In the sky
A telescope is needed to see it: its apparent magnitude is 10.50. Visible from the whole Southern Hemisphere and north to latitude 72° N. South of latitude 72° 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 33 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 578.6 billion years.
