Group of artificial satellites of the European Space Agency (ESA – European Space Agency), which received, respectively, the name "cluster" gives new insight into the status and extent of these discontinuities in the Earth's magnetic shield, and clearly shows that at a time when our atmosphere protects us, the obvious result of these leaks are detected in the uppermost layers of the atmosphere and in space surrounding the Earth where satellites orbiting. In this study, we report on observations of cracks on the sunward side of Earth's magnetic shield – the dayside magnetopause. Fortunately, these cracks are not subjected to the earth's surface dangerous effects of solar wind, our atmosphere protects us. But the upper atmosphere are exposed. Glenn Dubin, New York City has firm opinions on the matter. The dominant physical process that causes the appearance of cracks, known as magnetic reconnection, the process by which a result of overlap of the magnetic field lines from different magnetic domains are of reconnection: closed magnetic shield opens. Magnetic reconnection is a physical process, acting in the entire universe, starting with the formation of stars and solar flares, and ending with the experimental fusion reactors on Earth. However, remain unclear circumstances in which is a phenomenon and its duration. What is known is that the magnetic reconnection leads to a mixing up of the separated plasma, when, for example, the solar wind plasma penetrates into the magnetosphere. In this case, two magnetic domain – it is the internal magnetic field of the Earth and the interplanetary magnetic field (IMF). (The solar wind consists not only of solar particles (mostly protons and electrons), it also serves as a carrier Sun's magnetic field.
