The Aurora Borealis – commonly referred to as the Northern Lights – fired up once again overnight.
This phenomenon is a result of electrons colliding with the Earth’s atmosphere. The electrons become energized and follow the Earth’s magnetic field. As these electrons mix with oxygen and nitrogen in the atmosphere, the atoms and molecules enhance to a higher energy state. Once a critical buildup is reached, the particles release their energy in the form of light. According to NOAA (National Oceanic & Atmospheric Administration) this light that forms 80 to 500 km above the Earth’ surface is similar to how a neon light works.
The name Aurora Borealis was coined by Galileo in 1619. Aurora was the Roman Goddess of Dawn, and Boreas was the Greek name for the northern wind. The Aurora will be visible multiple times throughout the next three days. All of Alaska should have visibility if weather conditions remain clear, as should several northern states as well.
