Astronomical catalogues
Astronomical catalogues are comprehensive lists that organize and describe celestial objects, such as stars, galaxies, and nebulae. These catalogues provide important information, including positions, distances, brightness, and other characteristics, which helps astronomers study the universe. Popular catalogues include the Messier Catalogue, which lists visible deep-sky objects, and the Hubble Space Telescope's catalogues, which document findings from space observations. By systematically categorizing these objects, astronomers can better understand their properties, relationships, and the overall structure of the universe.
