Thirty-three years ago NASA launched the Voyager space probes. After all these years they have arrived at the very edge of our solar system. Watch what they have found, it is truly astonishing:
The signals Voyager sends back to earth now take over 16 hours to reach us and I find it miraculous that the probes still survive in the very hostile environment of space. May Voyager I and II continue on their way for a long time and reveal to us more secrets of our incredible universe.
