For the second time in history, a human-made object has reached the interstellar space. The Voyager 2 space probe came out of the heliosphere, a space filled with particles from the Sun and in which the magnetic field of our star does not work. Based on data from the space probe, mission scientists have determined that it has crossed the outer edge of the heliosphere, on November 5, 2018. At this boundary, heliopuses, a hot solar wind confronts a cold, thick interstellar medium. His twin, Vojager 1, crossed this border in 2012. Voyager 2 is now just over 18 billion kilometers from Earth. Mission operators continue to communicate with Voyager 2. The information is moving at the speed of light and traveling about 16.5 hours from the space probe to Earth. Light from the Sun to Earth travels eight minutes. The most significant proof of the outbreak of Voyager 2 from the heliosphere comes from the Plasma Science Experiment (PLS), an instrument that stopped working on Voyager 1 in 1980, much before the probe crossed the heliopause. Until recently, the space around Voyager 2 was predominantly filled with plasma from the Sun. This outflow, called the solar wind, creates a bubble, heliosphere, which includes solar system planets. PLS uses electric plasma power to detect speed, density, temperature, pressure and flux of solar wind. PLS on Voyager 2 recorded a sudden drop in the speed of solar wind particles on November 5th. From that date, the instrument did not notice any solar energy flow in the Voyager 2 environment, which keeps the mission scientists in the belief that the probe left the heliosphere. In addition to plasma data, Voyager's scientific team has evidence from three instruments that detect cosmic rays, energy of charged particles, and a magnetic field, suggesting that Voyager 2 transmitted the heliopause. Team members continue to study data to get a clearer picture of the environment through which Voyager 2 travels.
