The Northern Lights official name is Aurora Borealis that light up the sky in the Northern Hemisphere. Aurora Australius is the official name for the Southern Lights are officially. The Southern Lights are not as well known because so much of the area near the South Pole is covered with water.
The Northern Lights are a natural light display in the sky that is created by the Solar Wind as it is passing Earth. The Southern Lights in the Southern Hemisphere are almost identical to the Northern Lights. The interaction between the gases in the atmosphere and the Solar Wind create the dancing lights in the sky at the North and South Poles.

People have watched the Northern Lights for thousands of years that live close enough to the magnetic North Pole to view the lights. The Ancient Chinese and Greek people wrote about the Northern Lights. The Eskimo's and Scandinavian's told oral stories about the Northern Lights for hundreds of years.
Today, people living in Europe can travel to the northern parts of Norway, Sweden, and Finland to view the lights. Iceland also have guided tours and self drive tours to view the lights.
People living in North American can visit Fairbanks, Alaska. Canada's Northwest Territories have places where you can watch the Northern Lights. The best months to watch the Aurora Borealis in these areas is February, March, September and October.
Pierre Gassendi in 1621 named the glowing lights in the sky. Aurora is the Roman goddess of dawn. Borealis is the Greek word for the north wind. Gassendi chose those two words because the Northern Lights are most active late at night or early in the morning when there is a new moon.

Intense solar activity creates large magnetic storms on the Sun during the peak of the eleven-year sunspot cycle. The electrons and protons in the Solar Wind are energy particles that increase during large magnetic storms on the Sun.
The Solar Wind takes two days to reach the Earth after the peak of the sunspot cycle. When the Solar Wind collides with gases in the Earth's atmosphere radiation is emitted as light. The electrons and protons are heated producing billions of tiny flashes of light that fills the night sky with the Northern Lights.
The Northern Lights are located from 80 km to 640 km (50 to 400 miles) above the Earth. They can last for several hours filling the sky with glowing and dancing curtains of green, pink, yellow and orange lights. Green is the most common aurora color and red is the rarest. Most of the time the Auroras last about 30 minutes.
There are few places to view the Southern Lights because South Pole is above the continent of Antarctica is surrounded by water. Most people in Antarctica are researchers and it would be very dangerous to camp on the ice on the continent to view the lights. Stewart Island in New Zealand and the Falkland Islands are two places where the Southern Lights can be viewed by people that want to see the Southern Lights.
