"Voyager 1" yet to be released into the interstellar medium


21/03/2013

Transferred from NASA interplanetary probe "Voyager 1" data on sudden changes in the properties of cosmic rays do not allow experts to speak confidently about the output device of the solar system and its appearance in interstellar space, said Vladislav Izmodenov head of the laboratory of the Institute of Space Research.

The American Geophysical Union (AGU) previously reported that the "Voyager 1" has already left the heliosphere - a layer consisting of the solar wind and the solar magnetic field, that is out of our planetary system. According to the information scientists probe recorded August 25, 2012 in the cosmic-rays of different origin sudden changes, in particular, sharply reduced the proportion of particles coming from the sun and doubled the intensity of galactic cosmic rays.

The representative of the Russian Academy of Sciences said that so far there is no sign of the interstellar magnetic field, showing the "exit". - "Despite the fact that the magnetic field is increased to three or four times, it still has the same orientation as in the heliosphere. Though, in fact, it should certainly change the orientation. So you can not yet say that" gelioklif "( boundary fluxes of energetic particles) is the heliopause (the boundary of the heliosphere), "- said Izmodenov.

Meanwhile, representatives from NASA application for withdrawal "Voyager" in the interstellar medium is also considered premature.

"According to the research team of the project" Voyager "," Voyager 1 "solar system is not left in the interstellar medium has not left. Group reported that in December 2012," Voyager "was released in a new region, where the properties of the particles greatly altered "- said Edward Stone, one of the scientists of the project.

"The last critical feature of the device penetration into interstellar space is a change in the direction of the magnetic field, and as long as the change in this direction have not been," - he said.
