Its story

In Serpens, the snake held by Ophiuchus high in the summer sky, burns a blue B-type star, far hotter and more massive than the Sun. Its light took roughly 708 years to cross the void: it departed in the early 14th century, when Dante was completing the «Divine Comedy» and Europe was living under the chill of the late Middle Ages. A blue pulse, ancient and fierce, traces the serpent's scales.
