Like the flocks of waterfowl during migration, there are many stars in V-shaped arrangement. If you've experienced the spectacular scenes of migratory bird migration, you won't be unfamiliar with the magnificent scenery of Messier 11.

It is reported that Messier 11, classified as an open cluster by astronomers, was formed about 220 million years ago.ESA explained that:

Open clusters tend to contain fewer young stars than globular clusters. This means that they can be separated very far, so we are not optimistic about the future of Wild Duck Cluster.

ESA said Messier 11 could collapse in millions of years. The members of the galaxy will be "persuaded to retreat one by one" and then be pulled away by other nearby celestial bodies, so let's "watch and cherish it".
