The Aurora Borealis (Northern Lights) & the Aurora Australis (Southern Lights) are brilliant light shows in the earth's atmosphere. The auroras occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about 1 million miles per hour. When they reach the earth, they follow the lines of magnetic force generated by the earth's core and flow through the magnetosphere. "Green Vision" by Marc Adamus
NORTHERN LIGHTS The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south.
