Heliosphere by Rob Rey -
The heliosphere is the region of space in which our solar systems found, where the solar wind (plasma) from our sun radiates outward and the magnetic field of the sun dominates space. This area ends well beyond Pluto. There, it meets the interstellar medium and it's boundary protects our solar system from most of the galactic cosmic rays coming from interstellar space.
