In the sky
Too faint for the naked eye (magnitude 8.65); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 42° N. South of latitude 42° S it never sets. It stands highest at midnight in December, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1906. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.1 million years.
