Voyagers’ readings yield new clues about the solar system’s structure

The video discusses the boundary region where the sun's influence ends and interstellar space begins, known as the heliosphere. It highlights Voyager 2's findings of a sharp difference in magnetic particles and plasma density at the heliopause, suggesting it is thinner and less affected by solar cycles than previously thought. The sun creates the heliosphere by emitting solar wind, which interacts with interstellar winds, forming a distinct boundary.
