Its story

In the silhouette of the Charioteer burns a blue type-O star, a rare beast among stars: blazingly hot, dozens of times more massive than the Sun, and with a brightness that wavers slightly. Its light has been travelling for 1,875 years: it set out when the Roman emperors of the second century reigned over an empire at its zenith, even before the founding of Constantinople. It is a blue lighthouse of classical Antiquity.
