Then how Pooh can survive? Voyagers found the answer to this question. 'Data from the Voyager, show that "Pooh" magnetization is much stronger than previously thought – the force of the magnetic field is in the range from 4 to 5 mikrogauss' – says Ofer (Opher). 'Such a magnetic field can provide additional pressure that can oppose the destruction. " Two nasa space research probes – Voyager – flying in the direction of the borders and beyond the solar system over 30 years. Now they have crossed the orbit of the planet Pluto and is on the verge entry into interstellar space – but not yet entered it. 'Voyagers are currently not yet reached the Local Pooh' – says Ofer (Opher). – 'But they are close and can "feel", how does the cloud when they approached.
" "Pooh" is held exactly on the edge of the solar system magnetic field of the sun and blown by the solar wind in the magnetic bubble width of more than 10 billion miles. Called 'the heliosphere', this is a bubble shield, which helps protect all the objects in the solar system from galactic cosmic rays and interstellar clouds. Both the Voyager are in the distal layer of the heliosphere or '', where the solar wind slows down pressure of the interstellar gas. Voyager 1 entered the gelioobolochku in December 2004, after almost 3 years, in August 2007, Voyager 2 repeated his way. These intersections become key to the discovery made Ofer and his et al. Dimensions of the heliosphere are determined by the law of equilibrium of forces: the solar wind blows a bubble from the inside, while the Local Fluff squeezes it out.
Penetration of Voyagers in gelioobolochku allowed to establish approximate dimensions of the heliosphere and, accordingly, the pressure exerted by the Local Pooh. Part of this pressure is due to the magnetic field and corresponds to 5 mikrogaussam, as a group Ofer (Opher) reported in the journal Nature. The fact that Pooh is strongly magnetized, means that in the galactic environment may also be other clouds. Over time, the solar system collide with some of them, and their strong magnetic fields can compress heliosphere an even greater extent than it does now. Additional compression may allow more cosmic rays penetrate into the solar system that may have an impact on the Earth's climate and the ability of astronauts to perform safe flight in space. On the other hand, the astronauts would not need to fly so far, because interstellar space would be to us a lot closer than ever. These events unfolded to a time scale extending from tens to hundreds of thousands of years, depending on how long it takes the solar system to move from one cloud to another. 'What is interesting time may await us in the future ', – exclaims Ofer.
