At the same time a stream of particles blowing out from the sun the solar wind inflates a bubble of plasma around the solar system called the heliosphere Astronomers have assumed long that the sun's motion through the galaxy squashes
and spreads the heliosphere into a bullet shape with an extended tail at the back (see image).
when charged particles from the solar wind collide with other charged particles in the outer heliosphere Some of these neutral atoms are bounced back towards us.
The magnetic field of the heliosphere protects us from the bulk of these galactic high-energy particles. But some manage to impinge on our solar system
