Light's journey
The light you see tonight set out 694 million years ago. At that time the Earth held only single-celled organisms and the first multicellular life. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12,302.3 billion years.
