Cometary chemistry

Cometary chemistry studies the composition of comets, which are icy bodies from the outer solar system. When comets approach the Sun, they heat up, causing their icy materials to vaporize and release gases and dust. This process creates a glowing coma and sometimes a tail. The chemistry of these materials often includes water, carbon dioxide, ammonia, and organic compounds, offering insights into the early solar system and the building blocks of life. Understanding cometary chemistry helps astronomers learn about the history of our solar system and the potential for life's ingredients beyond Earth.
