Which astronomer is credited with systematically documenting a significant collection of these objects with numerical designations that persist today?
Answer
Charles Messier
While others saw nebulae earlier, Messier was the first to systematically record a large group of them, assigning the numerical designations (like M42 and M27) that formed the basis for future study.
