Since 1977, the probe “Voyager 1″ is on the way. Meanwhile, it is unimaginable 18 billion kilometers from the Sun, and thus the farthest scouts of mankind. Only what they explored there in the distant worlds?
probe “Voyager 1″ approaches the very edge of the solar system. “This strange, last region before interstellar space now reaches into our focus, thanks to ‘Voyager 1′, the furthest scouts of humanity”, in charge of the spacecraft scientists declared at the California Institute of Technology in Pasadena, Ed Stone. “Voyager 1″ since 1977 is underway and still sends data back to the U.S. space agency NASA.
On Thursday, three articles in the journal “Science” published in which the region is described in the “Voyager 1″ on 25 August 2012 arrived. By researchers as a “magnetic highway” designated region is about 18 billion kilometers from the sun. This is equivalent to 122 times the distance of Earth to the Sun. Your name comes along that can move smoothly in and out of the heliosphere out to their charged particles along magnetic field lines.
start in September 1977
“Voyager 1″ was launched in September 1977, a few weeks after the partner probe “Voyager 2″ to study the planet Jupiter and Saturn. According to the researchers, it may take months or years before the probe reaches the interstellar medium outside the heliosphere. The heliosphere is the interplanetary space where the solar wind are felt. According to the articles adopted by the entry of “Voyager” in the region of the “magnetic highway” the number of particles within 24 hours abruptly.

In one day have the magnetic field in this region suddenly doubled and was “extremely smooth” become, wrote lead author Leonard Burlaga. “But there was no significant change in the direction of the magnetic field, we still see the outgoing field lines of the sun.” For the first time since the launch of “Voyager” the researchers to measure cosmic rays were therefore able emanating from dying stars.
The twin probe “Voyager 1 and 2″ passed Jupiter in 1979, Saturn in 1980 before they reached Uranus in 1986 and Neptune in 1989.
