Cometary science

Cometary science studies comets—icy, rocky bodies from the outer solar system that develop glowing comas and tails when they approach the Sun. Scientists investigate their composition, structure, and behavior to understand the early solar system's conditions. Comets carry primitive material from its formation 4.6 billion years ago, offering clues about planetary origins. They provide insights into volatile compounds and organic molecules, informing theories about the development of life. Missions like Rosetta and comet observations help us learn how these icy visitors evolve, interact with solar wind, and influence planetary environments. Overall, cometary science uncovers the history and fundamental processes shaping our cosmic neighborhood.
