PSR J1910+0423_P

Radio pulsar · binary system

A neutron star spinning once every 0.093 seconds; the beams from its magnetic poles sweep across Earth on every turn. It shares a 894 days orbit with a helium white dwarf. 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 43 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 757 million years.
