Hot blue star

Its story

On the throne of Cassiopeia burns a blue B-type beacon, about 603 light-years away. Its light began traveling around 1423, in the early Renaissance, when Brunelleschi was designing the impossible dome of Santa Maria del Fiore in Florence. Its surface comfortably exceeds 10,000 degrees, a cold violent gleam stitched into the seams of the stellar W.
