Why Aurora Appears?

1) as a result of shooting from the sun to come close to the electronics of the deflection magnetic field, and concentrated into a spiral around the magnetic poles arising from the convergence effect. For the adoption of very thin and most of cold high gas discharge, resulting in the magnificent atmosphere luminous phenomenon. The shape of arch-arc, and so long with the mist, the state was from the beating, blinking into the explosion have. Aurora is usually white in color with green, with red, yellow, blue, with purple or pink, the duration from hours to several days ranging from 

   (2) why the aurora is only seen in the polar regions of Earth? Original Earth has a strong magnetic field, charged particles from the sun by the impact of the Earth's magnetic field, as the magnetic lines of the effects of convergence, the electronics and positive ions are posed by the gas (we call him for plasma) will be along the direction of the Earth's magnetic field lines generate a positive electric field, so the electronic plasma were accelerated in this field, enter the high latitudes of the ionosphere, so the only shooting at the polar regions of charged particles into the upper atmosphere can produce auroral . 

  (3) Geomagnetic North Pole in Canada (Geomagnetic North Pole from the geographic North Pole about 1200km away. Whichever is the center of the earth intersect about 11.5o.), It is in the northern part of southern Canada and the United States, common to the Aurora, Siberia low magnetic latitude to see less. Usually the higher the magnetic latitudes in order to see the Northern Lights, but closed on the intensity of solar storms in slightly lower magnetic latitudes can be seen. 

 Scientists have been able to correctly predict the eleven years for the cycle of solar storms, a large number of solar storms from the charged particles toward Earth, and to the interaction of the magnetic field produced splendid scenery of the Northern Lights. Eleven year cycle of the millennium coincides with the peak at slightly lower magnetic latitudes can be seen. . 

  (4) located in the Arctic known as the Northern Lights, is located in the Antarctic, known as the southern lights, just as the head angel halo general, set in the Earth polar night sky. Northern Lights and the Antarctic light can sometimes be like as the mirror image pairs.

Polar Aurora

Aurora (Polar aurora) high in the Earth's magnetic latitude areas. Is a gorgeous light-emitting phenomenon. From the Earth's magnetosphere, or the sun's energy flow of charged particles (solar wind) to enable the upper atmosphere of molecular or atomic excited (or ionized) arising. In addition, the number of sunspots, the Aurora also great frequency. 

   Aurora is a large-scale earth around the discharge process. Charged particles from the sun reach the earth near the part of the Earth's magnetic field along the magnetic force is concentrated to the north and south poles. When they enter the polar regions of the upper atmosphere when atmospheric atoms and molecules and stimulate the collision, resulting in light, the formation of the aurora. Aurora appears time is short half a minute long it will last for half an hour or even more than the speed of mobile Aurora is also some fast and some slow, in the process of moving, ever-changing patterns, but also to attract Aurora the local people! 

 Northern Lights Northern Hemisphere Southern Hemisphere Antarctic Light 

   Aurora most commonly found in the North-South magnetic latitude 67 ° near the ring with the two regions, namely light district known as the Antarctic and the Northern Lights District. The northern hemisphere to Alaska, north Canada, Siberia, the southern tip of Greenland and Iceland and Norway dominated the north coast; and the southern hemisphere are concentrated in the vicinity of Antarctica. It is worth mentioning is: near the North Pole, Alaska, Northern Canada is the best place to watch Aurora, Alaska Fairbanks (Fairbanks) has won the "capital of the Northern Lights" laudatory title, year, there are more than 200 days of the aurora .

Northern Aurora wonders

Finns are known as the Northern Lights Aurora borealis, thousands of years, has also attracted millions of people look up to heaven, marvel. 

 Mysterious Northern Lights 

 Nordic many ancient myths and legends related with the Northern Lights. It was believed to be the soul of those who died in the dance, also refers to the issue of female shield brilliance. 

 Finn called the "fox fire," said the fox running the sky, the tail aroused snowflakes in the moonlight reflection, is charming Symphony. 

 Enjoy the hot spots 

 Today, people can not necessarily on the causes of the Northern Lights have a hundred percent sure the answer, but the mysterious and beautiful phenomenon, but long ago the Arctic was in hot pursuit into the scope of precious natural wonders. There is no specific time for viewing the Northern Lights, according to the experience of September to March every year, the highest rate of the Northern Lights appear. 

 Location, away from city lights harassment is a necessary condition. According to statistics, the most northern part of Lapland have an opportunity to see the Northern Lights 3 / 4, East Lapland near the Russian border, 1 / 2, near the Arctic Circle or south of Finland and Central, the opportunity to see a 1 / 4. 

 If you would like to shoot a rare phenomenon must first prepare large aperture lens, a stable tripod and high-speed film (400 degrees or above); exposure time at least 15 seconds. Due to be waiting a long time in the wild, so necessary to wear adequate warm clothing. 

 Lapland in many places, but also the operations of tourism activities with people viewing the Northern Lights. Some appreciate turka hot colors such as Sally, but also has a glass top hotels, people look at this spectacle comfortable. Even ordinary hotels, Northern Lights will also be pre-weather cloth, or at night telephone notification service, you will not miss the opportunity to help.

Colorful Northern Aurora (2)

High latitudes of the Earth's upper atmosphere in the luminous phenomenon is the solar wind interaction with the Earth's magnetic field results. Scientists are of the view that: The electric solar wind particles collision with the Earth's magnetic field, guided by the Earth's magnetic field, the flow of the magnetic South Pole and the magnetic North Pole, from the ground in about 80 ~ 120 kilometers around, and the atmosphere of the gas molecules (especially nitrogen and oxygen) in collision of these air molecules are excited and luminous. 

 Aurora gorgeous, absolutely wonderful. This is because in the upper atmosphere contains different elements of the gas, which after the collision by the light. Usually the most common to see the Northern Lights is the green and yellow is the result of the section with energy particle collisions from the ground only 40 miles generated by oxygen molecules; when nitrogen molecules by particle collisions, will issue a red light; ionizing of nitrogen will issue a Blu-ray; and nitrogen and will issue a red light. Therefore, people can see red, blue, green, purple and white light covered the sky. 

 The emergence of Aurora need to have two conditions, first, the temperature must be low, and the other is better weather.

Colorful Northern Aurora (1)

Aurora is a bend in the sky to the extension of folding, it seems will be the flow of light, usually in the high latitudes of North and South latitude (especially the north and south latitude 67 degrees clitellum scope), easier to see, so called Aurora. In the Arctic near the Northern Lights are called, who called in the Antarctic near the southern lights. Eskimo population "Aurora " which means "goddess of the Department of Light." 

 High latitudes of the Earth's upper atmosphere in the luminous phenomenon is the solar wind interaction with the Earth's magnetic field results. Scientists are of the view that: The electric solar wind particles collision with the Earth's magnetic field, guided by the Earth's magnetic field, the flow of the magnetic South Pole and the magnetic North Pole, from the ground in about 80 ~ 120 kilometers around, and the atmosphere of the gas molecules (especially nitrogen and oxygen) in collision of these air molecules are excited and luminous.

Therefore, people can see red, blue, green, purple and white light covered the sky. Beautiful aurora also showed changes in the shape of infinity, a curtain-like, flared, ribbon and a variety of shapes, such as ray-like. 

 The strength of the solar wind and the sun's surface by the impact of the activities, the more active when the sun surface, the more sunspots or flares erupted, or coronal holes bigger issued to the stronger solar wind, the charged particles containing more; when the Shares in the more densely near the solar wind through the Earth, it will cause relatively Behind the Aurora, people can see even more spectacular than usual in the Aurora scene, or the lower-latitude regions will also appear Aurora. If by the end of October 2003 to early November, the sun's surface for several X-class Super flash flame and the phenomenon of coronal mass eruption, making even the latitude of the United States several times, only 40 Florida Buddha can see Aurora. 

 The emergence of Aurora need to have two conditions, first, the temperature must be low, and the other is better weather. There are a number of world countries will often Northern Lights, including Norway, Russia, Finland, Scotland, northern Canada and Alaska and other places, of which Finland is where Santa Claus Village. And Canada's Alberta Fort (Ft. McMurray) and Yukon province Whitehorse City In addition to relatively inexpensive price, the Aurora is the best viewing, the time for the annual October to April the following year.

Northern Lights veil Jie U.S. Space Agency launch a satellite research

The U.S. space agency, "the National Aeronautics and Space Administration" has launched a satellite loaded with 5 rocket lifted off from the first research project carried out the Northern Lights, hoping to solve a century the mystery of the Northern Lights. 

 NASA said in a statement that the period of two years, to be called "THEMIS" (Vice-time record of geomagnetic storms during the incident and macro-scale interaction studies) plan, after 24 hours of delay, was successfully launched last night rocket. 

 NASA Web site, said: "The space program will help solve the vice geomagnetic storms triggered the mystery of the phenomenon." 

 Department said: "The discovery of the space program will help to help protect commercial satellites and humans in space from the adverse effects of particle radiation." 

 Once deployed, the satellites will run every four days to the top of North America in order to observe the formation of the Northern Lights; such aurora is a polar region is located in the night sky, the dazzling light show. 

 On the ground, Alaska and Canada, observation station will be filming this colorful phenomenon of light and shade. 

 NASA THEMIS project leaders Snow said: "This is a challenging plan, will be a scientific explanation for this light to replace the traditional myth, which also provided a light clear evidence showing that the Earth the magnetosphere to protect us from the serious effects of the solar wind. " 

 Scientists hope that this joint operation of five satellites, able to identify the location of the Northern Lights have the exact location.

The world's natural wonders - the Northern Aurora

Northern Lights, since the formation of the Earth's atmosphere from the date on the fly in the sky. On the Northern Lights it many mysterious stories, many legends of the ancients show that fear of such a light. American Indians believe that as long as the whistle at the Northern Lights can bring spirituality order they do things. Nordic myth mentioned vengeful wizard will kill any person who laughed at the Northern Lights. For those ancestors, the brightness of the aurora is a strong Phytophthora, a harbinger of disaster and death. 

 Northern Lights can occur throughout the world, in particular, are known as "the dawn of God belt" or "the dawn of God oval ring" areas. In 1881, the Swiss physicist Buddha Leeds (Herman Fritz) in his book, "Aurora," said: "Northern Lights of the most dazzling spectacle is located near 67 degrees north of the sky." Norwegian scientists (Carl Stormer) in 1910 were declared to the world that often appears in the Northern Lights 100-120 km on the night sky. 

 Aurora arose because the sun's surface explosion released a large number of solar particles. Solar particles will be high speed (thousands of miles per second) through space. If the particle cloud near the Earth's magnetic field, the Earth will seize them and to push the Earth's magnetic field of the Antarctic and the Arctic, so the solar particles will not be consistent with the Earth's atmosphere in the gas molecules (oxygen and nitrogen) in the Northern Lights collision. Such a mechanism to protect the planet from destruction because the solar particles, but also to protect life on Earth. 

 Earth satellite photos showed that Aurora is continuing, but generally not strong to allow the naked eye can see. If the collision strength enough, in the clear night can see the aurora. Most dazzling Aurora appear in early spring or late fall. Midnight is the best time for viewing the aurora, experts will be selected before and after midnight the two hours viewing the aurora. 

 Aurora beauty lies in its night sky like fireworks. They look like colorful ribbons floating in the breeze. Usually the beginning of micro-light north, and then red, green, blue or purple as the flare across the sky like Block Arch. Northern Lights because of the Earth's magnetic field and the interaction between solar wind and continuing to move. 

 Churchill Northern Lights Canada photographic tour guides wearing ‧ Charlie (Richard Day), said: "In 2003 the first observation, the sky put on a few hours of light and colorful dazzling dance, better than I have ever seen of any man-made fireworks show." 

 The best areas for viewing the Northern Lights for the northern half of Norway (Svalbard is one of the world can be seen only during the day of the Aurora), Sweden, Greenland, Denmark, Alaska, Canada and Russia.
