In the sky
A telescope is needed to see it: its apparent magnitude is 10.95. Visible from the whole Southern Hemisphere and north to latitude 49° N. South of latitude 49° S it never sets. It stands highest at midnight in October, the best time to observe it.

Light's journey
The light you see tonight set out 13 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 225.1 billion years.
