Globular clusters are spherical concentrations of stars typically 100 light years across and containing thousands of stars. Globular clusters are very old, at least 10 billion years old and were presumably formed when the galaxy was still forming. They are scattered in a spherical halo surrounding our galaxy and they require hundreds of millions of years to orbit it.
Below is a list of most of the globular clusters that surround our galaxy.

Column 1: Usual catalog number of the globular cluster.
Column 2: Other name (usually a Messier number).
Column 3: Right Ascension in hours and minutes for epoch 2000.
Column 4: Declination in degrees and minutes for epoch 2000.
Column 5: Galactic longitude of the globular cluster.
Column 6: Galactic latitude of the globular cluster.
Column 7: The visual magnitude.
Column 8: Approximate angular diameter of the globular cluster in arcminutes.
(This is a rough estimate of the cluster's visual isophotal diameter.)
Column 9: Distance to the globular cluster in thousands of light years.
The error on these distances is typically about ±10%.
Column 10: Constellation the globular cluster is in.
