Astrogeology is the study of geological features and processes on celestial bodies such as planets, moons, asteroids, and comets. This field combines principles of geology and planetary science to investigate the formation, composition, and evolution of planetary surfaces. Astrogeologists use remote sensing data, such as images and spectra, to study the geology of these bodies and understand the geological processes that have shaped them. By studying astrogeology, scientists can gain insights into the history and potential habitability of other worlds in our solar system and beyond.
