Voyager spacecraft at edge of solar system

NASA's two Voyager spacecraft are will soon be passing in to the cold dark of interstellar space.
They have been traveling away from us for over three decades but despite their age the Voyagers are still returning data to Earth. Now as they approach the very edge of the solar system and prepare to pass outside of the heliosphere, a stream of charged particles given off by the sun, the two spacecraft will be the first man-made objects to leave the solar system completely and head off in to interstellar space.

Both Voyager probes were launched in the 1970s to take advantage of a rare planetary alignment facilitating an ambitious trip to all four gas giants, one of the most significant and groundbreaking space missions ever undertaken.
The Voyagers were built by NASA's Jet Propulsion Laboratory in Pasadena, Calif. , which continues to operate both spacecraft. JPL is a division of the California Institute of Technology in Pasadena.

Seriously. The Voyager probes make me proud to be a member of the human race. I first heard of them as a small child. Back then I thought the, astronauts in them must have been very lonely :-)

That's is so cool that the voyager probes are still going. I love hearing about where they are every few years.

How many more years until it reaches the end of our galaxy, on estimate?

"How many more years until it reaches the end of our galaxy, on estimate?" Probably outside the life time of this planet.

How many more years until it reaches the end of our galaxy, on estimate? It is currently travelling at a speed of 17.26 km/s (10.72 mi/s) and is travelling along the galactic plane (the "equator")... The first star it is scheduled to come near (it will miss it by about 1.6 light years) is AC+79 3888 (which is 17.6ly away)... It will take Voyager 1 roughly 40,000 years to pass AC+79 3888... Here is an excerpt from "Yahoo Answers" about the question how long until Voyager 1 leaves the Milky Way... "The diameter of the milky way is about 100,000 light years, whereby our sun is about 26,000 light ... [More]

I can't wait... I am so glad I was born in this age to see the first glimpse of inter-stellar space! I have a feeling it is going to be truly remarkable and game changer.
