2014: Learn what the Northern Lights are and how they are formed

Everyone has always been fascinated at the Northern Lights. To see how the skylights and colored ink is a magical experience. It’s no wonder that the ancient Vikings and the northern towns considered them as a divine manifestation. But nowadays we know they are a phenomenon well understood in its basic principles. Do you also want to know them? Well then let’s go! It’s important to know the Northern Lights are only half of what really happens; Aurora Australis also exist and they take place and are visible from the South Pole. We know more about the Northern Lights because we are closer, but they’re not the only ones there. Both phenomena are produced by the same principles, which are in broad strokes the ionization of atmospheric gas due to solar wind and cosmic rays. The solar wind is composed of electrically charged subatomic particles that reach the Earth with high energy; meanwhile, also cosmic rays are subatomic particles coming with a […] Read More

2013: The Aurora Borealis and the Telegraph

by Patti Norton The aurora borealis is also known as the northern lights. This occurs in the sky of the northern hemisphere. (The same phenomenon occurs in the southern hemisphere, where it is named the aurora australis.) The aurora borealis is a glowing or flickering light of natural origin which is sometimes seen at night in the sky. In addition to the sun’s radiation, cosmic rays from outer space come pouring into the atmosphere. They create secondary radiations and electrified particles. Some cosmic rays fail to get through the atmosphere. The more penetrating ones traverse the entire thickness of our blanket of air and reach the earth. A large amount of meteoric matter is always falling through the atmosphere. The smallest pieces are no bigger than grains of dust, but they plunge into the atmosphere at speeds of 25 or more miles per second. The atoms of all elements […] Read More
