In the sky
A telescope is needed to see it: its apparent magnitude is 11.52. Visible from the whole Southern Hemisphere and north to latitude 69° N. South of latitude 69° 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 1415. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
