The Aurora Borealis, also known as the northern lights, is a natural phenomenon that captivates the hearts and minds of many. Each display of this mesmerizing event is unique, with an array of colors that light up the night sky. Charged particles from the sun collide with Earth’s atmosphere, causing these magnificent lights to come to life.
These charged particles interact with oxygen and nitrogen at different altitudes, creating a magical display of colors in the sky. Green is the most commonly observed color in aurora displays, caused by the collision of charged particles with oxygen molecules up to 150 miles above Earth’s surface. Red hues also appear, produced by oxygen in the highest part of the atmosphere at more than 150 miles above the ground. Purple and blue colors are linked to nitrogen, with purple lights appearing higher than 60 miles above the Earth while blue hues glow below this altitude.
During intense outbursts of the northern lights, spectators may be treated to an incredible sight as three or four colors illuminate the sky simultaneously.
