*Inside the heliosphere there is a constant storm of heated and charged particles that come from the Sun.
*The heliosphere bubble shelters life on Earth from destructive cosmic rays the come from supernovas.
*It’s the region of space that the Sun commands; its sphere of influence and the extent of the solar wind—charged particles spewed-out by the Sun–that extends far past the orbits of the planets.
*At the edges of the heliosphere is where the solar wind meets the interstellar wind.
*It casts a magnetic force field around all the planets, deflecting charged particles that would otherwise get into the solar system ... and destroy DNA. Or mutate it, which could have created us.
