Aurora is a mesmerizing natural phenomenon that transforms the Arctic sky into a captivating canvas of colors and movement. Caused by the interaction between charged particles from the sun and the Earth's magnetic field, these ethereal lights captivate and inspire awe in all who behold them.
Harnessing Light for Sustainable Solutions
To appreciate the wonder of aurora, it's important to understand its scientific basis. Aurora are produced when charged particles from the sun collide with atoms and molecules in the Earth's upper atmosphere. These collisions excite the atoms, causing them to emit light. The different colors of aurora are determined by the type of atoms or molecules that are involved in the collisions.
Color of Aurora | Source of Emission |
---|---|
Green | Oxygen atoms |
Red | Oxygen molecules |
Purple | Nitrogen atoms |
Blue | Hydrogen atoms |
Yellow | Helium atoms |
