The Northern Lights are nature's most amazing creatures. The yellow, green, and red colors are due to the oxygen content of the air; the blue and purple colors are due to nitrogen. 

Arctic light occurs at the magnetic poles of the earth. This is not caused by light in the top layer of the atmosphere. Most of the solar wind coming to our planet is reflected. However, some still enter the Earth's magnetic field. These particles form light when they come into contact with air molecules at the top of the atmosphere (about 100 km above the Earth's surface).

The best time to observe the northern lights is about 9 to 10 hours after midnight during the winter months and in some cases up to 3 hours.
