Voyager 2 in interstellar space

since its launch in 1977, the Voyager 2 spacecraft has already travelled 18 billion km. The data has shown that he left the heliosphere a year ago, this protective bubble formed by the Sun’s magnetic field, which envelops the planets of the solar system, and entered the mysterious interstellar space. The data from the crossing of the heliosphere border have been analyzed and the first results have been published.
