Short Definition:
The chemistry of cosmic objects or the chemistry of objects in space, such as the chemistry of the Moon, Mars, the Sun, asteroids, quasars, etc. and their effects on each other.
Detailed Definition:
Cosmochemistry is the study of the chemical compositions of matter in the universe and the processes that led to those compositions. Cosmochemistry is primarily done by studying the chemical compositions of cosmic objects or the chemistry of objects in space.
For example, carbonaceous meteorites were among the earliest formed bodies in the solar system. Their organic carbon is an indicator of chemical processes that occurred before the dawn of life on Earth. By studying carbonaceous meteorites and the origin and fate of their organic compounds, we begin to understand the general process of chemical evolution of organic molecules from interstellar space. Cosmochemistry also advances our knowledge of the physical and chemical processes in the distant past that might have had a significant role in the development of life in the universe.
“The spectral research on sulphur-containing radicals is of great significance in many fields such as atmospheric chemistry, combustion chemistry, cosmochemistry and so on.”
