Its story

In the Stern of the ancient celestial ship glows a blue star of oscillating light whose signal set out nearly twelve hundred years ago, when Charlemagne was crowning a short-lived empire. It pulses with a slow rhythm, almost a cosmic breathing, which places it among the observable variables. It is a hot giant, far more luminous than the Sun, able to remain visible across such a distance under clean skies. Its shifting brightness reminds us that even stars have inner seasons.
