Astronomy and astronomy-related topics have sufficient appeal and depth that they can be used to motivate students, illustrate important chemical concepts, and demonstrate that chemistry and chemists are concerned with all parts of nature. In this article some recent developments in astrochemistry are suggested as examples for the teaching of acid–base chemistry, molecular structure, and chemical reactivity. In a final section, work by astrochemists on the elusive carbonic acid molecule is described. Suggestions for additional reading are provided, with an emphasis on readily-accessible materials.
