The Voyager 1 spacecraft, the farthest man-made object travelling in space from earth, has indeed left the heliopsphere, the bubble that surrounds our solar system, and has entered interstellar space.
In 30,000 years, Voyager 1 will leave the Oort Cloud, the outer boundary of the solar system. And in 40,000 years, it will be closer to the closest star than our sun. Voyager is indeed going where no man or machine has gone before.
