Pulsar
PSR J1326-4728H_P
Millisecond pulsar · in the globular cluster OmegaCen(NGC5139)
A millisecond pulsar spinning 397 times per second: an old neutron star spun up again (“recycled”) by matter transferred from a companion. It shares a 3.26 h orbit with a very-low-mass companion. 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 21 thousand years ago. At that time Homo sapiens was spreading out of Africa; there was no farming yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 371 million years.
