The heliopause is the final known boundary between the heliosphere and the interstellar space that is filled with material, especially plasma, not from the Earth's own star, the Sun, but from other stars. [46]

heliopause, boundary of the heliosphere, the spherical region around the Sun that is filled with solar magnetic fields and the outward-moving solar wind consisting of protons and electrons.

Heliopause (astronomy), the theoretical boundary where the Sun's solar wind is stopped by the interstellar medium.

2024年8月22日 · NASA studies the heliosphere to better understand the fundamental physics of the space surrounding us – which, in turn, provides information regarding space throughout the rest of the universe, as well as regarding what makes planets habitable.

2022年5月4日 · The heliopause is the point where the influence of our solar system balances against that of the interstellar medium along the edge of the heliosphere, which is a bubble created by the clouds of...

Our Sun, along with its heliosphere, moves through the interstellar medium (ISM). The boundary between the heliosphere and the interstellar medium is called the heliopause. The heliopause is the edge of the solar system based on the influence of the …

2021年5月25日 · Scientists define the beginning of interstellar space as the place where the Sun’s constant flow of material and magnetic field stop affecting its surroundings. This place is called the heliopause. It marks the end of a region created by our Sun that is called the heliosphere.
