Overview – Globular Clusters: How to see them in a different light

To the casual observer, Globular Clusters are the ‘pretty faces’ of the night sky. Apart from a few bright standouts, little seems to distinguish one from another. To the scientist, they are ancient remnants of the ‘big bang’, with an accepted morphology and a settled science. These traditional assumptions are now being seriously challenged. This talk places Globular Clusters in their context, as singular members of our galaxy and reveals them to be highly individualistic and dynamic rather than static objects. These mysterious objects, hitherto somewhat neglected by mainstream astrophysics, are now receiving more attention and their story is being rewritten.
David Allan has been a member of the Astronomical Association of Queensland (AAQ) and the Brisbane Astronomical Society (BAS) for almost two decades. He was recently Visual Observing Reporter for AAQ for a period of 5 years and developed a particular interest in galactic and globular clusters.
