The Halo has the oldest stars known witch includes 146 Globular clusters. Believed to have been formed in the early formation of the Galaxy with ages of 10 to 15 billion years from their H-R Diagrams. The Halo is also filled with a very diffuse, hot, highly-ionized gas. The very hot gas in the halo produces a gamma-ray halo.
