HIP 82110
Hot blue starWhat is HIP 82110
In ancient Ara, the votive altar of the southern sky, burns a blue B-type star at 985 light-years. Its light set out around the year 1040, at the height of the Caliphate of Córdoba and while Avicenna was writing his «Canon of Medicine» in Persia. It is a blue-white furnace, thousands of degrees hotter than the Sun, watched over by a constellation that evokes a sacrificial fire.
