Pulsar
PSR B0853-33 (J0855-3331)
Radio pulsar
A neutron star spinning once every 1.27 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.

Light's journey
The light you see tonight set out around the year 389. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 29 million years.
