Figure 2:  This is a 'scary' diagram showing the regions of the heliosphere (click on image for larger view). There really isn't any fire-like cloud ramming into the heliosphere! It also shows the approximate locations of Voyagers 1 and 2. Voyager 1 is traveling faster and has crossed into the heliosheath. (Courtesy: NASA / Walt Feimer).
