In the sky
A telescope is needed to see it: its apparent magnitude is 25.10. 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 25 thousand years ago. At that time Homo sapiens was spreading out of Africa; there was no farming yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 437 million years.
