Milky Way Globular Clusters
The positions of the 146 known Galactic globular clusters (from Bill Harris's compilation ) are plotted as black circles on top of the COBE FIRAS 2.2 micron map of the Galaxy using a Mollweide projection.

Here is a map where globular clusters with age determinations (49) are plotted as black circles, while the blue triangles are those globular clusters without age determinations. Note that very few clusters near the galacic center have age determinations.
