Hot blue starIts story
In the bearer of the serpent, Ophiuchus, burns a blue B-class star whose light set out some 738 years ago, when Marco Polo was dictating in a Genoese prison the account of his travels to Cathay. B stars are hot, massive bodies, rich in hydrogen and helium, with surfaces several times the Sun's temperature and lives much shorter than that of the Sun.
