The Aurora Borealis
Did you know that in Norse mythology, a sky phenomenon is considered a sign of an upcoming war?
The phenomenon is The Northern Lights or also known as the Aurora Borealis. It is a natural phenomenon that frequently occurs in boreal forests' sky on dark but clear nights without rain, with white, green, and purple, along with pink lights radiating across the horizon, transforming pattern and hue. The Aurora Borealis appears like clouds ranging from white into green into a vibrant purple-pink. It appears in various patterns, such as the shape of a curtain, ray, veil, or merely a beam of light on the skyline.
Although it is more visible at night, the trigger of the Aurora Borealis is the Sun. It merely transmits heat and light to Earth but sends many other energy and tiny particles. The Sun also releases large bubbles of electrical gas, which can travel within the cosmos at a rapid pace throughout a specific solar storm known as a coronal mass ejection. Meanwhile, magnetic field protection surrounding the Earth can block most of these particles and energies. Whenever such solar storms approach Earth, several Sun particles and energies move to the atmosphere at both poles of the Earth via lines of the magnetic field. At the poles, the particles interact with atmospheric gases, creating the light show to appear in the sky. Oxygen emits red and green light, whereas nitrogen emits purple and blue light.
The more northerly the latitude, the more significant the opportunity to see the Aurora Borealis. It is seen best in Alaska, Norway, Greenland, and northern Russia. Almost every clear night in the far north, the Aurora borealis can be seen. Some scientists maintain that the perfect period to see the Aurora Borealis is in early spring and autumn, around 10 PM to 3 AM, once the night sky is clear and dark.
In conclusion, despite its myth, the Aurora Borealis, or so it called Northern Lights, is a natural phenomenon in which the northern sky displays green, purple, pink, and white lights. It occurs when particles from the Sun's solar storm event are attracted by magnets at Earth's poles and interact with atmospheric gases, creating the light on the skyline. The Aurora Borealis becomes more visible when the sky is dark and clear between 10 PM and 3 AM in early spring and autumn than at other times.
