Classification of 1855

The Classification of 1855 was a major effort by British astronomers to organize and categorize nebulae and star clusters. They divided these celestial objects into different groups based on their appearance and characteristics, such as brightness and structure. This system helped astronomers better understand and study the universe by creating a standardized way to identify and compare these objects. It was an important step in the development of modern astronomy, providing a foundational framework for future classifications and discoveries.
