Sun-Earth Day 2008: Space Weather Around the World

IMAGE GALLERY

Figure 3:  This is a diagram that shows the different parts of the heliosphere. As the Sun moves through the interstellar medium, the material around it is 'pushed' out of the way by the solar wind, which forms the heliosphere. Each part of the heliosphere has a different name, as indicated on the diagram: the bow shock, heliopause, heliosheath, termination shock, and the heliotail. (Courtesy: NASA-IBEX).
