What is Messier 71?
Messier 71 is a rather unremarkable looking little cluster in the constellation Sagitta, but astronomers have puzzled over exactly what it is for many years. It has characteristics of both an open cluster and a globular cluster. The general consensus is, I believe, that it is a relatively young globular cluster (9 to 10 billion years old) with a loose grouping of stars.
