The Northern Lights, or the aurora borealis, are an extraordinary phenomenon where waves of green, yellow and purple lights dance across the sky. They may seem like something out of a fairytale, but science has a dazzling explanation for it.
The phenomenon happens when solar wind, or waves of energised particles from the sun, crashes into the Earth’s upper atmosphere. They slam into the atmosphere at speeds of up to 72 million kph. Luckily for us, the Earth’s magnetic field protects us and redirects the particles to the poles of the planet. There are southern lights too, in the southern hemisphere, called the aurora australis. The particles transform into a spectacular atmospheric show that fascinates all who witness it.
