> What amazes me the most is that we built something 35 years ago, shot it into space and it’s still going strong, sending radio signals from a place so far away that it takes 16 hours to get here.
I completely agree. I remember reading about Voyager 1 and 2 back in 1989, when I was a just a child, and thinking how cool it was that humans could build something to send into space and it could last so long. 23 years later, it is even more impressive that it is still out there and kicking... and may last another 10 years :) It is very impressive, to say the least.
One thing that really stuck in my mind when I heard the story was that, even 35 years later, "we're now a substantial fraction of a 'light-day' from the Earth..."
With the term "light-years" most commonly mentioned (eg, from a few days ago: http://www.geek.com/articles/geek-cetera/astronomers-find-su... ) I think hearing about light-hours and light-days helps to put things a little more into perspective (though it's all still mind-boggling).
