IMAGING OF THE INTERSTELLAR GAS FLOW FOR DIFFERENT SPECIES
AND NECESSARY INSTRUMENTAL TECHNIQUES

Presented at Sun-Earth Connections "Roadmap" Workshop
2-3 March, 1999; Greenbelt, MD


WE WANT TO UNDERSTAND:

  • The boundary of our heliosphere and its interaction with its neighborhood --
    Interaction typical for "Astrospheres" around other stars;
  • Our local environment in the galaxy;
  • The evolution of the galaxy and the universe.
