The Enchantment of Auroras
Auroras, also known as the Northern and Southern Lights, are mesmerizing natural light displays that occur when particles from the sun collide with gases in Earth's atmosphere. These collisions produce a range of colors including green, purple, red, and pink. The lights are mostly visible near the poles, where Earth's magnetic field is weaker, allowing these particles to penetrate the atmosphere. The beauty of auroras is complemented by their dynamic nature, appearing as streaks or waves that dance across the night sky.
