In the sky
A telescope is needed to see it: its apparent magnitude is 13.45. Visible from the whole Southern Hemisphere and north to latitude 76° N. South of latitude 76° S it never sets. It stands highest at midnight in April, the best time to observe it.
Light's journey
The light you see tonight set out around the year 430. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 28 million years.
