Where is the heliosphere’s boundary called the heliopause located?
Quick Answer
The heliopause is the outer boundary of the Sun’s influence, far beyond the planets. Voyager 1 crossed it in 2012 and Voyager 2 in 2018.
The Full Story
The heliopause is the boundary where the solar wind is stopped by the interstellar medium. It lies far beyond the planets, marking the edge of the Sun’s protective bubble called the heliosphere. Voyager 1 crossed it in 2012, and Voyager 2 followed in 2018 from a different direction. These crossings gave humanity its first direct measurements of interstellar space.
