In the sky
A telescope is needed to see it: its apparent magnitude is 27.40. Visible from the whole Southern Hemisphere and north to latitude 63° N. South of latitude 63° S it never sets. It stands highest at midnight in June, the best time to observe it.
Light's journey
The light you see tonight set out 8,382 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 149 million years.
