Its story

A white A-type star shines coolly within the constellation of Auriga, the ancient celestial charioteer. Hotter and more luminous than the Sun, its light began travelling some four and a half centuries ago, when Tycho Brahe was building Uraniborg and recording the heavens with unprecedented precision. After 453 light-years of silent journey, its bluish-white glow arrives tonight, faithful messenger of an age in which patience and instruments first joined to measure what lay above.
