Record 2 2022-10-18

English

Subject field(s)
  • The Sun (Astronomy)
CONT

... the heliopause... marks the end of a region created by our Sun that is called the heliosphere. The Sun creates this heliosphere by sending a constant flow of particles and a magnetic field out into space at over 670, 000 miles per hour.

Domaine(s)
  • Soleil (Astronomie)
CONT

Un peu comme l'huile ne se mélange pas à l'eau, le vent solaire et le milieu interstellaire ne sont pas tout à fait miscibles, le vent solaire crée donc une bulle dans le milieu interstellaire baptisée héliosphère. [...] l'héliosphère agit comme un bouclier pour tout ce qu'elle renferme et protège notamment notre fragile ADN des radiations les plus intenses de la galaxie. La limite extérieure de l'héliosphère porte le nom d'héliopause et marque le début de l'espace interstellaire.

Subject field(s)
  • Astrophysics and Cosmography
  • Space Physics
CONT

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.

La limite extérieure de l'héliosphère porte le nom d'héliopause et marque le début de l'espace interstellaire. La compréhension de cette limite peut nous aider à mieux cerner le voyage effectué par le Soleil à travers la galaxie, ce qui en retour nous permettra d'en apprendre plus sur la situation des autres étoiles dispersées dans l'univers.

English

Subject field(s)
  • The Sun (Astronomy)
DEF

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.

Record 5 2003-03-17

English

Subject field(s)
  • Space Physics
CONT

The Sun emits a steady flow of electrically-charged particles called the solar wind. As the solar wind expands supersonically into space, it creates a magnetized bubble around the Sun--the heliosphere. Eventually, the solar wind runs into the electrically-charged particles and magnetic field in the interstellar gas. The solar wind abruptly slows down from supersonic to subsonic speed, creating a termination shock. Before both spacecraft travel beyond the heliopause into interstellar space, they must pass through that shockwave.
