In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.86). Visible from the whole Southern Hemisphere and north to latitude 66° N. South of latitude 66° S it never sets. It stands highest at midnight in May, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1550. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 8.4 million years.
