In the sky
Too faint for the naked eye (magnitude 6.51); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 15° N. South of latitude 15° S it never sets.
Light's journey
The light you see tonight set out around the year 1896. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.3 million years.
