Beyond the orbit of Pluto, a small spacecraft named New Horizons is drawing closer to the edge of the sun's dominion — a boundary where the solar wind, having traveled billions of miles, finally surrenders to the pressure of interstellar space. Researchers at Southwest Research Institute have refined their models enough to estimate that this crossing, known as the termination shock, will occur somewhere between 2029 and 2040, depending on the sun's own rhythms of activity. It is a moment humanity has approached only twice before, with the Voyager probes, and it asks an ancient question in a ne
