Serpens is a constellation located in the northern sky. It is unique because it is divided into two parts: Serpens Caput (the head) and Serpens Cauda (the tail). This constellation is home to several notable stars and deep-sky objects, including the Messier 5 globular cluster. The constellation is often associated with the myth of Asclepius, the Greek god of medicine, who was depicted holding a serpent. Serpens is best visible during the summer months in the northern hemisphere and is bordered by other constellations such as Ophiuchus and Hercules.
