What are the Northern Lights?
The northern lights are beautiful displays of pale, flickering colours that can sometimes be seen in the night sky in far northern regions. Their scientific name is the aurora borealis, and a similar effect occurs in the far south, where it is called the aurora australis.
Auroras occur high above the Earth, between about 97 and 1,000 km above the surface. They are caused by electrically charged particles from the Sun that travel through space and collide with gases in the Earth’s atmosphere.
When these particles strike the atmosphere, they release energy in the form of light, creating glowing waves of green, red, and purple in the sky. Auroras are more common when there are many sunspots, as these increase the amount of energy and particles released by the Sun.
