Scientific Explanation
The Northern Lights, also known as Aurora Borealis, are a captivating natural light display in the sky, primarily visible at high-latitude regions (around the Arctic and Antarctic). These celestial wonders are caused by the interaction between charged particles from the sun and the Earth’s magnetic field.
Interaction of Charged Particles and Earth’s Magnetic Field
The sun constantly emits a stream of charged particles called the solar wind. When these particles reach the Earth’s magnetic field, they are deflected towards the magnetic poles. As the charged particles enter the Earth’s atmosphere, they collide with gas molecules, primarily oxygen and nitrogen.
