Its story

In the small constellation of Lacerta, the celestial lizard, a bluish B-type star quivers 822 light-years away. Its variable light set out in the heart of the Middle Ages, when Gothic cathedrals were raising their spires toward the same sky that holds it. Far hotter than the Sun, its glow shifts with a subtle rhythm, as though it were breathing slowly. We gather it now, centuries later, a reminder that every glance at the sky is also a journey through time.
