Its story

Draco coils around the celestial north pole, one of the most extensive and ancient figures of the firmament. Among its scales glows this white A-type star — young and hot — whose light took about 345 years to arrive. It set out when Galileo was finishing his last years under house arrest for defending the heliocentric model, and the sky was slowly ceasing to be a dogma to become a map instead. That white light, still loaded with nuclear youth, is a silent witness to that change of paradigm.
