The phenomenon of aurora borealis

This phenomenon is also called as the polar dawn or northern lights, which is one of the most fascinating phenomena picturesque that Tbherna nature at all!These deals have been amazing optical mystery baffles scientists for so long that NASA was able to solve this mystery using five satellites to discover that the reason is as follows:Those dazzling colors result from the interaction of charged particles powered portable with the solar wind with gases in the upper layers of the atmosphere.What is the source of these particles? .. It is the sun that is the source of energy in the solar system and surrounded by fields of energy is growing gradually to reach the peak of its cycle every 11 years are given stream blistering of charged particles, where it appears on the surface of the sun is known spots solar and is the brand's clear solar activity, accompanied these spots explosions on the surface of the sun know Balentoat, is responsible for sending charged atomic particles (protons, electrons, hydrogen, helium .....) and also rays (Sunni, gamma, ultraviolet) these particles withstand wind surging rapidly to reach the parties to the solar system even hit the ground directly to these particles to find life on Earth as we know it, what protects the earth?He atmospheric magnetic surrounded by land, the land is a piece of magnetic high pole north of another southern two lines of magnetic forces that are moving from the South Pole toward the North Pole, ending with a colon poles Amonatisien, as a result of the solar wind coming compressed magnetic field lines sharply in terms of the sun and stretching direction the opposite problem trail magnetically long stretches hundreds of thousands of kilometers, and upon the arrival of charged particles located in the families of the magnetic field Vtbda movement spiral shape in two Qreptan the poles Amonatisien where hurtling electrons to the east and protons west around the earth problem Hzamat called belts Van Allen (relative to the physical world, the Allen) and the first belt is a small, nearby and consists of high-energy protons, the second largest and beyond, and consists of electrons and Brortunat the low energy. When intense solar activity Temtly belts Van Allen particles charged and as a result of the speed with which it is moving out of these particles, what to reach points poles continue to penetrate that region, which is the intersection of ionospheric land particulate Almnfelh of belts, so he gave us form oval around the magnetic pole is called scale auroral Valglaf ionic component of the various elements, particularly the (nitrogen. oxygen. hydrogen .....) interact with the particles coming Vtaathaj electrons into orbits higher energy and her return emerge colors bright radiant is aurora borealis and colors that we see blue and violet be responsible with them gas nitrogen, green and red oxygen gas, in addition to other colors are stunning, and in the case of increased solar activity extending auroral range toward the equator, where this can be seen in many scenic areas.There are activities and scientific research to predict the wind, solar like activities, weather forecasting, and held scientific project a huge position yoke and C with the participation of Britain, France, Germany, Norway, Sweden and Finland uses the antennas giant installed on panels large reception to collect information from the lights Arctic, line up those panels to cover larger space as possible in the sky and sends transmitters waves of high-frequency reflected when colliding electrons in ionospheric ground and rebounding part of those waves back to the ground radar to analyze how to respond gases to reach the stream of charged particles, are also collected some information from space probes orbiting the sun .Scientists are still hoping to take advantage of that information to understand space weather and phenomena Djiumgnatisah the better.
