Which historical figure first cataloged planetary nebulae in the late 18th century?
Answer
William Herschel.
The initial cataloging and observation of these objects were performed by William Herschel during the late 18th century. When Herschel observed them through his telescopes, their small, round, greenish appearance led him to mistakenly associate them visually with the appearance of newly discovered planets like Uranus and Neptune, thus cementing the confusing term 'planetary nebula.' Herschel was instrumental in beginning the systematic classification of many deep-sky objects.
