Its story

μ Ophiuchi burns at 755 light-years, a blue-white B-class sun within the body of the Serpent Bearer — that vast figure holding the Serpent in both hands. A young, hot star, it belongs to the kind that lights the spiral arms and burns through life in a cosmic blink. The light now crossing our sky left the Ophiuchus region when the first medieval universities were rising in Europe.
