This looks like more evidence that Globular Clusters might be formed inside of galaxies, rather than being the oldest building blocks. Very interesting!!!

Wondering if this is like the 2MASS group where they are all suns and black holes.

A quick check shows that the Arches Cluster isn't in the Galaxy Map.
Pity really.

The only cluster I've found in the galaxy map is the open cluster in Orion. But I've only seriously looked for globular clusters.
