Voyager 1 at the Final Frontier
In short: V’Ger 1 is detecting a sudden increase in cosmic rays… indicating that it is at the edge of the heliosphere. This is the “bubble” around the solar system formed by the suns magnetic field. Within this bubble, the suns forces dominate… outside the bubble, the sun is insufficiently powerful to counter the rest of the universe. So, cosmis rays, which are partially mitigated by the heliosphere, are allowed to run riot in interstellar space… and it seems that V’Ger 1 is about there.
