Aurora (Polar light, aurora) is due to charged particles the sun (solar wind) into the Earth's magnetic field, Earth's north and south poles in the vicinity of the high altitude, at night there's a brilliant beautiful glory. Known as the aurora australis in the Antarctic, known as the aurora borealis in the Arctic.

aurora have produced an early point in the past the theoretical point of view of modern scientific theory of the aurora aurora generation principle is clear evidence of the magnetic field energy into the classification of the aurora aurora can be classified according to morphological observation of electromagnetic waves by band divided by excited particles can be divided into regions according to the occurrence of auroras on Jupiter can be divided into other planets Saturn and Jupiter in the auroral formation process may be very similar to the legend of a Chinese legend and the legend of two Pittsburgh legends aurora aurora beauty of foreign observation sites additional information marketing team Aurora Aurora Aurora poetry music group music group member Aurora History Aurora Aurora music television network vulnerabilities Aurora Aurora RSAS QQ Speed Class B racing seventh Firefox browser versions - Aurora Chinese have information framework Aurora Aurora form

Aurora

Aurora varied, colorful, different shapes, very beautiful, yet in which the phenomenon of nature can match. It is difficult to draw any brush in the cold polar air play impermanence, the vagaries of the dazzling light. Aurora sometimes very short time, like holiday fireworks flashed in the air about disappeared without a trace; sometimes shine in the sky among a few hours; sometimes like a ribbon, sometimes like a cloud of flame, sometimes like a bright lights of the big screen; some color diverse, constantly changing; some only a silvery white, like cotton, white clouds, the solidification constant; some unusual bright, bright moon and stars Yan Qu; others and is very light, reminding us of scenes a beam black hair; some single structure, shaped like a curved arc, showing a light green, reddish hue; some threw the sky like a colored silk or ribbon, flying up and down, flip; some soft like gauze, breeze, showing a purple, dark red color; sometimes Aurora on the horizon, like a morning dawn; sometimes Tuyan Aurora such as camellias, a fiery red; sometimes close together with the aurora, like curtains, drapes; sometimes it fired a number of beam, like a peacock , Dieyi flying. Have generated Aurora Aurora (Aurora or Polar light or Northern light) appears in high magnetic latitudes of the planet over, is a colorful glow phenomenon. The Earth's aurora, the sun from Earth's magnetosphere, or the high-energy charged particles (solar wind) to upper atmosphere molecules or atoms excited (or ionized) generated. Aurora produces three conditions: atmosphere, magnetic field, solar wind. These three are indispensable. Aurora not only appeared on Earth, the solar system's other planets have magnetic fields also have aurora. Early view of many centuries, this has been speculation that the mystery and explore the heavens. In the past, Eskimos thought it was the spirits to guide the dead soul

Aurora

heaven's torch. 13th century, people will think it is the Greenland ice sheet reflected light. Of the 17th century, people call it the Northern Lights - Arctic Dawn (also seen in the Antarctic called the aurora light). As technology advances, more and more of the mysteries of the aurora as we know, the original, the beautiful scenery of the sun and the atmosphere out of work performance cooperation. Such as light and heat created by the sun and other forms of energy, there is a kind of energy known as the The solar wind is solar charged particles ejected, can cover the Earth is a bunch of powerful stream of charged sub-atomic particles, and thus belong to the plasma state. Solar wind flow around the Earth above the Earth to about 400 kilometers per second speed hit Earth's magnetic field. Earth's magnetic field such as the funnel-shaped, cutting edge facing the Earth's north and south poles, so the sun's charged particles along the geomagnetic field, the Poles of the upper atmosphere by the solar wind will be issued after the bombardment of light, the formation of aurora. Formation in the Antarctic region called the aurora. Formed in the Arctic called the Northern Lights. Scientific point of view in 1890, the Norwegian physicist Bo Kelan that 150 million kilometers from Earth, the sun almost continuous radioactive substances to the earth point. The 5 million km from Earth, to 6.5 million km away there is a layer covering the earth magnetic field, when the sun's magnetic field and particle direct this layer is blocked, it Pianxiang spread around the earth, looking for drill into the gap, about 1% of the results The particles penetrate into the atmosphere near the north pole. Each tablet contains the particle is equal to 1,000 volts solar power. They are outside the 100 km altitude in the atmosphere with most of the atoms and molecules of oxygen and nitrogen composition of encounter, atomic absorption part of the solar particles contained in the energy, this energy is released immediately turn generated a very strong light, Oxygen given the green light and red, nitrogen is issued purple, blue and some dark red light. These colors form a beautiful picture of the spectacular aurora. Currently, many scientists are making in-depth study of the aurora. People see the aurora, mainly in the electronic flow of charged particles caused. Moreover, the color and intensity of the aurora depends on the settlement of energy and particle number. With a vivid metaphor, can be said that the activities of Aurora activity as Ciceng live TV screen. Settlement of particles for the TV's electron beam, the Earth's atmosphere as a TV screen, Earth's magnetic field for the electron beam-driven magnetic field. Scientists from

Aurora

this natural big TV in the magnetosphere and the Sun-Earth space has been the electromagnetic activity of the large amounts of information. For example, the spectrum can be understood through the very source of sedimentation particle beam, particle type, energy, size, structure of the Earth's magnetic tail, and the planet's magnetic field Earth's magnetic field interactions, and effects of the sun disruption of the Earth's way and so on. Aurora Although beautiful, but cast in the Earth's atmosphere in the energy, power plants around the world with the capacity to produce electricity compared to the sum. This energy often confuse radio and radar signals. Aurora produced a strong current, we can pool in the microwave long-distance telephone line or affect the spread of the current in the circuit part or completely How to use the energy generated by the aurora benefit of mankind, is today an important scientific mission. The theory of the past in the past, some theories have been used to explain this phenomenon, but now are outdated. 1. The 杰明佛兰克林 (Benjamin Franklin) theory: The Magic of Northern Lights is a very thick area of charged particles and the strong role of snow and other moisture caused. 2. Auroral electron beam emitted from the sun. This is the Cleveland Christian Bo Kelan statement made in 1900, she was in a laboratory vacuum chamber and the magnetization of the Earth model, shows how the electronic guide is extremely area. The model itself is the lack of issues, including the aurora in the polar regions, the negative charge itself is self-scattering of these beams, and in the near future is still a lack of any observational evidence in space. 3 broken bucket theory: the aurora is the overflow of the radiation belts, which is about James Van Allen and working partners first proposed in 1962. They pointed out that in the radiation band soon gained tremendous energy in the diffuse aurora in the exhaust. Soon after, obviously trapped in the radiation energy of the band are positively charged ions, and in the Aurora is almost all low-energy electrons. 4. Auroras in the solar wind particles guided by the Earth's field lines to the top of the atmosphere caused, this applies to the cusp aurora, but in between the points, the solar wind has no direct role. On the other hand, both solar wind energy presence in the major positively charged ions, electrons only 0.5eV, while the sharp point rise to 50-100eV, which is still well below the energy of the aurora. The theoretical basis of modern U.S. National Aeronautics and Space Administration, Shiyou some distorted form magnetic field, charged particles of energy released in an instant to form a brilliant dazzling Northern Lights show, but the main only the Earth's aurora red, green two-color because of the heat into the layer of nitrogen and oxygen atoms are broken electronics collision, respectively, red and green light. The study was funded by the University of California, Los Angeles, Los Angelina Ropo hosted its findings was December 9, 2007 in the Joseph Smith's five satellite satellite missions group in February 2007 successfully launched in March in Alaska and Canada to the northern lights appear over the detection of two hours, at the same time the satellite has detected streams of charged particles come into contact with magnetic North Pole. And let Anji Ropo Los surprising is that the formation of charged particles and magnetic field exposure to geomagnetic storms per minute speed of 650 km passing air, the equivalent power of 5.5 Richter scale earthquake. Scientists have long suspected, the Northern Lights and Arctic energy charged particles from the magnetic field distortion produced by exposure to magnetic fields, but this theory has been only in May 2010 confirmed, Joseph Smith was the task of satellite constellation above the Earth more than 60,000 km from the first degree of distortion of the magnetic field measurements to the structure. Aurora is a large-scale earth around the discharge process. Charged particles from the sun reach the earth near the Earth's magnetic field along the magnetic field line to force a part of the (Field line) concentration to the north and south poles. When they enter the polar upper atmosphere, and atmospheric atomic and molecular collisions and to stimulate, generate light, the formation of aurora. Observed in the northern hemisphere called Northern Lights Aurora, Aurora, said the Southern Hemisphere observed in the Antarctic light, often places in the vicinity of 67 degrees latitude north and south of the two zonal regions, Alaska Fairbank (Fairbanks) year More than 200 days in the aurora phenomenon, known as the Aurora generates the principle is often seen in the auroral latitudes near the pole region of the atmosphere over the color luminescence. Zonal general, arc-shaped, curtain-like, radial, these shape changes are sometimes stable and sometimes for continuity. Aurora is charged from a solar active region of high energy particles (up to 1 million electron volts) flow to the upper atmosphere excited or ionized molecules or atoms generated. Due to magnetic field, these high-energy particles turn polar regions, so the aurora is common in high magnetic latitudes. Away from the pole at about 25 ° -30 ° range often appear Aurora, the area known as the auroral zone. The geomagnetic latitude 45 ° -60 ° between the area known as the

Aurora

weak auroral, geomagnetic latitude 45 ° below the area known as micro-auroral zone. Aurora height of the lower boundary, less than 100 kilometers from the ground, emitting a great height from the ground at about 110 km, the normal boundary from the ground up to about 300 km, in extreme cases up to 1,000 km. According to a recent study on the distribution of Aurora, not in the shape of the auroral zone geomagnetic very center of the circular ring, but oval. Aurora spectral line range is about 3100-6700 angstroms, the most important line is the 5577 angstrom green line of oxygen atoms, known as the aurora green line. As early as 2000 years ago, China began to observe the aurora, Aurora has a rich record. Solar wind carries particles into the Earth's polar magnetic field cutting the magnetic field lines emitted light: similar to Bremsstrahlung Aurora is the energy into the magnetic field of the clear evidence of Earth's magnetic field lines to carry the solar wind energy into the Earth's interior, which in turn drives the Earth's magnetic field formation. In this closed loop on the magnetospheric magnetic field lines in addition to conductors outside the Earth's interior, in addition to the atmosphere of the ionosphere - a weak conductor. When a strong solar wind, the magnetic lines of energy within the Earth's magnetic inductance encountered, many of energy consumption can not afford, so they formed in the ionosphere at Aurora. On Earth, auroras are magnetic phenomena over the area of the colored light. Zonal general, arc-shaped, curtain-like or radial. These shape changes are sometimes stable and sometimes for continuity. They have a colorful glory, like the flying ribbons, like a Miles Changhong. Away from the pole at about 25 ° ~ 30 ° will often appear within the aurora, or the region known as the auroral zone known as the auroral oval. Before accepted theory: Aurora is carrying solar wind of charged particles along the geomagnetic field, the Poles of the upper atmosphere by the solar wind will be issued after the bombardment of light, the formation of aurora. This explains the beginning feel quite a bit unreasonable, but careful analysis will find that this is simply not tenable interpretation. Solar wind of charged particles per cubic centimeter of only a few, is to let them all light, you can not see them. Moreover, let them go to hit the gas particles, they are hit probability is negligible. Say that the settlement of charged particles! Who let the same deposition of charged particles like dust, I can take a bottle to power up, and Oh. Aurora wanted to calculate the year Stormer charged particles, do not want it to go up early went to the radiation belts. Even before assuming all set up, according to the formation of charged particles hit the gas particle theory Aurora, aurora in the cusp should be a columnar body, and should not be a flat ring. And the flat part is that a strong magnetic field; flat ring - not in the auroral oval is also within the cusp, the solar wind is not reached there. There is flying north and south Aurora is the conjugate, which is electrically charged particles hit the gas particle theory can not explain the formation of the aurora phenomenon.

[1] the average solar wind speed is 400 kilometers per second, while the rate of change in the electromagnetic field is close to 30 million meters per second. If you see both north and south poles of the Aurora flying common image, no matter Aurora is Earth, Saturn, or Jupiter, that is a visual treat. Message-changing shape and color changes in Aurora, this is the speed of the solar wind can not do. Sometimes a change in attitudes will make people suddenly see the light, if the magnetic field lines carry energy at the formation of the aurora in the ionosphere to look at the interpretation of structural changes in the Earth's magnetosphere. We will find a lot of difficult problems can be resolved. For example, magnetic reconnection in space science, magnetic substorms, and many other questions debated for years to be able to straighten out the. Aurora by Aurora morphological classification can be divided into uniform arcs Aurora Aurora-ray beam ray-type optical arc-shaped curtain with aurora aurora aurora crown divided by band optical observations of auroral radio waves by auroral particles can be divided into electronic excitation proton aurora Aurora can be divided by region occurred with aurora aurora aurora in polar cap latitude auroral red arc on Jupiter's Aurora recently, the Southern European Observatory published in November 2002 to shoot photos aurora on Jupiter, and Jupiter over the poles smoke, which

captured Jupiter aurora

is the first time a clear shot to the poles of Jupiter. Jupiter (Jupiter) from the Earth (Earth) of about six hundred and ten million kilometers, in the past, scientists had to use space Administration (NASA) Hubble Space Telescope (Hubble Space Telescope), shoot to the Jupiter aurora (aurora) photo, however, Southern European Observatory using the (European Southern Observatory) IR (infrared) telescopes, scientists can more clearly observe Jupiter's aurora and the Arctic smoke (haze). Scientists pointed out that the aurora around Jupiter's magnetic axis is the (magnetic axis), and the smoke is around Jupiter's rotation axis (rotation axis), under the halo is in a very; smoke zone on Jupiter is subject to the wind (zonal winds) the impact of these areas the wind is in the same latitude (latitude) on the move; scientists believe that Jupiter to ten hours a rapid rotation, will also affect the movement of smoke over the poles. Other planets Jupiter and Saturn in the two planets are stronger than the Earth's magnetic field (magnetic field strength at the equator of Jupiter is 4.3 gauss, compared to the Earth is only 0.3 gauss), and both also have a strong radiation band. Hubble Space Telescope is also very clear to see that the two planets of Aurora [1]. In the gas giant planets and Earth's aurora appears similar to, but also provide energy from the solar wind, in addition, Jupiter's satellites, particularly Io, Jupiter's aurora is a source of energy. These currents along the field lines (field collimated current) Bay to give birth, and was prompted by the satellite revolution around the planet relative motion, caused by the generator mechanism. With volcanic activity and the ionosphere of Io, is a powerful source of charged particles, from the beginning of the study in 1955 by its current radio waves emitted by the radiation. Using the Hubble Space Telescope are Io, Europa, and the aurora observed on Gan Ni Mide, when Jupiter's magnetosphere plasma impact to their thin atmosphere, will produce the aurora. Venus and Mars have observed aurora. Because Venus has no intrinsic (planetary itself) of the magnetic field, Venus, Aurora presents different shapes and intensity, appear to be bright but diffuse patches, sometimes distributed across the planet's disk. Aurora Venus from impact and solar wind particles into the atmosphere in the night side. On August 14, 2004, instruments on Mars Express Mars Aurora SPICAM detected. This road is located in Aurora erra Cimmeria, longitude 177 °, latitude 52 °, the radiation area about 30 km miles wide, about 8 km height. Mars Global Tan Kanzhe by analysis includes crustal magnetic anomalies over the past number of data, scientists found radiation region is relatively local magnetic field is strongest regional areas. This correlation shows that electrons are magnetic field lines through the crust of Mars was inspired by the atmosphere and the movement. Saturn and Jupiter's aurora are very similar to the formation of Saturn's aurora may be made to launch a new study, found a two auroral oval ring (auroral oval), brightness is the main auroral oval

photographed Jupiter Aurora

ring a quarter. The main auroral oval ring than a decade ago for the first time in the Hubble Space Telescope images to see, then its shape has been determined in detail, but there has been controversy about its origin. One theory is that they see on the planet Aurora oval ring (mainly by the interaction with the formation of the solar wind) and Jupiter's auroral oval ring (from the interaction with the plasma stream to form) a hybrid between structure. But Saturn's auroral oval ring of the nature of the two shows that it is Jupiter's main auroral oval ring of a weak counterpart, the reason why it is relatively dark, because Saturn does not have a such a large ion source. It now appears that Saturn and Jupiter's auroral formation process is very similar, the appearance of difference is caused by the difference in scale. According to legend, Chinese legend legend a day over two thousand years BC, the night arrived. With the sun gone, the night was it the black wings in the vast open land, the mountains, close to trees, rivers and the mound, and everything all under the carpet. ② named Po with a young woman sitting alone in the wilderness, her eyebrows Bay under a general youthful passion shine on fire, apparently by this quiet night captivated. The night sky like a boundless sea, it is broad. Serene and mysterious. Sky, the stars twinkling, quietly overlooking the black ground, suddenly, in the constellation Ursa Major ③, the drift of a ray of light with a magical rainbow, smoke Si Wu, flickering, when the moving-quiet, like to fill the gap, and finally into a gigantic halo, lingering around in the Big Dipper. The time, sharply increased the brightness of rings, like a bright moon hanging in the sky, the earth under a light silver diarrhea Guanghua, Yingliang the entire wilderness. Looked around all things are clearly defined, overwhelmed see, everything has become a living. Seeing with treasure, one can not help but to move. This leads us pregnant, gave birth to a son. This boy is the Yellow Emperor Huangdi's. Above may be the world about the Aurora one of the oldest myths and legends. Legend of two old books in our country, The book has a fairy comes to the north, morphology, such as a red snake, sparkling in the night sky, it's called touch the dragon. Touch a dragon on the following description: Pittsburgh, Pittsburgh, USA magnetic latitude aurora is much higher than Beijing the opportunity to see most of the aurora. The evening of 7 November 2004, a strong aurora in Pittsburgh naked eye can see green, red. November 20, 2003 evening, the aurora appears in the horizon south of Pittsburgh, an hour later subsided. Reoccurred in the north at low altitude at night. 2003 October 30, Sunrise of Aurora is now Pittsburgh, although in the light polluted city, but still see the red light. The term foreign legend comes from the Latin Yiou Si Aurora term. Greek mythology, legend Yiou Si and the evening star and other stars of the mother. Aurora has also been said to be Orion's wife. In works of art, Yiou Si is said to be a young woman, she is not hand-pull a young boy walked swiftly to hurry, riding Pegasus is four-wheel drive vehicle pull from the sea to the sky ; Sometimes she is also portrayed as a goddess, holding a large water tank, extended wings, charity to the world the morning dew, as the story of China's Buddhist Goddess of Mercy, general sprinkled nectar to the world. Eskimos believe that Aurora is the soul of the dead spirits to guide the torch of heaven, as the indigenous people are the gods appeared as Aurora, Aurora will be convinced that the issue of fast-moving spirits in the air and stepping sounds, will take away a person's soul, leaving the fate. Aurora Aurora is not only the beauty of optical phenomena, and is a radio phenomenon, can be detected with radar research, it will emit some radio waves. Some people said, the aurora can be issued a variety of voices. Aurora is not only an important subject of scientific research, it also directly affects radio communications, long cables, communications, and long pipelines and electricity transmission lines and many other useful projects. Aurora can also affect the climate, the impact biological processes. Of course, there are still many Aurora did not shrouded in mystery. Aurora is considered the most beautiful natural wonders. If we rode the spacecraft, the Earth's poles across the sky, the earth from distant space, looked around the Earth's magnetic poles will see there is a shiny ring, this ring is called the aurora eggs. Because of their side of the sun a little flattened, and the back side of the sun is slightly stretched, thus showing the same shape of the egg. Aurora eggs in continuous change, when the Ming dark, sometimes extending to the equator, sometimes the ED also the direction of contraction pole. Midnight at the widest part of the halo appears brightest. Long-term observation results show that the aurora is most often where the magnetic north and south latitude, 67 degrees in the vicinity of two zonal regions, respectively, called the Antarctic Zone and the northern lights zone. In the Aurora area auroral activity occur almost every day. Aurora in Aurora

 

egg surrounded by the inner region, usually called the polar cap, in the region, rather than the opportunities Aurora lower latitude auroral zone far less. In low latitude areas, particularly near the equatorial region, rare aurora, but not to say that simply did not observe aurora. February 10, 1958 a large aurora night, could be seen in the tropics, and show bright red. The type of aurora is often associated with large solar flares and strong geomagnetic storm outbreak related. In the cold polar regions, people look up to the night sky, we often see colorful, varied, various shapes of Aurora. No exaggeration to say that the world simply can not find two exactly the same shape to Aurora, from the scientific point of view, it will be according to their morphological characteristics into five Aurora: One neat slightly curved bottom edge of the auroral arc-shaped arc; Second, there is bending and torsion of the ribbon-shaped crease auroral zone; third film in general as the clouds flower-shaped aurora film; Fourth, the veil of the curtains, as uniformity of the aurora-like mantle; Fifth, the direction of the rays along magnetic field lines like very light. Physical changes in the brightness of the aurora is great, just be visible from the galactic nebula-like brightness, always on the full moon when the moon light. In strong aurora appears, the outline of objects on the ground can see the illuminated, even the shadow of the object to illuminate. Aurora is certainly the most moving movement caused by the ever-changing wonderful sight. We often describe things very quickly, said: within minutes. Aurora changes in motion is the nature of this master of magic to the sky as the stage of a staged drama of light, hundreds of kilometers up and down the vertical and horizontal, and there is even ten thousand kilometers of the auroral zone. This magnificent natural scene, it seems like slightly moistened Xianqi, rather mysterious. Aurora is a breathtaking color, colorful long can not be used to depict. After all, the character is nothing more than red, green, purple, blue, white, yellow, but the nature of this super-artist with a superb technique, the depth of shades, dimly visible dark one with a combination of Goodfellas, about child into a kaleidoscope of friends. According to incomplete statistics, the aurora can distinguish colors has reached one hundred and sixty species. Aurora is so colorful, so changing, but also in such a vast expanse of the dome, the dark silence of the cold at night and uninhabited polar regions, it is only natural, at this moment, the face of the colorful aurora graphics, dear reader, you can not fascinating, not Jiaoren charmed it? No wonder so many polar explorers and travelers of the notes, the description of the aurora often seems dried Ciqiong language, but to say that kind of thing as a quibble. Yes, ordinary beauty, spectacular, wonderful and so are words in front of the aurora was extremely pale and weak, we can say, even if there is a gifted writer Ye look hard Shuyue Aurora, momentum, Bing Xing temper in the case. Most observation sites in Aurora --- 130 kilometers above the Earth 90. However, some Aurora is much higher. In 1959, a Northern Lights

Aurora

measured the height is 160 km, width of more than 4,800 km. On the horizon of the city lights and tall buildings may interfere with the light we see, the best scene of the Aurora open areas in the countryside can be observed. Churchill city in Canada, there are 300 nights a year in to see the aurora; in the state of Florida, only to see an average of four times a year or so. Mohe, the northernmost country, but also a good place to watch the aurora. Mid-18th century, a Swedish Geophysical Observatory, scientists found that when the station when the aurora observed on the ground, the compass direction of the pointer will appear irregular changes, changes in scope as much as 1 degree. At the same time, London's geomagnetic also recorded a similar phenomenon. Thus they believe that the appearance of the aurora and the geomagnetic field change. It turned out that Aurora is the solar wind with Earth's magnetic field interaction. The solar wind is solar charged particles ejected, when it is blown over the earth, will be the role of Earth's magnetic field. Earth's magnetic field such as the funnel-shaped, cutting edge facing the Earth's north and south poles, so the sun's charged particles along the geomagnetic field, the Poles of the upper atmosphere by the solar wind will be issued after the bombardment of light, the formation of aurora. Upper atmosphere is a combination of gas composition, the different elements of the gas emitted by the bombardment of light in front of the color is not the same. For example, oxygen is activated after the issue of green and red, nitrogen was issued after the purple laser light, argon laser issued after the blue light, the aurora becomes so colorful, constantly changing. Scientists have learned that Earth's magnetic field is not symmetrical. In the solar wind's blowing, it has become a kind of That side of the magnetic field lines toward the sun was greatly compressed, but in opposite directions out a long, tail shape of the Earth's magnetic tail. Magnetic tail length of at least 1,000 Earth radii long. As with the Sun-Earth space, the role of the interplanetary magnetic field coupling, the deformation of the Earth's magnetic field outside the poles to form a narrow, magnetic field strength of weak cusp. Because the plasma with a When the dramatic changes in solar activity (such as flares), often caused by the Earth's magnetosphere substorms. So these charged particles are accelerated along magnetic field lines and movement. Into the Earth's polar regions from these charged particles hit the upper atmosphere of the gas molecules and atoms, so that the latter is excited - the de-excitation and light. Different molecules, atoms of different colors of light, these monochromatic light mixed together to form colorful aurora. In fact, people see the aurora, mainly in the electronic flow of charged particles caused. Moreover, the color and intensity of the aurora depends on the settlement of energy and particle number. Use a metaphor, like the magnetospheric auroral activity can be said that the activities of live television. Settlement of particles for the TV's electron beam, the Earth's atmosphere as a TV screen. Earth's magnetic field for the electron beam-driven magnetic field. Scientists from the Natural big TV to get the magnetosphere and space on the electromagnetic activity of the large amounts of information. For example, the spectrum can be understood through the very source of sedimentation particle beam, particle type, size, energy, Earth's magnetic tail

Aurora

structure, Earth's magnetic field interaction with the planet's magnetic field and solar disturbing impact on the Earth way and so on. The formation of the aurora and solar activity are closely related. Fengdao great solar activity years, you can see even more spectacular than usual in Aurora scene. In the past, do not see many low-latitude auroral region, but also lucky enough to see the aurora. Evening of 6 April 2000, in Europe and north American continent, there aurora picture. Earth's northern hemisphere in general do not see the Aurora area, even in the southern U.S. state of Florida and central and southern Germany, there have been large areas of Aurora. Night, red, blue, green and white light filled the night sky, the scene was spectacular. Although this is a rare case of a blessing, but in the past suddenly appeared in the sky plain brilliant colors, in many areas also caused a panic. According to the German long wave Hong Tianwen observatory station Kaminsky said that night the police station north of the German Rhineland and the astronomical observatory of the phone calls, and some people even suspect gas leak incident has occurred. The aurora phenomenon is far from the 160-km altitude ACE spacecraft observing the sun, find, and issued the notice. In Beijing at 0:30 on April 7, found that an ACE spacecraft carrying a strong solar wind of charged particles from passing next to it, and the sudden acceleration of the solar wind speed from 375 kilometers per second up to 600 kilometers per second , an hour later, it shares the outer edge of the solar wind reaches the Earth's atmosphere, as we showed a rare good fortune of God workers. The polar aurora is additional information unique to the region of an atmospheric light phenomena. Aurora in the myths and legends of East and West have left a beautiful figure, development of modern science have enabled humans to a rational look at Aurora, its a scientific explanation. Over the years, Aurora's genetic mechanism has not been satisfactorily explained. For a long period of time, it was believed that the aurora may be formed by the following three reasons. Aurora is a perception that the fire ignited outside the Earth, because the Arctic region near the edge of the earth, they are able to see this fire. Another view was that, after Aurora was setting is red, the transmission out of the reflective glow. There is a perception that the polar ice-rich, they absorb sunlight during the day, store up, to be released at night, became the aurora. In short, different opinions, no certain theory. Danish photographer until 20

early morning shooting on August 4 to Aurora landscape

In the 1960s, the ground observations and satellite and rocket data to detect the combination of research, was gradually formed the physical nature of the aurora description. It is now recognized, one with the Earth's upper atmosphere aurora and geomagnetic field of large-scale interactions, on the other hand with the sun out of the eruption on high-speed stream of charged particles, such particles commonly referred to as the solar wind. Thus, an indispensable condition for the formation of the aurora is the atmosphere, magnetic field and solar wind, are indispensable. These three conditions have other planets of the solar system, such as Jupiter and Mercury, their surroundings, will produce the aurora, which has been proved by the fact that actual observations. To the magnetic field distribution around the Earth, the solar wind to be wrapped to form a wooden club-like gel, it's scientific name is called the magnetosphere. In order to visualize, we are playing this analogy. Magnetosphere can be seen with a huge TV picture tube, it enters the upper atmosphere of the solar wind particles flow converging beam, focused to the geomagnetic poles, the polar regions the atmosphere is a CRT screen, Aurora is moving on the TV screen image. However, there is not the TV screen is 18 inches or 24 inches, but the diameter of 4000 km polar upper atmosphere. Typically, the audience on the ground, somewhere only see the screen l/50. In the television picture tube, the electron beam hit the TV screen, because the screen is coated with luminous material, it will emit light, displayed as an image.
