Its story

Toward the Sails of the ancient Ship Argo burns a blue variable at 442 light-years, whose light set out when Tycho Brahe was observing the Cassiopeia nova and shaking the dogma of immutable heavens. It pulses like a slow lighthouse, altering its brightness in faint rhythms that betray atmospheric instability. It is one of the many blue jewels scattered across the southern sky, anonymous and fierce.
