In the sky
Too faint for the naked eye (magnitude 8.96); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 39° S. North of latitude 39° N it never sets. It stands highest at midnight in February, the best time to observe it.

Light's journey
The light you see tonight set out 30 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 527.1 billion years.
