Globular clusters are a natural congregation of stars born together in primeval clouds of Hydrogen and Helium in the early periods of the Universe. Globular clusters from the time of discovery in 1665 through the analysis of extragalactic globular clusters with the latest space telescopes constantly provide new information about the earliest ages of the Cosmos and the evolution of stars. Despite the latest results of scientific data and spectral insights into these fascinating structures, there are many unknowns and mysteries about globular clusters. The continuous discovery of globular clusters in the Milky Way galaxy is a hot field of astronomy even in the early 21st century.

This presentation will discuss the history of astronomical analysis of globular clusters, from their discovery to the latest information and theories about the nature of globular clusters. Tips and methods for observing globular clusters are a part of this discussion, combining photographic and spectrographic analysis to reveal the mysteries of globular clusters.
