The Northern Lights

The Northern Lights If you take a trip to the Arctic region, in the Northern hemisphere you are likely to see a natural colourful display in the sky. This is known as the Aurora Borealis, which is Latin for Northern dawn. What causes the Aurora Borealis? These colourful lights are the result of interactions between solar storms from the sun and the earth's outer atmosphere. Btmosphere Earth's Solar storms During the day solar storms from the sun blow an array of particles, called Solar winds. The solar wind is like a burp given out by the sun from time to time. The earth comes in between the path of these șolar wind particles. These particles are filled with energy. Many electrons and protons from these particles get trapped in the polar regions of the Earth. The Earth's atmosphere is made up of two main gases, oxygen and nitrogen. These electrons and protons from the solar winds, full of energy, collide with the oxygen and nitrogen atoms in the Earth's atmosphere and they become electrically charged. · 02 This charging produces a display of lights in the sky- the Aurora Borealis. Special Features : The Aurora Borealis have been happening since ancient times. The earliest account can be found on a Babylonian clay tablet dating back to 567 B.C. They can either be static or travelling lights. and can occur up to 1000 kilometres. Most auroras occur at a height of 80+ kilometres above the earth! They can last for à few minutes to several hours. The aurora can be of a variety of • colours- red, green, brown, blue or a burst of colours together. 02 N Molecule Molecule The oxygen molecules in the earth's atmosphere are responsible for the green or brownish colours while the nitrogen molecules are responsible for the blue or red colours: Auroras occur usually around ring shaped regions, so they are seen around the two poles. Jupiter Saturn They have also been spotted on planets like Jupiter and Saturn. FUN FOR ME! MOCOMI Visit for more cool stuff! .com Copyright© 2014 Mocomi & Anibrain Digital Technologies Pvt. Ltd.
