In the sky
A telescope is needed to see it: its apparent magnitude is 10.74. Visible from the whole Northern Hemisphere and south to latitude 41° S. North of latitude 41° N it never sets. It stands highest at midnight in May, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1497. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 9.4 million years.
