Is Scorpio nebula a galaxy?

Scorpio is a constellation, not a nebula, not a galaxy. Constellation refers to the pattern composed of stars in the sky. Since ancient times, human beings have associated three or five stars with their mythical figures or artifacts, which are called "constellations". In ancient times, the rise and fall of stars or constellations were often used to navigate and determine time. Constellations and the literary images they represent often appear in the works of literati.
