'We believe that the tape is a reflection' – said Hirihusen Jakob (Jacob ), a visiting scholar in the field of heliophysics, nasa, the University in Huntsville, Alabama – 'This is where the solar wind particles, ejected into interstellar space, are reflected back into the solar system galactic magnetic field. " Hirihusen () – the main author of the article, in which the results of an investigation and which was published in the issue "Letters of the Astrophysical Journal on January 10, (Astrophysical Journal Letters). 'This is a very important discovery ", – said Eric Posner (Arik Posner), Fellow Programme Researcher isn Borders (IBEX) at nasa headquarters. "Interstellar space located just outside the boundary of the solar system, is largely unexplored area. Now we know that there may be strong, well-organized magnetic field, located right on the doorstep of our Solar System '.
Data obtained using the apparatus of ibex, in excellent agreement with recent results obtained with the Voyager interstellar spacecraft (Voyager). Voyagers 1 and 2 are now just at the fringe Solar system, and they also "feel" strong * magnetism nearby. However, measurements made by Voyager instruments are relatively narrow (local) character. Research unit ibex provides information 'in broadly. " Tape on which he observes, is big enough and stretched nearly the entire sky, and this suggests that the magnetic field beyond the tape, should be equally great. Although the maps tape (See below) is a luminous body, in fact, the tape does not emit light. Instead, it declares itself by particles called energetic neutral atoms' (ENA) – mainly hydrogen atoms.
Tape emits these particles, which ibex catches, moving in an orbit around the Earth. The reflection process, postulated Hirihusenom and other sponsors, is somewhat difficult to understand, and include multiple reaction 'charge exchange' between protons and hydrogen atoms. The result of this process, however, is simple. Particles that make up the solar wind, flying beyond the solar system and left about a distance of 100 astronomical units (about 15 billion kilometers), come into contact with the interstellar magnetic field. Magnetic forces detain "runaway" of the particle and throw them back whence they came. 'If the mechanism process of reflection, really, is this – and agree not all – some form of tape will tell us much about the orientation of the magnetic field lines in our corner of the Milky Way '- said Hirihusen (). And this field, can be our future depends. The solar system now passes through the Milky Way, abounding in cosmic rays and interstellar clouds. The magnetic field of our own Sun, vented solar wind in a bubble, called the heliosphere, largely protects us from these dangerous things. However, the bubble itself quite vulnerable and exposed to external fields. Strong magnetic field, located just behind outside the solar system can compress the heliosphere and interact with it in an unknown manner. No one is safe can not say whether this will increase our natural defenses, or weaken it? Spacecraft ibex will closely monitor the tape in the coming months and years ", – says Posner. 'We can observe the shape change of tape – and it will show us the way we interact with our galaxy there, at a distance ' It turns out that we can learn a lot by looking in the mirror.
