Of Comets, Ferrets, and Nebulae: Charles Messier, his Discoveries and his World
In the 18th century the nature of comets and their orbits fascinated astronomers, and no one more than Charles Messier, who discovered 13 of them. So famous was his comet-hunting that his King, Louis XV, nicknamed Messier the ‘Ferret’ of comets. Yet he was so frustrated by the nebulous blobs which he sometimes mistook for comets that he compiled a list of these ‘nuisances’. This ‘Messier Catalogue’ would immortalise him, and would go on to become the bedrock of deep-space astronomy. France had a very dynamic scientific community in Messier’s time, and we will see him in the context of the great French astronomical achievements of the age. Surviving the French Revolution, Messier died in 1817, aged 87.
