Light's journey
The light you see tonight set out 309 million years ago. At that time complex animals were spreading through the seas and over the land; there were no dinosaurs yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 5,472.8 billion years.
