Globular Cluster Messier 71 (M71) in Sagitta

Sagitta is a small constellation found between the bright stars Vega and Altair. The name is Latin for arrow and represents the weapon that Hercules used to kill the eagle (Aquila). There is one nice Messier object contained in this constellation, the globular cluster designated as M71. The famous Dumbbell Nebula lies nearby, but it lies just over the border in the constellation Vulpecula.

M71 is about 12,000 light years away from Earth and is about 27 light years across. Up until the 1970’s this cluster was designated as a densely packed open cluster because of the loose central region, today it is designated as a loosely concentrated globular cluster with a young age of 9-10 billion years.
