In the sky
A telescope is needed to see it: its apparent magnitude is 11.46. Visible from the whole Northern Hemisphere and south to latitude 72° S. North of latitude 72° 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 43 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 754.5 billion years.
