Arches Cluster
The Arches Cluster is an open cluster in Sagittarius constellation that was discovered in 1995. It is the densest star cluster of its kind known in the Milky Way.
The Arches Cluster was named for the arch-shaped filaments detected in its vicinity at radio wavelengths. These filaments are produced as a result of the cluster approaching and ionizing the surface of a molecular cloud that lies in the background.
