"Voyager-2" became the second object created by man in the history of humanity, in interstellar space. NASA experts have announced that the device was tracking its "twin" – "Voyager-1" – was surpassing the heliosphere, informs UkrMedia.
The Voyager-2 probe was launched to study the solar system in 1977. The aircraft was able to move closer to the four giant planets and explore them, then headed to the periphery of the solar system. It was planned that the probe would only work in a maximum of five years, but in August 2018, its mission marked its 41st anniversary. Now the device is at a distance of nearly 120 astronomical units from the Earth (the most distant hand-made object is the Voyager 1, the distance at which are almost 145 astronomical units).
Since 2007, the probe was in the outer layer of the heliosphere – the area of space. , where the main component of the environment is the solar wind and the magnetic fields of the Sun. At the edge of the heliosphere, called heliopause, the solar wind speed drops to almost zero. Even more, at a distance of more than 200 astronomical units from the Sun, is the main shock wave on which particles of the interstellar wind begin to inhibit.
Since the end of August, CRS detectors and LecP (Low-Energy Charged Particles) low-energy particles aboard the probe have begun to record an increase in the energy of the charged charged particles. In May 2012, Voyager 1 detected similar changes in cosmic ray parameters. This was about three months before the camera entered interstellar space. The most important role in the evolution of the device from the heliosphere resides in the data obtained by the PLS tool (Plasma Science Experiment), which determines the speed, the density , the temperature and pressure of the surrounding plasma medium, mainly consisting of solar wind particles. On November 5, the tool recorded a sharp decrease in the speed of the solar wind particles and, in the future, showed no sign of presence of a near sun flow Voyager-2, indicating that the aircraft had actually left the heliosphere.
Despite the fact that the device has gone beyond the heliosphere, this does not mean that qu & # 39; 39 He left the solar system, whose boundary is located outside the outer edge of the Oort cloud, on about one hundred thousand astronomical units of the Sun. "Voyager-2" takes about three hundred years to reach the Oort cloud, and maybe about 30,000 years to fly over it.
