Its story

It burns with a bluish flash at the heart of Scorpius, a B-type giant whose light began its voyage when Galileo was still defending his telescopes before the Roman Inquisition. Hotter and more massive than the Sun, its glow crossed 555 years of vacuum before reaching our eyes. To see it is to glimpse a century of scientific revolutions, when astronomy ceased to be dogma and became a patient gaze upon the sky.
