Its story

In the belt of the hunter Orion shines a white type-A star, hotter and more luminous than the Sun, with a glow as clean as freshly broken ice. Its light has been travelling for 392 years: it set out when Galileo was writing his «Dialogue Concerning the Two Chief World Systems» and preparing to confront the Inquisition. It has travelled while modern science was being born painfully in southern Europe.
