Topic:101 Fuzzy Observations: Charles Messier and His Catalogue of Extra-Solar Objects
Introduction: Charles Messier (1730-1817) was a French astronomer who, throughout his lifetime, discovered a total of 13 comets; however, these were not his greatest contribution to astronomy. When searching for these comets, he would often come across fuzzy non-comet objects. As he was primarily interested in comets, these fuzzy objects were nothing but an annoyance to him. In order to aid him and other comet hunters like him, Messier kept a record of the location of these objects; the entire list he published in 1771. Nowadays, this list of 101 objects is known as the Messier catalogue and includes a wide variety of extra-solar objects, such as star clusters, supernova remnants, and nearby galaxies. Even today, his catalogue is still significant for both professional and amateur astronomers. Join us as we explore many of these same objects Messier discovered, including your favourite Messier object!
