During the Geologic Map Day on the October, 19th, the USGS presented a geological map of the moon. Created by the USGS Astrogeology Science Center, in collaboration with NASA – National Aeronautics and Space Administration and the Lunar and Planetary Institute, this first-ever comprehensive map reveals the moon’s entire surface geology, combining Apollo-era data with recent satellite missions.

Selenology is the scientific study of the Moon, encompassing its physical features, geology, and movements within the context of astronomy. The term derives from the Greek word “selene,” meaning Moon, combined with “logy,” which denotes a field of study.
Selenology focuses on various aspects of the Moon, including its surface characteristics, geological composition, and the effects of gravitational interactions with other celestial bodies.
The study of the Moon has evolved significantly since ancient times. Initial observations and mappings began in earnest during the 17th century with advancements in telescopic technology. The first detailed lunar maps were produced in the 18th and 19th centuries, marking significant milestones in selenographic research.
With the advent of space exploration, particularly during the 20th century, selenology has benefited from high-resolution imaging and data collected by lunar missions. These advancements have provided insights into previously unexplored regions of the Moon, enhancing our understanding of its topography and geological history.
Selenology can be considered a subdiscipline within planetary science and is closely related to selenography, which specifically deals with mapping and describing lunar features.
To sum up, selenology plays a crucial role in expanding our knowledge of the Moon’s characteristics and its significance within our solar system.
