An astronomical term that refers to a roughly spherical
cluster of gravitationally bound stars. A globular cluster
has anything from tens of thousands to a million individual stars
and can be ten to hundreds of light years across.
The Milky Way has around 200 globular clusters which
orbit the Galactic Core with a highly elliptical path that is
not confined to the Galactic Disk. Stars
in globular clusters tend to have low concentrations
of heavy elements, implying that the
stars in globular clusters are older than the stars
in the Galactic Disk.
It was from the observation of globular clusters that
Harlow Shapely was able to determine the Sun's position
in the Milky Way.

within our galaxy :) is at:
