heliopause

[′hē·lē·ə‚pȯz]
(astronomy)
A shock front about 50 astronomical units from the sun, where the thermal pressure of the interstellar gas which surrounds the solar system overcomes the pressure of the solar wind, which is mostly ram pressure due to its high-velocity flow.

Some solar wind protons that flow out from the sun to this boundary region will gain an electron, making them neutral and allowing them to cross the heliopause. Once in the interstellar medium, they can lose that electron again, making them gyrate around the interstellar magnetic field.
The study shows that the initial direction of the magnetic field observed by Voyager 1 is deflected by the heliopause, like an elastic cord wrapped around a beach ball.
This second boundary is called the heliopause. The third boundary was thought to be the bow shock, formed as the heliosphere plowed its way through the local galactic cloud the same way a supersonic jet pushes aside the air as it moves.
The Sun's hot corona continuously expands in space creating the solar wind, a stream of charged particles that extend to the heliopause at roughly 100 astronomical units.
It travels outward, as the solar wind after its ecstatic burst travels outward past the planets and through the cloud of comets, carrying electric and magnetic fields to the heliopause, and meets the cosmic rays and magnetic field of the galaxy.

The two are in search of the heliopause boundary in addition to the outer limits of the sun's magnetic field and the outward flow of solar wind, (https://www.jpl.nasa.gov/voyager/mission/interstellar-mission/) according to NASA .
