蛇夫座, or Ophiuchus, is a constellation located near the celestial equator. It is often depicted as a man holding a serpent, symbolizing the struggle between healing and conflict. This constellation is recognized as the 13th sign of the zodiac, although it is not commonly included in traditional astrological charts. Ophiuchus contains several notable stars and deep-sky objects, including the bright star Ras Alhague. The constellation is best visible in the northern hemisphere during the summer months and is associated with the myth of Asclepius, the Greek god of medicine, who is often linked to healing and the serpent.
