Its story

45 Andromedae is a blue-white B-type star 790 light-years away, in the constellation of the chained princess. Its light set out around the thirteenth century, when the kingdoms of Castile and Aragon had yet to unite and illuminated manuscripts were the chief vehicle of knowledge. B stars like this burn at tens of thousands of degrees, pouring out a bluish light that evokes the hottest fire in the sky.
