interstellar space
Void between stars
Interstellar space is the vast expanse between star systems—the regions of a galaxy not dominated by any particular star's influence.
Our solar system ends where interstellar space begins, at the boundary where the sun's solar wind gives way to the general medium of the galaxy.
Voyager 1 became the first human-made object to enter interstellar space.
