Measurements taken by the Solar Wind Around Pluto (SWAP) instrument aboard NASA`s New Horizons spacecraft are providing important new insights from some of the farthest reaches of space ever explored. In a paper recently published in the Astrophysical Journal, a team led by Southwest Research Institute shows how the solar wind-the supersonic stream of charged particles blown out by the Sun-evolves at increasing distances from the Sun.
