Northern Lights are one of Earth’s most stunning natural spectacles that most people dream of watching at least once in their lifetime.

But what exactly is the Aurora Borealis? In truth, there is still a lot of mystery surrounding this marvel of nature.

However, it is understood that the phenomenon is caused by ‘solar wind’ – electrically charged particles that the sun flings across the solar system constantly – but with varying intensity.
The northern lights form when charged particles from the sun penetrate the earth’s magnetic field and collide with atoms and molecules to create bursts of light.

The particles are drawn to the earth’s magnetic fields around the poles, which is why they are visible at extreme latitudes (including the southern hemisphere, where they are called the Aurora Australis).

As they bombard the earth’s atmosphere, the particles ‘ionise’, releasing charges visible as light.
