Cosmic Rays and the Heliosphere [1080p]

This animation depicts the effect of the new Voyager scenario of the heliosphere on galactic cosmic rays. The heliospheric boundaries are very important in shielding the inner solar system from the galactic cosmic ray flux. The heliopause, the last region that separates us from the rest of the galaxy, acts more like a membrane that is permeable to galactic cosmic rays than a shield that deflects those energetic particles. The galactic cosmic rays slowly wander into the heliosphere and can get trapped in the sea of magnetic bubbles. Eventually they access the solar magnetic field lines that connect back to the sun, and can move quickly towards the sun and Earth.
