Variable star

Its story

Red, cool, vast and trembling: an M-class variable lost in the silhouette of Cepheus, 2,452 light years away. The light now grazing the atmosphere set out around the year 426, in the midst of the fall of the Western Roman Empire. Its M class and slow variability sketch an aged supergiant that pulses unhurriedly, swelling and shrinking like a cosmic lung.
