Its story

A distant yellow star in Octans, the small southern constellation that wraps around the south celestial pole, almost two thousand light-years away. Its light set out around the dawn of our common era — before the Gospels were written — and has crossed a remarkable fraction of the galactic disc in silence to reach our instruments. Octans is one of the darkest constellations in the sky, yet it holds Sigma Octantis, the southern pole star toward which every Earthly axis in the south faintly points.
