lights
The scientific explanation behind the Aurora Borealis is actually quite complex. Charged particles traveling all the way from the surface of the sun hit the earth’s atmosphere and collide with the numerous gas molecules residing there. The atmosphere is made up of many different types of gaseous elements; and the type of gas that meets the sun particles causes the fascinating variation in color of the northern lights. Certain colors, such as the most common highlights of turquoise occur lower in the atmosphere, around 60 miles above ground-level. At higher altitudes the hues change and the pink tones can get up to 200 miles above ground-level. So there is a variation of both color and depth to the beautiful scene. Normally the earth has a magnetic field which deflects these particles before they reach the inner atmosphere. However, at the poles of the earth these fields are weaker. This is why the northern lights can only be witnessed in a limited number of key locations across the globe such as Finland, Norway – e.g. the Northern Lights and Article Circle by Rail tour, Scotland, Iceland, and Greenland.
