Biography
Charles Messier was a dedicated French comet-hunter who grew tired of mistaking fuzzy, unmoving objects for comets. To avoid the confusion he listed them — galaxies, nebulae, and star clusters — in a catalogue of about 110 entries. That list of 'nuisances' became one of the most beloved observing guides in all of astronomy.
