Its story

It shines in Hercules, the immortal hero of the twelve labours, one of the oldest constellations in the northern sky. A white A-type star, hotter and brighter than the Sun, its light took some 456 years to cross space: it set out around 1570, when Tycho Brahe was observing the famous supernova SN 1572 and proving that the heavens were not immutable. A white glimmer among the celestial muscles of the Greek hero.
