Hot blue starIts story
In the kneeling silhouette of Hercules burns a blue B-class star, whose light set out some 1,226 years ago, when Charlemagne was being crowned Emperor of the West in St Peter's Basilica. B stars are massive, swift furnaces; they burn their fuel in a hurry and, in less time than the laws of the cosmos seem to allow, collapse as supernovae.
