Planetary Science explores the formation, evolution, and composition of planets and other celestial bodies in our solar system and beyond. It encompasses studies on planetary atmospheres, surfaces, interiors, magnetospheres, as well as their interactions with the sun and other cosmic phenomena. This field often employs theories and methods from chemistry to understand the geological and chemical processes that shape these celestial bodies. In the context of Astrobiology, Planetary Science contributes significantly by investigating the potential habitability of various planetary environments, as well as the search for extraterrestrial biosignatures. By integrating knowledge from fields like physics, geology, and mathematics, Planetary Science helps us unravel the mysteries of our cosmic neighborhood and deepen our understanding of the universe's intricate mechanisms.
