Heliosphere. Artwork of the heliosphere and its features. The heliosphere is a space in the interstellar medium (orange) formed by the Sun (centre right) and its solar wind. The shape of the heliosphere is formed by the direction of travel of the Sun through the interstellar medium, here from right to left. The features of the heliosphere include the bow shock (orange, centre), the magnetic bubbles (red, centre) of the heliosheath which marks the heliopause, the termination shock (light blue), and magnetic field lines (red and blue). This new view (2011) shows the heliopause as a porous structure. It was previously thought to be continuous.
