Explore the chemistry of stars, planets, comets, and the universe beyond.
Chemistry is not just confined to Earth. From the fiery cores of stars to icy comets and mysterious interstellar clouds, the universe is a laboratory of molecules and elements. Cosmic Chemistry (or astrochemistry) studies how atoms and molecules form, interact, and transform across space. This field bridges astronomy, physics, and chemistry, helping us understand the origin of elements, the formation of planets, and the building blocks of life beyond Earth.
On this page, you’ll find a comprehensive roadmap of topics in cosmic chemistry, along with links to detailed posts, research insights, and cutting-edge discoveries.
