Planetary scientists study planets, moons, and other celestial bodies in our solar system and beyond. They analyze the composition, structure, and processes of these objects to understand their formation and evolution. This field combines aspects of geology, astronomy, and physics to explore phenomena such as volcanoes, atmospheres, and surface features. These scientists often use data collected from space missions, telescopes, and laboratory experiments. They may work on projects related to Mars, Jupiter's moons, or even exoplanets outside our solar system. Their research helps us learn more about the universe and our place within it.
