Messier Monday: The Methuselah of Messier Objects, M56

Well, here on Messier Monday, we take a journey through the first catalogue to effectively do just that! Charles Messier catalogued, over many years in the late 18th Century, 110 deep-sky objects, each unique, and each telling its own tale. He was the original discoverer of a great many of these objects, including today's find, Messier 56. This is a globular cluster, which, to Messier in his modest (by today's standards) telescope, appeared as aNebula without stars, having little light. Some of the globular clusters have very dense central nuclei, others are more diffuse.
