Hot blue starIts story
In the starry shoulder of Perseus burns a blue-white beacon 748 light-years away, sister to the young clusters of the region. Its light departed around 1278, when Alfonso X the Wise was compiling in Toledo the Alfonsine Tables that would guide centuries of astronomy. A hot B-type vibrates at twenty thousand degrees, so many that its light tears electrons from the gases around it.
