Which constellation contains the deep sky object known as the M13 globular cluster?

The M13 globular cluster, also referred to as the Great Hercules Cluster, is located within the constellation Hercules. This cluster is one of the brightest and most easily observable globular clusters in the northern hemisphere, making it a popular target for amateur astronomers and telescope users. M13 contains hundreds of thousands of stars densely packed together, and its location in Hercules makes it particularly noteworthy for those studying the structure and formation of star clusters.

The choice of Hercules as the correct answer is significant because the constellation is prominently positioned in the sky and provides a clear view of M13. It is well known in astronomical literature for this particular deep-sky object.

In contrast, the other constellations listed do not contain M13. Orion, characterized by its distinct belt of three stars, and Perseus, known for its variable star Algol and connection to mythology, do not host this specific globular cluster. Taurus, recognized for its bright stars and the Pleiades open cluster, is also unrelated to M13. Thus, the specific association of M13 with the constellation Hercules makes it the correct answer.
