Its story

In the sinuous coils of Hydra shines a blue B-type star, far hotter and more massive than the Sun, a bonfire destined to burn fast and die young. Its light needs about 506 years to cross the void: what we receive today departed around 1520, as Magellan was crossing the strait that would bear his name. Hydra, the largest of all constellations, unfolds its body like a dark river across the southern sky.
