Understanding Auroras: Nature's Spectacular Light Show

Auroras, also known as the Northern Lights, are stunning light phenomena caused by the interaction of solar winds from the sun and Earth's magnetic field. These colorful displays dance across the night sky, primarily visible from late autumn to early spring. Auroras typically last between 15 and 40 minutes, reoccurring every 2-3 hours. While they enchant observers, they can also disrupt radio communications and damage satellites. Many cultures have unique interpretations of auroras, linking them to legends and mythologies.
