The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
Clusters - either open or globular.
Harlow Shapley studied globular clusters and used the position of the clusters to locate the sun in the middle of our galaxy. He found out he was wrong but figured out that the sun was in one of the spiral arms in our galaxy
A globular cluster is a part of a galaxy, usually found in the halo surrounding the galactic center. Globular clusters are densely packed groups of thousands to millions of stars held together by gravity. They orbit the center of their host galaxy along with other components such as the spiral arms and bulge.

Planet earth is not in any of the approximately 150 globular clusters which are known to exist in our galaxy, the Milky Way. Our solar system is on one of the spiral arms of the Milky Way.
It is currently believed that all spiral galaxies have a supergiant black hole at their centers and all galaxiesand globular clusters have several ordinary black holes scattered throughout them.

The Milky Way galaxy is a spiral galaxy with a central bulge, a disk made up of arms of gas, dust, and stars, and a halo of globular clusters. The central bulge contains older stars, while the disk is where younger stars are formed. The galaxy is surrounded by a halo of dark matter that extends beyond the visible components.
Galaxies are primarily classified according to their shape. Such as spiral, elliptical, and globular.
The Milky Way Galaxy is a spiral galaxy and open clusters are only found in spiral or irregular galaxies.
