Pulsar
PSR J0528+3529_P
Radio pulsar · binary system
A neutron star spinning once every 0.078 seconds; the beams from its magnetic poles sweep across Earth on every turn. It shares a 11.726 days orbit with a neutron star. Period, spin-down, distance and orbit come from the ATNF Pulsar Catalogue; the beam geometry is illustrative.

In the sky
Visible from the whole Northern Hemisphere and south to latitude 55° S. North of latitude 55° N 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 6,305 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 112 million years.
