In the sky
Too faint for the naked eye (magnitude 7.88); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 87° S. It stands highest at midnight in March, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1318. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
