Extraterrestrial geology is the study of the geology of other planets, moons, and celestial bodies in our solar system and beyond. This area of research focuses on understanding the physical and chemical processes that shape the surfaces of these bodies, including their compositions, structures, and histories. Scientists use data gathered from spacecraft missions, telescopic observations, and laboratory experiments to study extraterrestrial geology and gain insights into the geological processes that occur beyond Earth. This research provides crucial information about the evolution and environmental conditions of other planetary bodies, as well as their potential for supporting life.
