  • 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.
