In modern culture, the aurora remains a popular subject for photography, tourism, and scientific research, symbolizing the awe-inspiring power of nature.

More Information

The aurora is a natural phenomenon that occurs when charged particles from the Sun interact with Earth's magnetic field and atmosphere. This collision causes atoms in the atmosphere to emit light, creating the colorful displays we observe as the aurora borealis or aurora australis. These displays are most commonly seen near the Earth's poles, although they have been observed at lower latitudes during intense solar storms. The study of auroras has led to significant advancements in our understanding of Earth's magnetosphere and the Sun-Earth relationship.
