In the sky
A telescope is needed to see it: its apparent magnitude is 26.49. Visible from the whole Southern Hemisphere and north to latitude 60° N. South of latitude 60° 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 around 780 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 50 million years.
