Sky mapping is the process of systematically observing and documenting the celestial objects and features in the night sky. This can include mapping out the locations of stars, planets, galaxies, and other astronomical phenomena, as well as studying the spatial distribution and properties of these objects. Sky mapping is essential for astronomers to better understand the structure and composition of the universe, and is often done using telescopes, satellites, and other advanced imaging technologies. By creating detailed maps of the sky, scientists can track changes over time, identify new objects, and uncover important clues about the origins and evolution of the cosmos.
