NASA scientists announced on Monday, November 19, that Voyager 2, an unmanned space probe launched in 1977 and designed for a five-year mission, has continued its journey billions of kilometers from Earth and has become the second man-made object to leave the solar system and enter interstellar space. According to Reuters, NASA stated that data sent from the probe indicates that Voyager 2 crossed the heliosphere boundary, the area dominated by solar winds or particles emitted by the sun, on November 5. The heliosphere boundary is located 18 billion kilometers from Earth. In this region of space, hot solar winds collide with a collection of celestial bodies located between the stars of the Milky Way galaxy. Ed Stone, one of the scientists involved in the Voyager space project, said at a press conference, 'This is another exciting milestone in Voyager's 41-year journey, which has been exploring the planets of the solar system and is now continuing its journey into the heliosphere and interstellar space.' Voyager 1, another probe from this project, entered interstellar space in 2012. The exploratory equipment of Voyager 2, known as the 'Plasma Science Experiment,' is capable of examining the coordinates of this region of space. Reuters adds that the Voyager exploratory program was originally designed for a five-year period to study the planets Jupiter and Saturn. However, with the continued operation of the two Voyager probes, they were able to complete exploratory missions around Uranus and Neptune, the farthest planets in the solar system. Both probes are equipped with a phonograph device that records greetings in various languages, aimed at communicating with extraterrestrial beings they may encounter during their mission. Nicola Fox, director of NASA's heliophysics division, stated, 'We are often asked if this is the end of the Voyager mission. I don't think so at all. I believe this is a new era in solar physics. It is a great fortune that two brave probes have been able to exit the heliosphere and continue their explorations beyond the boundaries of the solar system.'
