Astrochemistry
study of the abundance and reactions of chemical elements and molecules in the universe / From Wikipedia, the free encyclopedia
Astrochemistry is the study of how atoms react with each other outside our planet. They make the molecules in planets, stars, and other stellar things.[1]
It is a combination of astronomy, astrophysics, and chemistry. Astrochemistry is sometimes combined with nuclear physics when dealing with the nuclear reactions that happen within stars. Astrochemistry is different from cosmochemistry as astrochemistry talks about things outside our Solar System, while cosmochemistry talks about things within the Solar system.[2]
