Voyager I is now 11 billion miles from the sun and at the end of our solar system.  NASA calls the area cosmic purgatory.

For the past year using the several instruments at its disposal Voyager I shows no solar wind is going either way.  The stagnation area is where our solar system's magnetic field has piled up and is slowly leaking into interstellar space.

Voyager I was launched in 1977 and slowly reaching her destination.
