Scientists 40 years struggled over a riddle about strange indignations magnetic fields in outer space and finally her guessed it. This was reported by the information publication Phys.org.
Scientists examined data obtained by twelve satellites, which previously recorded disturbances in local magnetic fields. These disturbances were caused by tiny particles that tolerates the solar wind. This dust cloud has entered the magnetosheath of our planet located between the head shock wave and magnetopause.
About forty years ago, near Venus, scientists discovered a strange twelve-hour oscillation of the magnetic field. Later researchers repeatedly observed this phenomenon, but the explanation for it was never found. Astronomers have suggested that the cloud is to blame magnetized dust resulting from collisions of meteorites and comets.
Having developed a special model, scientists came to the conclusion that dust ionized by sunlight and then gaining speed under the influence of the solar wind. When does this dust get in the magnetosheath, then the solar wind slows down, but larger particles continue to move in space at the same speed. As a result, dust attracts charged particles to magnetosheath.
