Ariane - Aurora Borealis And Aurora Australis

Fantastic lights appearing in large circles around the North and the South Pole are called 

Aurora Borealis 

and 

Aurora Australis.

They are visible from

Alaska, Russia, Norway and Canada on the northern hemisphere and from

Antarctica, South America, Australia and South Asia 

on the southern hemisphere.

Only in recent times scientists have developed accurate theories on the origins of polar lights.

The powerful Sun wind interacts with the Earth´s magnetic field. Particles from the Sun collide with the atmosphere and cause the appearance of  light at the poles.

Sometimes the Sun wind causes real magnetic storms. These are powerful enough to knock out a power station on Earth or disrupt the function of satellites within the atmosphere. During a solar storm, the Taxi drivers in Sweden could hear the Taxi drivers over the mobile phones in Hamburg!

Auroras can be spotted on other planets with magnetic fields and atmosphere. For example, polar lights have been observed on Jupiter and Saturn.

The Aurora Borealis is like natural fireworks. It has beautiful colours like green, pink, brownish-red, yellow, purple or pure blue.

In the past people searched for answers for the appearance polar lights.

The Makah Indian tribes thought the Aurora was a dwarves´ fire. The dwarves were supposed to hunt whales and gather around the polar fire.

Please look at the photographs very carefully. Maybe you have seen these lights in films before.
