Pulsar
PSR B1046-58 (J1048-5832)
Young pulsar
A neutron star spinning once every 0.124 seconds; the beams from its magnetic poles sweep across Earth on every turn. Period, spin-down, distance and orbit come from the ATNF Pulsar Catalogue; the beam geometry is illustrative.

In the sky
Visible from the whole Southern Hemisphere and north to latitude 31° N. South of latitude 31° S it never sets. It stands highest at midnight in March, the best time to observe it.

Light's journey
The light you see tonight set out 9,459 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 168 million years.
