Hot blue star

Its story

In Cassiopeia, the queen enthroned in the northern sky, shines a blue-white B-type star, young and far hotter than the Sun. Its light left its surface around 405 years ago, when Kepler had just published the laws of planetary motion and blown-glass telescopes were beginning to multiply the visible sky. It arrives now on time, with the sharp edge that defines a bluish sun.
