The mystery of the universe Aurora.

<P Align=center> </ P> <P> Technology Channel (tech.) message: the earth in the sparsely populated polar regions, often have bright magnificent, ever-changing band of light over the beautiful night sky. .In the Arctic, people call it "Northern Lights", appears in the Antarctic is called the "Southern Lights." .Aurora the polar regions, living in low latitude regions of the residents, it is difficult to see the it hosting the Games, which makes more show the mysterious Aurora. .</ P> <P> recently, Chinese space scientists Jin-Bin Cao, who with four satellite observation data, for the first time opened the source of the mystery of the aurora, the European Space Agency website home page to "CLUSTER Constellation reveal the mystery of Earth's aurora ."in the title, a comprehensive introduction to the important results. .</ P> <P> Eskimos believe that Aurora is the spirits to guide the dead souls to heaven's torch </ P> <P> than 2,000 years, China has emerged on the auroral records, and in ancient Japan, Greece .Rome also has a text description on the Aurora. .In some national imagination, the Aurora was given the lofty meaning, such as the Eskimos to recognize that it is the spirits to guide the dead souls to heaven's torch. .As scientific knowledge of the poor, in a very long time, people close to the absurd interpretation of the nature Aurora. .</ P> <P> a perception that the aurora is the fire ignited outside the earth because the earth near the edge of the Arctic, they are able to see this fire. .Another view is that the aurora is at Xi Chen Xi after 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, it became the aurora. .</ P> <P> into the 19th century, scientists tried to understand from a scientific point of view the principle of generating the aurora. .Some studies that the aurora is visible from the solar wind (the sun continuously radiates to the space of stable particles) produced by collision with atmospheric atoms, this view became mainstream causes auroras were various types of .continue to quote the popular science books. .</ P> <P> Later, however, space physicists found by observing the solar wind collide with atmospheric atoms can be generated after the Aurora, but the Aurora is extremely weak, and its main settlement area in the daytime side of naked eye can not see the general .not people see the source of the aurora. .</ P> <P> 20 century, the late 80s, the United States and Europe but also in earth and space scientists found that the magnetic tail of charged particles to the earth in an outbreak of high-speed stream. .However, these high-speed particles of how to produce, whether there is a link the formation of the aurora, has been outstanding. .</ P> <P> Substorm launch high-speed particles collide with atmospheric atoms produced is the real cause of the aurora </ P> <P> China Space Science Institute Dr. Cao Jinbin invited to ESA scientists CLUSTER program of cooperation .. .Magnetosphere in the detection of the major space program, there are four satellites in orbit to collect the same data. .Jin-Bin Cao to the original single satellite in space is only a single point, if the use of multi-satellite observations, are expected to learn more information about the aurora. .</ P> <P> depth study, Jin-Bin Cao's team has been convincing data: 95% of the magnetospheric substorm launch high-speed particles, the north and south latitude 65 degrees to 70 degrees with oval-shaped regions .aurora appeared. .Can be sure that these high-speed particles collide with atmospheric atoms produce the aurora is the real reason. .</ P> <P> According to Jin-Bin Cao introduced the so-called "magnetospheric substorm" is the enormous energy stored in Earth's magnetosphere and the sudden release of transient events, occurring about 3-4 times a day. .Each substorm energy release is roughly equivalent to the energy of a moderate earthquake, in addition to the space environment in Earth's polar regions of the dramatic changes, also strongly stimulate the Earth's ionosphere disturbances, the reception of GPS navigation signals, as well as between the satellite and the Earth .communications. .Therefore, this research not only describes the causes of auroras, space weather research and forecast for also of great significance, and to protect the safety of aircraft and crew, the safe use of such satellites will play an important role. .</ P> </ p>.
