termination shock

n.
An outer region of the solar system, about 8 billion miles (12.8 billion kilometers) from the Sun, where a standing shock wave is generated as the solar wind, encountering the interstellar medium, slows to subsonic speeds.

These materials interact at the heliospheres edge to create a region known as the inner heliosheath, bounded on the inside by the termination shock which is more than twice as far from us as the orbit of Pluto and on the outside by the heliopause, the boundary between the solar wind and the comparatively dense interstellar medium.

Among specific topics are cosmic magnetic fields from torsion modes and massive photon inflation, the numerical treatment of dust diffusion in dusty proto-planetary disks, time-dependent processes in the sheath between the heliospheric termination shock and the heliopause, energetic particle transport with stochastic differential equations: general methods and the extension to anomalous diffusion regimes, building a numerical relativistic non-ideal magnetohydrodynamics code for astrophysical applications, and a new two-moment scheme with algebraic closure for energy-dependent multi-flavor neutrino transport in supernovae.

It wasn't until December 2004, when 94 astronomical units from the Sun (83/4 billion miles), that Voyager 1 passed through the termination shock, where the solar particle flow becomes subsonic, and made the first direct measurements of the heliosheath, a transition region between the shock and the interstellar gas.
