Hunting for astronomical fossils with Keck

Ancient star clusters are the fossils of the astronomical world. They formed at early times in the Universe and many have survived to the present day. New discoveries made with the Keck Observatory have uncovered a host of previously unknown star clusters - some more massive than small galaxies. Join us for an engaging presentation by Professor Duncan Forbes from Swinburne University, Australia, as he shares his current research and asks us all to consider, "What is a galaxy?"
