  • n. The area in which the outgoing solar wind and the incoming plasma from interstellar space meet. It is the boundary of our solar system.

  • n. the boundary marking the edge of the sun's influence; the boundary (roughly 100 AU from the sun) between the interplanetary medium and the interstellar medium; where the solar wind from the sun and the radiation from other stars meet

  • This border, called the heliopause, is a bubble-shaped boundary surrounding our solar system where the solar wind’s strength is no longer great enough to push back the wind of other stars.

  • The boundary where the pressure from the solar wind and the interstellar medium are at the same pressure, 16 billion kilometres from Earth, forms a giant bubble called the heliopause, and it's nothing like what scientists predicted it to be.

  • It slows as it begins to collide with the interstellar medium, and the point where the solar wind slows down is the termination shock; the point where the interstellar medium and solar wind pressures balance is called the heliopause; the point where the interstellar medium, traveling in the opposite direction, slows down as it collides with the heliosphere is the bow shock.

  • The finding would also suggest that IBEX is detecting the particles from both inside and outside the heliopause, which is the boundary region between the outer solar system and the local interstellar medium.
