The Voyager 1 spacecraft is 11 billion miles from the sun. And every minute, it gets 636 miles closer to its destination: the frontier of interstellar space.
The craft is currently in what NASA calls, not undramatically, "the boundary between the solar wind from the Sun and the interstellar wind from death-explosions of other stars," an area that astrophysicists also call, less dramatically, a stagnation layer.
