The heliosphere is the big magnetic bubble in space carved out by the solar wind. It defines the sphere of influence of the Sun and extends well beyond the furthest fringes of the Solar System. The ESA/NASA Ulysses mission has studied it in four dimensions (space and time) for more than 17.5 years.
