The Department of Astronomy and Space, in collaboration with the Continuing Education Unit at the College of Science, University of Baghdad, organized a panel discussion titled “Globular Clusters.” The panel discussion aimed to introduce stellar clusters, spherical agglomerations of thousands of stars revolving around galaxies in huge orbits. Typically, stars within globular clusters are metal-poor, such as carbon, oxygen, and iron – elements that constitute the majority of rocky planets and living organisms. The panel discussion, presented by Assistant Professor Dr. Ahmed Hassan Abdullah, highlighted Globular Clusters (GCs) which are one of the spherical concentrations of 10^4 to 10^7 stars. These clusters are among the first stellar systems formed in the early universe. It was emphasized that most globular galaxies formed within a few Gyr after the Big Bang, and the universal characteristics of GC systems can be considered important traces of galaxy formation and evolution. The conclusion underscored the significant role of globular clusters in our understanding of differences among stellar groups and their implications for galaxy structure and evolution.
