Hot blue starIts story
In the southern Compass —a constellation traced by Lacaille in the 18th century— burns a very distant blue star, 1,681 light-years away. Its light set out around the year 345, when Constantine the Great was consolidating his new capital on the Bosphorus. Very hot B-type stars are brief sparks: they live for millions of years, not billions, and often die as supernovae.
