In the sky
A telescope is needed to see it: its apparent magnitude is 16.44. Visible from the whole Northern Hemisphere and south to latitude 20° S. North of latitude 20° N it never sets. It stands highest at midnight in March, the best time to observe it.

Light's journey
The light you see tonight set out 12 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 214.1 billion years.
