Hot blue star

Its story

At 1,080 light-years on the wing of Cygnus, this hot B-type blue burns with the raw energy of stellar youth. Its light set off around the year 940, when Caliphal Córdoba was the largest and most learned city in Europe and al-Andalus calculated longitudes with instruments inherited from the Greeks. It arrives tonight without delay or hurry.
