The Voyager 1

New data of the solar system from the Voyager 1

The Voyager 1, which is the farthest artificial object in the Solar system, continues to deliver data on space surrounding it. Voyagers began studying of Earth and its vicinities in 1977. In 1979 and 1980 the device Voyager-1 passed by Jupiter and Saturn and went to interstellar space. The second probe Uranium and the Neptune visited and also goes to other stars. The first news that Voyager 1 left the Solar system, started arriving in 2003. At the end of summer of 2012 scientists started talking again that the border of Solar system is very close. Then the device sent astronomers very interesting data. However still it isn’t clear, whether he left the Solar system as indications of devices don’t correspond to ideas of physicists of space surrounding our planetary system. Our Solar system from external influence is protected by a solar wind. Area protected by the Sun conditionally calls a heliosphere. Speed of the particles which are thrown out by the atmosphere of our star, reaches one million kilometers per hour. The solar wind supports a magnetic field of the Sun which almost doesn’t pass harmful particles of space radiation in Solar system. Distribution of particles in this region of a space is not directed as particles from the massive blown-up stars of all Milky Way proceed. Now the Voyager 1 is at distance, in 120 million times exceeding distance from the Sun to Earth. The solar wind in this region considerably ceased, the particles dispersed by our star slowed down approximately in 1000 of times. One more circumstance which surprised astronomers: devices of the Voyager 1 register magnetic fields at the same level, as earlier. Physicists have no explanations for it as the galactic magnetic field has to settle down under a certain corner to solar (almost on 60 degrees). Then that the device still is under the influence of the Sun. In what place of the Solar system now there is a probe, scientists don’t know. Moreover, they also didn’t suspect about existence of a similar zone! So it is not clearly, how much time it will stay there:  a few months and, maybe, years. Radioactive fuel of the Voyager 1 will suffice approximately till 2020.  Approximately by 2025 the probe which initially prepared for five years of service, will finally fails and will lose touch with Earth.
