voyager 1 has buggered off and left us

So, NASA have agreed that Voyager 1 has now gone and entered interstellar space, which is an amazing accomplishment when you think that it was built using 1960's and 70's technology.
The above photograph was taken by Voyager in 1990, and it shows the Earth, a long way in the distance. Since then, we are a lot further away, and in another 40,000 years Voyager will be closer to star AC+79 3888 than our own sun (and the star is heading towards us faster than we are going towards it!). To state that space is vast is somewhat of an understatement.
