Next Public Show — Wednesday, July 27, 2016
Topic:The Great Debate: Galaxies and their place in the Universe
Introduction: Less than a hundred years ago, many astronomers thought that the Universe consisted of just our home galaxy, the Milky Way. Others believed that the Milky Way was just one of many 'island universes'. Our journey through the night sky begins with these interesting patches of light, including the most famous Messier objects. Explore the Great Debate between astronomers Harlow Shapley and Heber Curtis, the arguments presented by each side, and how we know today that many of these spiral 'nebulae' are in fact spiral 'galaxies'. Finally, discover the importance of galaxies to our current understanding of cosmology and the Universe as a whole.
