Voyage of a Lifetime

On September 12 this year NASA announced that Voyager 1 had left our solar system and entered inter-stellar space.  In doing so, it became the first man-made object to leave our solar system.

This is very impressive stuff but when you also hear that it was launched in 1977, it makes you realise that a return trip would take 72 years: literally, a lifetime.

So I guess, we're not going anywhere far, far away, anytime soon!
