What single entity forms the shared birthplace of stars in an open cluster?
Answer
Giant molecular cloud
The genesis of an open cluster is traced back to a single, massive parent structure known as a giant molecular cloud. Every star comprising the cluster originated from the gravitational collapse occurring within this immense cloud of gas and dust. Because they share this origin point and were formed at almost the exact same time, the stars within the cluster possess similar chemical compositions, functioning essentially as stellar siblings, despite variations in their individual masses depending on their position within the initial collapse.
