Co

Definition

'Co' is a chemical symbol for carbon monoxide, a colorless, odorless gas that is formed by the incomplete combustion of carbon-containing fuels. It plays a crucial role in the study of molecular clouds, where it serves as an important tracer for identifying regions of star formation and molecular activity within these dense, cold regions of space. The presence of 'co' in molecular clouds indicates the processes involved in the formation of stars and the molecular composition of interstellar material.
