In the sky
A telescope is needed to see it: its apparent magnitude is 14.00. Visible from the whole Southern Hemisphere and north to latitude 53° N. South of latitude 53° S it never sets. It stands highest at midnight in September, the best time to observe it.

Light's journey
The light you see tonight set out 25 million years ago. At that time the dinosaurs were gone and mammals were diversifying; there was no human lineage yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 439.7 billion years.
