Some globular clusters are Messier objects, named after Charles Messier, who compiled a table of such objects to avoid mistaking them for comets. Today, the fuzzy objects in Messier's catalog (designated by number M1 - M113, but those after M103 were not in Messier's original list) are of more interest than the comets he sought. The following image displays the Messier objects found near the Milky Way in the region of Serpens Cauda, Scutum, Sagittarius, and Scorpius ( (img src)

The following figure is a schematic picture of our galaxy showing the halo with globular clusters.

Center of dense globular cluster M30. "This figure shows a schematic representation of the stars in the center of the dense globular cluster M30. The stellar density is approximately one million solar masses per cubic parsec in the central regions. Colors indicate stellar type: a red dot indicates a red giant branch or a subgiant star, green dots are horizontal branch stars, blue represents blue straggler stars and, white dots represent main sequence stars. The size of each dot is proportional to the stars brightness, with the biggest dots corresponding to V magnitude 14 stars and the faintest dots corresponding to V magnitude 21.5 stars. The cluster M30 contains a higher proportion of blue straggler stars in it's center than any other known globular cluster. The green cross marks the dynamical center of the cluster. This image was may by processing a set of multi-color exposures from the WFPC-2 camera of the HST. " (Source)
