Pulsar
PSR J1810-0623
Millisecond pulsar · binary system
A millisecond pulsar spinning 220 times per second: an old neutron star spun up again (“recycled”) by matter transferred from a companion. It shares a 15.376 days orbit with a CO white dwarf. 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 84° N. It stands highest at midnight in June, the best time to observe it.

Light's journey
The light you see tonight set out around the year 1351. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12 million years.
