Its story

In Serpens, the only constellation split in two by the figure of the serpent bearer, glows a white A-type star, hotter and more luminous than the Sun, with that cold mineral purity of young stars. Its light takes around 241 years to arrive: what we see today departed about 1785, when William Herschel was proposing in London the first serious model of the Milky Way's shape by counting stars across the sky.
