In the sky
A telescope is needed to see it: its apparent magnitude is 12.42. Visible from the whole Southern Hemisphere and north to latitude 58° N. South of latitude 58° S it never sets. It stands highest at midnight in December, the best time to observe it.

Light's journey
The light you see tonight set out 26 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 462.9 billion years.
