The NASA probe has reached the edge of the Solar system
The probe of the American space Agency have recorded increase of the concentration of cosmic rays produced another solar system, which means that he approached the border of interstellar space, reports citing .
This is stated on the website of the jet propulsion Laboratory, California Institute of technology NASA.
“NASA’s Voyager-2, are now on the path to interstellar space, has detected an increase in cosmic rays that originate from outside our solar system,” the article says.
Launched in 1977, the probe is at a distance of 17.7 billion kilometers from Earth, that the 118 times the distance between Earth and the Sun. Since 2007, the probe passes through the top layer of the heliosphere – the giant “bubble” around the Sun and the planets that are affected by its magnetic field. The researchers are watching to see how the device will reach the outer boundary of the heliosphere, known as heliopause. Voyager 2 would then become an ideal object, created by man, after Voyager 1, which was able to enter interstellar space.
Since the end of August this year, the instrument probe has registered a 5% increase in the level of cosmic rays in comparison with the beginning of the month. At the same time the unit of measurement level nizkozatratnyh particles has found a similar increase in cosmic rays with higher energy.
In may 2012, a similar increase in the level of cosmic rays, which are born outside our Solar system, Voyager 1 found. Three months after that, he came out in interstellar space.
However, a team of scientists indicate that the probes were in different areas of the heliopause and that the solar activity varies over 11 year cycle. This means that Voyager 2 may reach interstellar space sooner or later than its predecessor.
Spacecraft the Voyager series was created by jet propulsion Laboratory in Pasadena, California. The mission Voyager is part of the Observatory system geleophysic NASA.
