Pulsar
PSR B1010-23 (J1012-2337)
Radio pulsar
A neutron star spinning once every 2.52 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 1181 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 57 million years.
