Its story

Beneath the Keel of the Argo burns a blue giant whose light took 1,437 years to reach us. When it left, the Western Roman Empire had just collapsed and barbarian kingdoms were redrawing the map of Europe. A class-B sun —blue-white, several times hotter and thousands of times more luminous than ours—, it embodies that furious stellar youth that scarcely lasts a few tens of millions of years.
