Does this shift the Zombie Apocalypse left or right, or has Voyager really not left the galaxy yet...?
or has Voyager really not left the galaxy yet...?
It clearly has not left the galaxy yet. Nor will it ever. ;)

PatThanks, I feel better now. (http://www.spacetoday.org/SolSys/Voyagers20years.html)
The heliopause is somewhere between 5 and 14 billion miles from the Sun. It never has been reached by any spacecraft from Earth, so the Voyager twins will be the first human-built spacecraft from Earth to pass through that region.
The Voyagers have enough electrical power and thruster fuel to operate at least until 2020. By that time, Voyager 1 will be 12.4 billion miles from the Sun and Voyager 2 will be 10.5 billion miles from the Sun.
Eventually, the Voyagers will pass other stars:
Voyager 1, in 40,000 years, will float by within 1.6 light years (9.3 trillion miles) of a star known as AC+79 3888 in the constellation Camelopardalis.
Voyager 2, in 296,000 years, will sail within 4.3 light years (25 trillion miles) of Sirius, which today is the brightest star in Earth's sky.
Voyager 1 and Voyager 2 are destined to wander through our Milky Way galaxy eternally — unless they crash into something we can't yet calculate. :eek: Pete says "never say never."
:D
