Pulsar
PSR B1949+14 (J1952+1410)
Radio pulsar
A neutron star spinning once every 0.275 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 5,173 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 92 million years.
