NASA's Voyager 1 began it's journey in 1977 leaving Earth for the unknown. It has been surfing the solar winds for this entire time taking pictures along it's journey and slowly updating it's Facebook status update.
It's now on it's way out of our solar system and nearing the edge of the Heliopause (the official edge of our solar system). Voyager 1 is currently a staggering 10-billion miles away and it issuing out "solid zeroes" which means it's not detecting any more outward movement from solar winds.
This is a very large achievement for the human race, sending something out this far and it not breaking down or faulting at all is a massive achievement in itself.
