The Beauty of Northern Lights 

There are many beautiful places on the earth among which there is Aurora borealis which is also called as polar lights , aurora polaris or Northern lights .Aurora borealis is located in the high latitude regions of Norway and around the Artic and Antartic regions .  

Northern Lights may be visible withinside the northern or southern hemisphere, in an irregularly fashioned oval targeted over every magnetic pole. The lighting are regarded as `Aurora borealis` withinside the north and `Aurora australis' withinside the south. Scientists have discovered that during maximum times northern and southern auroras are mirror-like pics that arise on the identical time, with comparable shapes and colors.

 Because the phenomena takes place close to the magnetic poles, northern lighting were visible as a ways south as New Orleans withinside the western hemisphere, even as comparable places withinside the east by no means revel in the mysterious lighting. However the exceptional locations to look at the lighting (in North America) are withinside the northwestern components of Canada, specifically the Yukon, Nunavut, Northwest Territories and Alaska. Auroral shows also can be visible over the southern tip of Greenland and Iceland, the northern coast of Norway and over the coastal waters north of Siberia. Southern auroras aren't frequently visible as they're focused in a hoop round Antarctica and the southern Indian Ocean.

 Areas that aren't concern to 'mild pollution' are the exceptional locations to look at for the lighting. Areas withinside the north, in smaller communities, have a tendency to be exceptional.
You can see these lights near North and South Poles . In south pole these lights are called as Aurora Astralis or Southern lights . According to Norse Mythology this aurora is a bridge of fire which is created by Gods and According to some people this aurora is the spirit of their ancestors dancing in the sky . These lights are mostly visible in green color but we can also see them in pink and red color . The reason of  birth of these lights are not our ancestors , the reason is sun . Sun is the biggest fireball in which due to nuclear fusion Hydrogen atoms are converted into Helium atoms  due to which plasma state is formed . Plasma gas prances on upper layer of sun which creates large amount of magnetic field . Sometimes due to this magnetic field gases and charged particles move out from the solar layer which is also known as ‘ Solar flair ’ . These charged particles  reach earth’s atmosphere  after travelling two days from sun . Which is also called as ‘ Solar Wind ’ . If these charged particles collide with earth then it can destroy the earth . It can also destroy human life . The protective magnetic field of the earth protect us from these charged particles .

Earth’s surface is made up of three layers out of which there is one layer named core which consists iron alloy . Iron alloy helps in creating magnetic field around the earth . When magnetic field of the  Sun  tries to collide with the magnetic field of the earth , it collides with the magnetosphere of the earth and returns back . But , some part of the magnetic field manages to enter the earths’ surface because earth has two fragile points where magnetic field is fragile these two points are  North Pole and South Pole . When charged particle of the solar wind bump into the gas particles found in the earth’s atmosphere  they transfer their energy to the electrons of the gas . After getting energy electrons reach from lower orbit  to the higher orbit and when these electrons return again to their orbit they emit the energy , this energy is emitted in the form of photons or light particles . Mostly , these lights are observed in green or red color due to Oxygen and Nitrogen gas . Electrons of the oxygen gas emit green color and Electrons of Nitrogen gas emit red color . Green color is maximum because of large amount of oxygen . These lights are visible in round shape or look like curtain falling from sky . Aurora borealis is very beautiful and you must visit there to enjoy the beauty of dynamic patterns of brilliant lights .
