New General Catalogue (NGC)

The New General Catalogue (NGC) is a comprehensive collection of over 7,800 astronomical objects, mainly galaxies, star clusters, and nebulae, compiled in the late 19th century by John Louis Emil Dreyer. It serves as a key reference for astronomers, providing standardized identifiers for these deep-sky objects observed through telescopes. The NGC helps researchers and enthusiasts locate and study celestial objects, offering detailed descriptions and coordinates. Over time, the catalog has been expanded and refined, becoming an essential resource for understanding the structure and composition of the universe.
