"That was about three months before Voyager 1 crossed the heliopause and entered interstellar space", said NASA. The probe's Low-Energy Charged Particle instrument has detected a similar increase in higher-energy cosmic rays.
Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.
Once Voyager 2 exits the heliosphere, it would be the second human-made space probe to reach the interstellar space after Voyager 1 which managed to exit our Solar System in August 2012.
"We're witnessing a reform in the environment nearby Voyager 2, there's no hesitation about that, we're exertive to grasp a lot in the coming months, but we still don't know when we'll come to the heliopause". So, up until "Voyager 2" crosses heliopause, it will be impossible to say with certainty where it is in relation to her he is. Throughout the Solar System, the wind from the Sun exerts an outward pressure.
There are two instruments on board the spacecraft, which noticed at the end of August a difference in how the probe was hit by cosmic rays.
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 the Chronicle.info with reference to UKRINFORM.
"A development in cosmic rays is that its outside our solar system" NASA Reported In May 2012, Voyager 1 experienced an addition in the frequency of cosmic rays akin to what Voyager 2 is now disclosing.
On one side is the heliosphere, the Solar System's bubble carved out by the solar wind. This excess could have been a sign that the spacecraft is about to cross the heliopause and enter interstellar space.
The team behind Voyager 2 knows that the spacecraft is now nearly 11 billion miles (17.7 billion kilometers) away from Earth. The information they have returned to Earth has revolutionized the science of planetary astronomy, helping to resolve key questions while raising intriguing new ones about the origin and evolution of the planets in the solar system. However, this solar wind wanes every 11 years in accordance with the solar cycle.
