Scientists have dubbed this region the "magnetic highway" and it's the last stop before interstellar space, or the space between stars.
The findings were presented Monday at a meeting of the American Geophysical Union meeting in San Francisco.
Voyager 1 and its twin Voyager 2 launched 35 years ago on a tour of the outer planets. Afterward, both spacecraft continued to hurtle toward the fringes of the solar system.
Mission chief scientist Ed Stone says it's unknown when Voyager 1 will finally break through to interstellar space. Once that happens, it'll be the first manmade object to leave the solar system.
